Introduction

This chapter contains information to migrate data from ACS 4.x to ACS 5.2. Before you begin, you must follow the setup, backup, and installation instructions in Chapter 5 "Migration Utility Setup and Installation."


Note Before you begin migration, ensure that you have enabled the migration interface on the ACS 5.2 server.

From the command line interface, enter:

acs config-web-interface migration enable

To verify that the migration interface is enabled on the ACS 5.2 server, from the command line interface, enter:

show acs-config-web-interface

Refer to the Command Line Interface Reference Guide for the Cisco Secure Access Control System 5.2 for more information.


Running the Migration Utility

To run the Migration Utility:


Step 1 Open a command prompt and change directory to C:\Migration Utility\migration\bin

You can specify any directory in which to install the Migration Utility. This example uses the Migration Utility as the root directory.

Step 2 At the command prompt, type migration.bat.


Example 6-1 shows the prompts that appear when you run the Migration Utility.

---------------------------------------------------------------------------------------
This utility migrates data from ACS 4.x to ACS 5. You can migrate directly from the 
following ACS versions:
 
   
- ACS 4.1.1.24
- ACS 4.1.4
- ACS 4.2.0.124
- ACS 4.2.1
 
   
Data migration involves the following:
a. The migration utility analyzes the ACS 4.x data, exports any data from ACS 4.x that can 
be migrated automatically, and imports the data into ACS 5.
b. Before the import stage, you can manually consolidate and resolve data according to the 
analysis report, to maximize the amount of data that the utility can migrate.
c. After migration, use the imported data to recreate your policies in ACS 5.

Note The group's Single Connect flag overwrites the device's Single Connect flag.



Note TACACS+ Single Connect feature is present in ACS 5.2 by default. It is not migrated by the migration tool from ACS 4.x to 5.2.


Analysis and Export

There are three major differences between the AAA Client (ACS 4.x) and Network Device (ACS 5.2) definitions:

In ACS 5.2, it is possible to define one network device that handles both RADIUS and TACACS+, while in ACS 4.x, two different AAA clients are required.

In ACS 5.2, IP address is defined as a pair consisting of an IP address and a mask, while in ACS 4.1, IP address is defined using regular expressions.

In ACS 5.2, each network device definition is limited to storing 40 IP addresses. In ACS 4.x, it is possible to define more than 40 IP addresses.

This section contains:

Unsupported Characters in a Device Name

Overlapping IP Addresses

IP Address Translation

IP Subnets Limit

Unsupported Characters in a Device Name

Some special characters are not allowed in the device name during export. You will get an error message during the analysis and the export will not proceed if the following characters are used in the device name:

{} " '

Overlapping IP Addresses

In ACS 4.x, you can create definitions with overlapping IP addresses as part of a network device, where the first IP address utilizes TACACS+ and the second IP address utilizes RADIUS.

In ACS 5.2, TACACS+ and RADIUS are unified within a single network device definition. However, the unification is not possible if TACACS+ and RADIUS are part of different NDGs in ACS 4.x.

In the migration analysis phase, the network group and overlapping IP addresses are identified and reported to the administrator so that these definitions can be modified to conform to the ACS 5.2 requirements.

For example:

Network device AA: IP address = 23.8.23.*, 45.67.*.8, protocol = RADIUS, group = HR

Network device BB: IP address = 45.*.6.8, 1.2.3.4, protocol = TACACS, group = Admin

In this example, the second IP address in the AA network device list overlaps the first IP address in the BB network device list, and each of the network devices is part of a different NDG.

Consolidation between separate entries for RADIUS and TACACS+ network devices is possible only if the IP addresses are identical and both of the network devices are part of the same NDG. All consolidation is reported in the Analysis report.

IP Address Translation

In ACS 5.2, the IP address is in the form of a subnet mask, whereas in ACS 4.x, the IP address definition can include wildcards and ranges. Not all combinations of IP address ranges in ACS 4.x are translated into a subnet mask definition in ACS 5.2.

For example:

Network device AA: IP address = 23.8.23.12-221, protocol = RADIUS, group = HR

In this example, the IP address in the AA network device cannot be translated into the subnet mask format of ACS 5.2.

An IP address that contains ranges or a wildcard in the middle of the address cannot be exported. For example, the following IP address patterns cannot be translated:

1.*.2.*,

*.*.*.1,

*.*.*.*

1.2.3.13-17

The following IP address patterns can be translated:

1.*.*.*

1.2.*.*

1.2.3.*

In the migration analysis phase, network groups with untranslatable IP addresses are identified and reported to the administrator so that they can be modified to conform to ACS 5.2 requirements for subnet mask definitions.

IP Subnets Limit

The migration analysis process identifies the network devices with more than 40 IP subnets and reports that these devices cannot be migrated. To allow migration, you can change them to subnet masks or split them into multiple network device definitions to conform to the ACS 5.2 format. Table 6-6 describes the ACS 4.x attributes that can be modified to conform to ACS 5.2 limitations.

