Release Notes for Data Migration Assistant (DMA) Release 7.0(1a)
September 16, 2008
This document comprises the new features that are included and caveats that are resolved in Data Migration Assistant (DMA) Release7.0(1a).
These release notes discuss the following topics:
Data Migration Assistant (DMA) Release 7.0(1a) collects application data from a Cisco Unified Communications Manager Releases 4.1(x), 4.2(x) and 4.3(x) system for upgrade to Cisco Unified CM Release 7.0(1a). DMA exports data in the current Windows based system (with SQL Server database) that later will get imported to the Linux based system (with Informix database).
DMA also collects application data from a Cisco Emergency Response (CER) 1.3 system for upgrade to CER 7.0.
DMA saves the data that it exports in a tape archive (.tar) file in a location that you specify.
In addition to creating an export, DMA also performs a set of migration compatibility tests (data validation) on the exported Unified CM 4.x data
•If DMA discovers issues, either in the export itself, or in the data validation, DMA may report some type of "Failure." Do not consider such a message to be alarming.
•Even when DMA completes successfully, but especially if any "Error" or "Warning" occurs, the user should examine the generated messages. These messages may be
–Simply information about auto-data-correction that will be performed in the migration.
–Alerts to let you know the problems that DMA encountered as it attempted to check the data.
Generally, these problems require user expertise to determine how best to alter the data to remove the migration incompatibility.
Note You must install and run DMA Release 7.0(1a) on the Cisco Unified Communications Manager publisher server before you upgrade to Unfied CM 7.0(1). If you make any configuration changes to Cisco Unified Communications Manager after you run DMA, the system does not retain these changes when you upgrade.
Note Do not consider the DMA Export a substitute for a system backup. You cannot use it to restore your Cisco Unified Communications Manager system in the unlikely event that you are unable to complete your upgrade.
The following section contains important information to help you get started with Data Migration Assistant Release 7.0(1a).
Upgrades That Are Supported
Supported upgrade paths comprise:
•Unified CM releases 4.1(3), 4.2(3), 4.3(1) and 4.3(2) to Unified CM 7.0(1)
•CER 1.3 to CER 7.0
Note DMA 7.0(1a) does not support upgrades from Unified CM releases 5.1(x), 6.0(x), or 6.1(x).
Run DMA Early
Note Be aware that it is important that you run DMA early - possibly as early as weeks before the actual upgrade window to allow time for you to fix any non compliant data.
A successful DMA run does not completely prepare you for migration and upgrade.
To understand critical tasks that must be completed, Cisco recommends that you read the "Before You Begin" section of the Data Migration Assistant User Guide Release 7.0(1a) before you use DMA to export data from the Windows system.
To understand critical upgrade tasks that must be completed, Cisco recommends that you refer to Upgrading to Cisco Unified Communications Manager Release 7.0(1) from Cisco Unified Communications Manager 4.x Releases.

Cisco Security Agent (CSA)
Before the DMA export begins, check the system CSA version by right-clicking the red CSA flag in the systray and, from the options that display, click About.
If the CSA version equals
•Less than 2.0(5), DMA stops CSA automatically during the export.
•Less than 3.0(3) but greater than 2.0(5), you must manually disable CSA before you run DMA.
•3.0(3) or higher, CSA can remain enabled while DMA runs.
Completion Status Recognition
DMA completion can reflect four possible outcomes:
•Export Success & Validation Success
Note If your DMA run results in one of the following three outcomes, you must fix the inconsistencies and rerun DMA.
•Export Success & Validation Success but with Warnings
•Export Success & Validation Failure
You can access the DMA log files from the final status window. You can use them to see what needs to be fixed.
Data Migration Assistant 7.0(1a) generates a configuration file (platformConfig.xml) that can assist you in performing an upgrade of the first node to Cisco Unified Communications Manager 7.0(1) from supported releases of Cisco Unified CallManager 4.x. During the upgrade, the configuration file prepopulates several fields, including domain name, IP address, primary DNS, secondary DNS, and NTP server.
•platformConfig.xml extracts info from the CM 4.X servers to automate some steps during Linux installation on the publisher server.
•platformConfig.xml gets stored in the same location as the DMA tarball if the storage location is on local or network drives.
•platformConfig.xml gets stored in D:\DMA\ if the DMA tarball storage location is on the tape drive.
•Customer must copy platformConfig.xml to a USB key and plug in this USB key on the publisher server during the Linux installation.
When this platformConfig.xml is used during W1 install, the "Apply a Patch" screen gets skipped
The Linux install screen populates input data that is extracted from the platformConfig.xml
To use the configuration file, copy the platformConfig.xml file to a USB key and place the USB key into the Cisco Unified Communications Manager first node before you boot the server with the Cisco Unified Communications Manager 7.0(1) DVD.
If you choose to store the DMA tar file on a network directory or local directory, DMA stores the platformConfig.xml in the same directory. If you choose to store the DMA tar file on a tape drive, DMA stores the platformConfig.xml in D:/DMA.
Note Cisco requires that you use USB keys that are compatible with Linux 2.4. Cisco recommends that you use USB keys that are preformatted to be compatible with Linux 2.4 for the configuration file. These keys have a W95 FAT32 format.
Installation/Upgrade (Migration) Considerations
To use the configuration file that Data Migration Assistant generates to prepopulate fields during an upgrade to Cisco Unified Communications Manager 7.0(1) from supported releases of Cisco Unified CallManager 4.x, copy the platformConfig.xml file to a USB key before you boot the server with the Cisco Unified Communications Manager 7.0(1) DVD.
Cisco Unified CM Target Version Checking
DMA generates DMABackupInfo.inf and includes this file in the tarball, as in the previous releases.
TargetCCMVersion = X.Y.Z (for example 7.0.1) indicates the Unified CM version with which this DMA tarball is compliant.
In Linux installation application, additional logic got added to verify that TargetCCMVersion matches the Unified CM version that you are installing.
TargetCCMVersion gets saved in the DMABackupInfo, inf file in the DMA tarball.
This provides a hook for the Linux installation application to verify whether the DMA tarball is generated by the proper DMA version.
Unified CM Target Version Gets Saved in the DMABackupInfo.inf
DMA export saves the target Unified CM version in the DMABackupInfo.inf file:Sample in the DMABackupInfo.inf:CCMVersion= 4.1.XTargetCCMVersion = X.Y.Z
For example, for DMA