Key Wrap Attributes

The keys that contain the following characters are identified during the analysis phase:

27 HEX

22 HEX

An error message message appears during the analysis phase and the export will not proceed, if any of the following characters are found in the network device's Key Encryption Key or in the Message Authenticator Code Key:

' "

Table 6-6 describes the ACS 4.x attributes that can be modified to conform to ACS 5.2 limitations.

Table 6-6 Attribute Modification

Attribute Name in 4.x
Comment

Authentication using

Any selection for a specific RADIUS vendor is translated to Authenticate Using RADIUS. For example, RADIUS (Cisco Aironet) is translated to RADIUS.

AAA Client IP Address

The IP address in ACS 5.2 is in the form of a subnet mask, whereas in ACS 4.x, the IP address definition can include wildcards and ranges.

The export process translates the combination of IP address range that can be translated into a subnet mask definition.

Shared Secret

For devices that belong to an NDG where the NDG includes a shared secret.

The NDG's shared secret is extracted and included in the network device definition, instead of in the network device definition shared secret.

Key Encryption Key

For devices that belong to an NDG where the NDG includes a Key Encryption Key.

The NDG's Key Encryption Key is extracted and included in the network device definition, instead of being defined with the network device definition Key Encryption Key.

Message Authenticator Code Key

For devices that belong to an NDG where the NDG includes a Message Authenticator Code Key.

The NDG's Message Authenticator Code Key is extracted and included in the network device definition instead of being defined with the network device definition Message Authenticator Code Key.


Import

The Unified Device Name setting is used during import of network devices. In ACS 5.2, configuration options are available to determine the name of the new device in ACS 5.2, if there are separate RADIUS and TACACS+ devices in ACS 4.x that can be unified into a single network device definition. The following options are available in ACS 5.2:

Name of RADIUS Device

Name of TACACS+ Device

ACS 4.x contains a single-level hierarchy between a network device and an NDG. Each defined network device (AAA client) must be included in one of the NDGs. To keep this association between the network device and the NDG, ACS 5.2 first exports and imports the NDGs, and then the network devices with an association to the NDGs. NDGs and network devices are processed as a single object group.

When a new record is imported into ACS 5.2, a default description field called Migrated is created.

Multiple-Instance Support

In ACS 5.2, you cannot define different network devices with an overlapping IP address. You may define a specific (or global) prefix for the network device name to avoid duplicates. However, devices that have overlapping IP addresses are reported as duplicates and are not migrated, even though their names are unique. Also, merge between two such instances is not supported.

For example:

Instance = X, network device = AA, IP address = 23.8.23.12, protocol = RADIUS, group = HR

Instance = Y, network device = BB, IP address = 23.8.23.12, protocol = TACACS+, group = HR

In this example, you cannot create a unified device, since the network device AA is from instance X and the network device BB is from instance Y. If the TACACS+ and RADIUS devices are from the same instance, unified device creation is supported.

Devices that are associated to an NDG which was imported in a previous migration instance are associated to the NDG that already exists in ACS 5.2.

NDG

To facilitate migration of the ACS 4.x NDG definitions, an additional NDG hierarchy has been created in ACS 5.2.

During the migration process, you are prompted to enter the name of the hierarchy root that stores the ACS 4.x NDG definitions. The prompt offers a default name of the migrated NDG; you can modify this name as desired.

ACS 4.x contains an unsaved group known as Not Assigned NDG for all the devices that do not belong to any group. The Not Assigned NDG group is created after export to ACS 5.2.

In ACS 4.x, the NDGs contain attributes, such as shared secret and Legacy TACACS+ Single Connect support for the AAA client. However, in ACS 5.2, the NDGs are labels that can be attached to the network device definitions and do not contain data. If a value is set for the shared secret in an ACS 4.x NDG, this value is extracted to set the value for each network device associated with the group.

No similar information is displayed during the export phase.

Import

During the import phase, a new NDG hierarchy is created, with the name as defined in the User Preferences. A root node with name as per the User Preferences, prefixed by All, is also created. All the migrated NDGs are created under this root node.

Multiple-Instance Support

In ACS 5.2, you cannot define two NDGs (hierarchy node) with the same name on one hierarchy root; however, it is possible to define them on different hierarchies. For example, you can define two groups named Engineers, one on the root SJ and the other on the root NY. Multiple-instance support allows you to do one of the following to migrate the NDGs:

Define a different root for each instance and import all the NDGs of the instance under the instance root.

Define one root for all the migrated NDGs; the Migration Utility adds only the unique NDGs to the root. NDGs that already exist are reported as duplicates and are not imported. However, in this case the ID of the already existing NDG is retrieved for association purposes.

To choose either of these options, go to Preferences > User Interface. For each selection, the association between the NDG and the network devices is maintained according to the logic of that selection.

For example, Device ABC (with a unique name and IP address) associated to an NDG SJ is migrated from the first ACS 4.x instance. When you select any of the above two options, ABC is associated to NDG SJ, but SJ can be defined either in the root All or in the specific root Engineers.

Internal User

In ACS 5.2, policy components are reusable objects that can be selected as policy results.

Migration activities related to internal users consist of the following aspects:

Basic User Definition

Multiple-Instance Support

User Data Configuration and User Mapping

User Shell Command Authorization

Shell Exec Parameters

ACS 4.x can contain dynamic users. External databases, such as LDAP, can manage dynamic users, their identities, and other related properties.

Dynamic users are created in the ACS internal database after they are successfully authenticated against external sources. Dynamic users are created for optimization, and removing them does not affect ACS functionality. Dynamic users are ignored by the Migration Utility and are not processed.

Basic User Definition

For each user, the basic definition includes username, password, disable or enable status, and identity group.

Analysis and Export

Some special characters and <space> are not allowed in the username during export. It is reported in the Analysis report if the following characters are used in the username:

<> " * ? { }

Users with a password of fewer than four characters are not exported.


Note User Command Sets is not migrated for users which have apostrophe (`).


The following options are available in the password definitions for internal users:

Internal — Password is stored internally in ACS.

External Database — Password is stored in an external database, and authentication is performed against this database.

Empty Password — VoIP users can be defined by associating them with a group that has the This is a Voice-over-IP (VoIP) group - and all users of this group are VoIP users settings selected. In this case, no password is defined for the user.

Import

Externally authenticated users are not supported in ACS 5.2. The following configuration options are available to define import of such users:

Default authentication password — All externally authenticated users are assigned with this password.

Disabled or Change password — You can select whether such users are defined in ACS 5.2 as disabled or are required to change their password on the next login.

No analysis warnings are displayed for such users, because there could be a large number of them.


Note VoIP is not supported in ACS 5.2. Users associated with a VoIP-enabled user group are reported as part of the analysis and are not exported.


Multiple-Instance Support

Duplicate identification of users from different ACS 4.x instances is based on the username and is reported in the Import report. Only unique users are migrated. There is no support for a name prefix or merge between users' data from multiple ACS 4.x instances.

For example, it is not possible to add an enable password to the user Jeff, if Jeff exists in multiple ACS 4.x instances and the enable password exists only on the instance that was not migrated first.

Users who have a unique username and are associated to a user group are migrated and the association preserved, even if the user group itself was migrated in the same instance as the user or in a previous instance.


Note If the user does not pass migration, user attribute values and policy components such as TACACS+ and Shell attribute values and the Command Set that originated from the user, are also not migrated, even if they are valid.


User Data Configuration and User Mapping

ACS 4.x contains up to five user-defined fields that can be selected for inclusion in the user record. For each such field, a corresponding field name can be defined. In ACS 5.2, these fields are migrated so that equivalent user attributes can be created and then populated for each user.

To configure these fields, select Interface Configuration > User Data Configuration. You must repeat the configuration for each of the five fields.

The field does not contain the following special characters

{ } ' "

Import

In ACS 4.x, you can define multiple field names with the same name. However, in ACS 5.2, user-defined attributes must have unique names. If multiple attributes have the same name, the original name is retained only for the first attribute found. For subsequent attribute, the suffix _1 is added.

For example, if three attributes in ACS 4.x have the name ACS, after import to ACS 5.2, the attribute names are as follows:

First attribute—ACS

Second attribute—ACS_1

Third attribute—ACS_2

Multiple-Instance Support

In ACS 5.2, you cannot define two user attributes with the same name on the identity dictionary. However, you can create a name prefix for each ACS 4.x instance and add the attribute for each instance.

You can select one of the following options to migrate the user attributes:

Define a different name prefix for each instance and import all the user attributes with different names.

Do not define a prefix. This results in unique attributes migration only. Attributes that already exist are reported as duplicates. In this case, the ID of the existing user attribute is preserved for association purposes.

User data for any user is taken only from a single ACS 4.x instance. If the same user exists in another ACS 4.x instance, the user is not imported but the user attributes are migrated with null values. There is a single set of internal user attributes that applies to all users.

For example, you migrate the user, user1 with user attribute A with value x and user attribute B with value y, from first ACS 4.x instance. Then, you migrate the same user, user1 with user attributes C with value z and user attribute D with value w, from the second ACS 4.x instance.

Here, the user user1 from the second instance is not migrated, but the user attributes C and D are migrated with null values. The user user1 in ACS 5.2 will contain the following attributes:

A with value x

B with value y

C with null value from the second instance.

D with null value from the second instance.

The same user can contain attributes from second instance but not the attribute values. You cannot merge user attributes from multiple ACS 4.x instances.

For example, it is not possible to add only the attribute Real Name: Jeffrey to user jeff, if the user already exists in ACS 5.2 (migrated from another ACS 4.x instance) and the attribute Real Name: Jeffrey exists only on the current ACS 4.x instance.

The association between the user and the user attribute is preserved regardless of the migration run (current or previous migration) when the user attribute definition is migrated. A user with a unique username (that can be added in the current run) that is associated with a user attribute that already exists in ACS 5.2 (and was migrated in a previous run of the migration) is associated to the existing user attribute.

In ACS 5.2, every identity attribute that gets added to the dictionary also gets added to all the users, even if the value is blank.

For example, you create user, User1 in ACS 4.x first instance and start the migration utility. Enter the first instance server ID and add server specific migration prefix global1. Migrate the user, User1 with user attributes city, real name and description.

Create user, User2 in ACS 4.x second instance and start the migration utility. Enter the second instance server ID and add server specific migration prefix global2. Migrate the user, User2 with user attributes city, country and state.

After migration to ACS 5.2, user1 will contain the attributes, global1_city, global1_Description, global1_Real Name, global2_city, global2_country and global2_state.

User2 will contain the attributes, global1_city, global1_Description, global1_Real Name, global2_city, global2_country and global2_state.

Here, attributes with prefix global1 should be used for User1 and attributes with prefix global2 should be used for User2.

User Shell Command Authorization

In ACS 4.x, a Shell command set can be embedded in the user record. As part of the migration functionality, this command set is extracted and defined as a shared object. A user attribute contains the name of a command associated with a user that was retrieved from the user record.

User command sets are migrated to shared command sets only if the user is migrated. The name is generated from the username.

Shared command sets are extracted only if the corresponding user was migrated.

Analysis and Export

In ACS 4.x, you can assign a Shell command authorization set on a per-NDG basis where the user record contains pairs of device group names and command set names. This equivalent functionality is not supported in ACS 5.2, and a message is displayed during analysis.

Import

The following user settings are used during import of each user command set:

Command set name format options—Add Prefix | User Name only.

Text for prefix.

Prefix to be added for consolidated objects in addition to the previous prefix—Default is an empty string

The user attribute cmd-set is used to store the name of the ACS 5.2 command set that is migrated from a user definition.

To import a user command set:


Step 1 Create the cmd-set user attribute.

Step 2 For users who have a per-user definition of a command set:

a. If the command set has been consolidated into another record, then proceed to process the next user.

b. Determine the name of the command set as a combination of the username and any defined prefixes.

c. Create the migrated command set.

Step 3 Set the name of the migrated command set in the cmd-set user attribute for the user.


Multiple-Instance Support

In ACS 5.2, you cannot define two command sets with the same name. However, you can create a command set with a name prefix per ACS 4.x instance and migrate the command sets for each ACS 4.x instance.

Thus, you can choose one of the following options to migrate command sets:

Define a different name prefix for each instance and import all the command sets with different names.

Do not define a prefix. Only unique command sets are migrated. The command sets that already exist (migrated in the previous instance), are reported as duplicates.

Shell Exec Parameters

In ACS 4.x, the user record contains shell (exec) TACACS+ Settings. These settings are migrated to ACS 5.2 as attributes of the user record. If one of these attributes is in use for any of the migrated user records, it is created as a user attribute. The value is set in the corresponding attribute in the migrated user definition.

The User Shell attribute values are migrated only if the user is migrated.

Analysis and Export

ACS 5.2 supports the privilege level as a numeric value (0-9999). In ACS 4.x, privilege level is a string field with no validity checks. If the privilege level is not within the valid range, it is reported to the administrator.

This check is not applicable to the enable password, where the privilege level is selected from a valid list. However, an additional analysis verifies that the privilege level in the shell exec settings does not exceed the maximum enable privilege. Custom parameters defined in the shell exec are not supported in ACS 5.2. Invalid idle time and timeout values are reported in the Analysis report.

Import

The shell exec parameters for all the users are collected. If a parameter exists for at least one of the users being migrated, it is migrated as a user attribute. In ACS 4.x, if the shell exec value is defined for each user being migrated, in ACS 5.2, this value is set in a user attribute associated with the user in ACS 5.2. If the attribute is not defined in ACS 4.x, it is left blank in ACS 5.2.

Multiple-Instance Support

The Shell attribute has a fixed name. You cannot create Shell attributes with a name prefix per ACS 4.x instance. Also, you cannot merge the Shell attributes data (values) from multiple ACS 4.x instances.

For example, you cannot add only the attribute Timeout:123 to user jeff, if the user already exists in ACS 5.2 and that Shell attribute is not defined on the user.

The association between a user and the Shell attribute is preserved regardless of the run (current or previous migration) when the Shell attribute definition is migrated.

A user with a unique username (added in the current run) is associated with a Shell attribute that already exists in the ACS 5.2 identity dictionary (migrated in the previous run of the migration) is associated to the existing Shell attribute.

If the same user exists in another ACS 4.x instance, the user is not imported but the user shell attributes are migrated with null values. There is a single set of internal user shell attributes that applies to all users. In ACS 5.2, every user shell attribute that gets added to the dictionary also gets added to all the users.

User Group

In ACS 5.2, the identity group is equivalent to the user groups. However, each identity group is purely a logical container to group sets of users for the purposes of policy processing and selection in rules conditions.

The user group names are migrated and merged into the identity group hierarchy. A new node is created beneath the root node of the identity hierarchy and under this node, all the migrated user groups are placed in a flat structure. You are prompted to define the name of this node. A default name is also presented.

In ACS 4.x, 500 user groups are created by default, and these groups can be edited by the administrator. In ACS 5.2, only the user groups that are being utilized and referenced from user or MAC definitions are migrated.

To keep the association between the users and user groups (the identity groups), you must first export (and import) the user groups, followed by the internal users with associations to those user groups.

This section contains:

Analysis and Export

Multiple-Instance Support

Analysis and Export

A user group that does not contain any internal users or MAC definitions is not exported. It is reported to the administrator that such user groups have not been migrated. In addition, some special characters are not allowed in the group name during export. This will be reported in the Analysis report and the export will not proceed if the following characters are used in the group name:

{ } | ' " = :

Import

During import, a new identity group node, with a name defined in the User Preferences, is created under the root node of the identity group hierarchy. The default name is Migrated Group. All migrated user groups are created in a flat hierarchy under this newly created node.

In ACS 4.x, each user was associated to a single group. To keep the association between the users and user groups (the identity group) the user groups are imported first, followed by the internal users with associations to the user group.

Multiple-Instance Support

In ACS 5.2, you cannot define two identity groups with the same name on one hierarchy root. However, you can define them on different hierarchies.

For example, you can define two groups named Engineers, one on the root NY and the other on the root SJ. The multiple-instance support allows you to select one of the following options to migrate the groups:

Define a different root for each instance and import all the user groups of the instance under the instance root.

Define one root for all the migrated groups. The Migration Utility adds only unique groups to the root. Groups that already exist are reported as duplicates and are not imported. However, the ID of the already exiting user group is retrieved for association purposes.

To select either of the options, go to User Preferences. The association between user group and users is maintained according to the logic of that selection.

For example, the user john (unique username) is associated to the group Management, which was migrated from a previous run of an ACS 4.x instance. On any option selected, john is associated to the group Management, but Management is defined in the root All or in the specific root Engineers.

User Group Policy Components

In ACS 4.x, most of the policy-related authorization data is embedded within the user group definitions, whereas in ACS 5.2, this data is defined as shared objects.

Data is migrated only from the groups that are in use. The following data is extracted from the group data:

TACACS+ shell command authorization set is migrated to a command set.

TACACS+ shell exec (+max privilege level) is migrated to a shell profile.

This section contains:

Group Command Set

Group Shell Exec

MAC Addresses and Internal Hosts

The names of the command sets extracted from the users are stored in a user attribute. No similar action is performed when the data is extracted from the user groups. The multiple-instance support for the groups' command sets is similar to the users' command sets.


Note Group command sets are migrated only when the groups are migrated.

Analysis is performed on all groups that are determined to be in use and that are associated either with users or MAC addresses. The analysis verifies that the following values entered in ACS 4.x are in a valid range for the corresponding ACS 5.2 object:

Timeout: 0-9999

Idle Time: 0-9999

Privilege Level: 0-15

The analysis also verifies that the new Default Privilege Level value is not higher than the maximum value. If a group to be migrated has custom attributes defined, it is not migrated to ACS 5.2 and a warning is displayed.

Import

The following user settings are used during import of the group shell exec:

Shell profile name format. Options available are:

Add prefix

Group name only

Text for prefix.

Prefix to be added for consolidated objects in addition to the prefix above. The default is an empty string.

The import process is performed for each shell exec that is not consolidated into another object. The name of the ACS 5.2 object is determined based on the user settings and the created shell profile.


Note Group Shell attributes are migrated only when the group is migrated.


Multiple-Instance Support

Group Shell attributes are migrated to shared shell profiles and the name is generated from the group name.

In ACS 5.2, you cannot define two shell profiles with the same name. However, you can create shell profiles with a name prefix per ACS 4.x instance, and thus you can add shell profile for each instance. With the multiple-instance support, you can select one of the following options to migrate the shell profiles:

Define a different name prefix for each instance and import all the shell profiles with different names.

Do not define a prefix. This results in uniquely named shell profile migration. Shell profiles that already exist are reported as duplicates.

MAC Addresses and Internal Hosts

In ACS 4.x, support for authentication based on MAC address is as follows:

Define the MAC address as an internal username with a Password Authentication Protocol (PAP) password that is identical to the username. The user is migrated into the internal user database and there is no need for additional support for MAC addresses.

Define the MAC address in the NAP table as part of the authentication policy. Within the authentication policy, you can configure to authenticate the MAC address with the ACS internal database. You can then provide a list of MAC addresses and a corresponding identity. The MAC addresses are migrated to the corresponding records in the internal host's database.

In ACS 5.2, you can define additional attributes to be associated with the hosts, as is done for the users. However, in ACS 4.x, there is no additional data associated with the MAC definitions and hence no additional attributes are required for migration. However, the association with the identity group is retained.

Analysis and Export

You can enter MAC addresses in multiple formats, but they are always stored in 12-34-56-78-90-AB format. However, in ACS 4.x it is possible to include a wildcard in the address; for example, 12-34-56-78*.

In ACS 5.2, you cannot include a wildcard in the MAC address and you must provide a specific MAC address. If you do not do so, it is reported during the analysis. In ACS 5.2, you can migrate only the first MAC address found, along with its associated user group.

For example:

NAP A has the following MAC addresses: 1-2-3-4-5-6 Group 200, 2-3-4-5-6-7 Group 3

NAP B has the following MAC addresses: 1-2-3-4-5-6 Group 77, 2-3-4-5-6-7 Group 3

Here, only the NAP B MAC address 1-2-3-4-5-6 is migrated. It is associated to group 200 (the first group that is extracted), and not to group 77. Also, MAC address 2-3-4-5-6-7 is not reported because it has the same group in both NAPs in which it is defined.

Multiple-Instance Support

In ACS 4.x, duplicate MACs are identified based on the MAC address and are reported in the Import report. Only unique MAC addresses are migrated. There is no support for name prefix. Unique MAC addresses that are associated to a user group are migrated.

The association is preserved, regardless of whether or not the user group itself was migrated in the same instance as the MAC address or in a previous instance.

Shared Shell Command Authorization Sets

In ACS 4.x, the Shell command authorization set can be defined as shared objects, as part of the device administration. Such objects are migrated to the command sets. The name and the description of each object is the same as in ACS 4.x.

Multiple-Instance Support

In ACS 5.2, you cannot define two command sets with the same name. However, you can create them with a name prefix per ACS 4.x instance, and thus you can add a command set for each instance. Thus, with the multiple-instance support, you can select one of the following options to migrate the Shared command sets:

Define a different name prefix for each ACS 4.x instance and import all the command sets with different names.

Do not define a prefix, resulting in a uniquely named command set migration. Command sets that already exist are reported as duplicates.

Shared DACL Objects

In ACS 4.x, a shared downloadable access control list (DACL) can be defined as a shared object to be referenced from the application. A shared DACL consists of a set of ACL contents, where each ACL is associated with a specific Network Access Filtering (NAF) selection. When the object is referenced, the actual ACL that is utilized depends on the NAF condition that matches first.

ACS 5.2 contains the authorization policy that results in the selection of a DACL from an authorization profile. Therefore, each ACL contained within an ACS 4.x shared DACL is mapped to a separate DACL in ACS 5.2.

The created object name is analyzed and the following analysis issues, if present, are reported:

If the object name exceeds 32 characters, the report shows that the final object name is truncated to 32 characters.

All the object names that contain the following invalid characters:

{ }' "

The invalid characters may come from the shared DACL part or the ACL part of the name. If the DACL name contains invalid characters, the report shows all the combinations of the ACL.


Tip If the ACL name is used, multiple ACL records could be created on ACS 5.2 with the same name. You should utilize this option only if you are sure that the ACL name is unique or there are duplicate ACLs and you want to import only one.


No analysis is required for the ACL definition.

Import

You cannot create multiple DACLs with the same name. If you do so, it is reported in the Import report. This occurs when you use the ACL option for the DACL name to migrate multiple shared ACLs that contain the same ACL.

Multiple-Instance Support

In ACS 5.2, you cannot define two DACLs with the same name. However, you can create DACLs with a name prefix per ACS 4.x instance and thus add DACLs for each instance. With the multiple-instance support, you can select one of the following options to migrate the DACLs:

Define a different name prefix for each instance and import all the DACLs with different names.

Do not define a prefix. Only uniquely name DACLs are migrated. DACLs that already exist are reported as duplicates.

Shared RACs

In ACS 4.x, you can define a shared profile component that contains RADIUS Authorization Components (RACs) and defines a set of RADIUS attributes and values that are to be returned in an authorization response. These shared objects map the direction to the authorization profiles that are defined in ACS 5.2.

In ACS 4.x, an attribute is identified in the GUI as a combination of the vendor name and the attribute name. In ACS 5.2, it is defined as a combination of the dictionary and attribute name. Internally, the vendor or dictionary and attribute are identified by IDs which are, in turn, the values used while forming the RADIUS response.

Analysis and Export

Some special characters are not allowed in the shared RAC during export. It will be reported in the Analysis report if the following characters are used in the shared RAC:

{ } ' "

In ACS 4.x, the Microsoft vendor attributes can be included in a RAC, but values cannot be set, and a fixed string of <Value set by ACS> is displayed. The following Microsoft vendor attributes can be selected:

MS-CHAP-MPPE-Keys (12)

MS-MPPE-Send-Key (16)

MS-MPPE-Recv-Key (17)

In ACS 5.2, you cannot configure these attributes, but they are added to the profile as required, depending on the type of authentication being performed and the corresponding required response. If these attributes are defined in ACS 4.x, the Analysis report states that they have not been migrated; although the RAC that contains them was migrated.

Import

You can optionally configure a prefix to be added to the name of all the migrated RACs. In ACS 5.2, attributes are included in an authorization profile if they meet the following conditions for the relevant properties:

Direction: OUT or BOTH

Available: TRUE

The import process verifies that these conditions are met for all the attributes to be included in a profile, and any discrepancy is reported in the Import report.

Multiple-Instance Support

In ACS 5.2, you cannot define two RACs with the same name. However, you can create RACs with a name prefix per ACS 4.x instance and add RACs for each instance. With the multiple-instance support, you can select one of the following options to migrate the RACs:

Define a different name prefix for each instance, and import all the RACs with different names.

Do not define a prefix. Only uniquely named RACs are migrated. RACs that already exist are reported as duplicates.

RADIUS VSAs

The dictionary and its content (the attribute definitions) are an important and core part of ACS 4.x. The dictionary defines the attributes specified by the IETF for the RADIUS protocol, and it is augmented by the Vendor Specific Attributes (VSAs) defined by different device vendors. VSAs are allocated a structured name space within the value of one of the IETF attributes (Attribute 26).

The majority of the used attributes are predefined in the dictionaries shipped with ACS. However, as vendors expand the capabilities of their devices, new VSAs are added.

If you do not wish to wait for the next release of ACS to get the updated dictionaries, you can use the Command Line Utility to define new dictionary slots for the new vendors, to augment the attributes of an already existing vendor in the dictionary, or to update already defined VSAs (for example, with additional enumeration values).

During migration, the dictionary is iterated to identify the missing attributes in ACS 5.2 for each vendor. There are two possible cases during this identification process:

If the vendor does not exist in the ACS 5.2 dictionary, all the vendor attributes are migrated.

If the vendor exists in the ACS 5.2 dictionary, only attributes that are not defined in ACS 5.2 are migrated.

For the Cisco Airespace attribute Aire-QoS-Level(2), the description of the enumerated values is different between ACS 4.1.x and ACS 5. Since the numeric value gets migrated, there is no difference in the response sent when using RACs that include this attribute and the same numeric value will be sent in the response. However, the string presented in the ACS GUI for this value is different.

For example, in ACS 4.1.x the value of 1 is displayed as Silver whereas in ACS 5.2 this is displayed as Gold.

Table 6-17 shows the mapping of Aire-QoS-Level (2) values between ACS 4.1.x and ACS 5.2.

Analysis and Export

The analysis phase for the RADIUS VSAs focuses on merging the dictionary content of ACS 4.x with the dictionary content of ACS 5.2. There are two cases for analysis:

Generally, for ACS 4.x supported vendors, the dictionary in ACS 5.2 is more up-to-date. However, you may have modified some ACS 4.x vendor dictionaries to include new VSAs, or to modify the existing VSAs (for example, new enumeration values). The migration behavior is as follows:

An attribute defined in ACS 5.2 is not altered during migration. A warning is displayed for such attributes.

An attribute not defined in ACS 5.2, but present in ACS 4.x, is migrated.

The vendors that are imported by you into ACS 4.x, and are not present in ACS 5.2, are migrated without any analysis warning.


Note Difference between ACS 4.x and ACS 5.2 VSA attributes (profile, name, type) are reported in the Analysis report.


Import

All the exported VSAs are imported to ACS 5.2.

EAP-Fast Master Keys and Authority ID

In ACS 5.2, you can preserve support for all objects (users or devices) that authenticated on ACS 4.x. Therefore, all the master keys and the authority ID from ACS 4.x are migrated.

The master keys in ACS 4.x have a schema that is different from that of ACS 5.2, and they are migrated to different IM objects. ACS 4.x stores the authority ID per node while ACS 5.2 stores the authority ID only in the primary database and then applies it to the entire deployment.

Creation Time

Expiration Time (TTL)

Expiration Time

The Expiration time is calculated by adding the Current time and the Retired master key TTL.


The expiration time is calculated as follows:

1. From the list of keys in the database, the tail key is checked to determine whether or not it has expired.

2. Key creation time is saved as KeyCtime for the current key.

3. Current time is calculated by Calling Time(NULL).

4. TTL is taken for the key stored in AuthenConfig > EAP-FAST.

5. The Expiration time is calculated by adding the Current time and the Retired master key TTL.

The master key TTL unit is represented as follows:

Minutes: 1, Hours: 2, Days: 3, Weeks: 4, Months: 5, Years: 6

For example, if the active master key TTL is selected as 1 month, it equates to 1 * 30 * 24 * 3600.

Analysis and Export

No analysis is done. Expired keys are not migrated.

Import

In ACS 5.2, the objects are added to the Master Key table and are not available through the GUI. The authority ID is migrated to the EAP-FAST global settings.

Multiple-Instance Support

In ACS 5.2, you cannot define two master keys with the same ID; therefore, only unique master keys are migrated from multiple instances of ACS 4.x.

In ACS 5.2, the authority ID is stored as a global EAP setting and not stored per node or instance. Hence, it can be migrated only from one instance.

Analysis and Export of ACS 4.x Data

Choose option 1 in the Migration Utility to run AnalyzeAndExport. Refer to Example 6-1. The Analyze and Export phase runs on the ACS 4.x migration machine by using data restored from the backup of the ACS 4.x source machine. The AnalyzeAndExport Summary Report lists the total:

Detected objects.

Issues reported for each object.

Objects that can be migrated.

Information on issues for each object.

Data to be consolidated. Refer to Consolidating Data.

The Analyze and Export phase can be run multiple times to make configuration changes between analysis cycles. For example, you might have overlapping IP addresses for network devices. You can use the ACS 4.x application to correct this issue. Once you correct the issue, you can rerun the Analyze and Export phase and proceed to the Import phase. Refer to Overlapping IP Addresses.

Refer to "ACS 5.2 Attribute Support in the Migration Utility," for a list of the attributes that are migrated.

Consolidating Data

The consolidation process occurs in the Analysis and Export phase and:

Analyzes the created shared objects.

Identifies the objects that are identical.

Ensures that duplicate ACS 4.x objects are collapsed to a single object which is migrated to ACS 5.2. This object can then be referenced by ACS 5.2 policies.

For example, the Analysis report might show multiple command sets that appear to be different, but are actually the same command set. This might be because of the command set shortcuts, such as show or sho. In ACS 5.2, you can define polices such that they incorporate the migrated command set information. Refer to the User Guide for Cisco Secure Access Control System 5.2 for more details on ACS 5.2 policies.

Consolidates the following:

User and user group command set into a command set profile.

Group shell exec into a shell profile.

Issues Resulting from the Analysis and Export Phase

Not all data entities can migrate from ACS 4.x to ACS 5.2. The Analysis and Export phase might reveal issues such as overlapping IP addresses for the network devices.

Another issue is that the ACS 4.x IP address network device definitions could include wildcards and ranges. ACS 5.2 uses a standard subnet mask representation. Therefore, the network device definitions might not be compatible.

The Analysis and Export reports detail these issues. You can address these issues in the ACS 4.x application and subsequently rerun the analysis and export. You can rerun this process as many times as required. After you fix the issues, you can import the exported data to the ACS 5.2 machine.

Importing the ACS 4.x Data to ACS 5.2

Choose option 2 in the Migration Utility to run Import. Refer to Example 6-1. This phase imports the ACS 4.x data export file created in the Export phase.

The import process can take a long time if you migrate data from a large database.


Note If the ACS 5.2 import fails, restore your ACS 5.2 database.

Migrating Multiple Instances

Choose option 4 in the Migration Utility to import another ACS 4.x instance. Refer to Example 6-1. You can import multiple ACS 4.x instances to ACS 5.2. Example 6-6 shows the prompts that appear if you decide to migrate multiple instances.

Example 6-6 Importing Multiple Instances

Would you like to migrate another ACS4.x server? [no]
yes
Enter ACS 4.x Sever ID:
--------------------------------------------------------
 
   

After you enter the server ID or hostname of another ACS 4.x instance, the whole migration process starts again. In this way, you can migrate several ACS 4.x instances to ACS 5.2.

Migration Impact on Memory and Performance

Data export is performed from the ACS 4.x migration server and not directly from the ACS 4.x production server or source server. Therefore, the migration has no impact on the performance of the ACS 4.x production server. The Migration Utility can be run on a standard PC environment.

During the import of the migrated data, the ACS 5.2 server should be idle and not processing any AAA requests.

Printing Reports and Report Types

Choose option 3 in the Migration Utility to print full reports and summary reports to a CSV file. Refer to Example 6-1. The config folder in the migration directory contains the Migration Utility reports. In the config folder, a new folder with the same name as the server ID is created for each
ACS 4.x server that you migrate.

For example, if the server ID is test1, a folder test1 is created under the config folder and it contains the Migration Utility reports. The report name has the server ID attached. This section contains:
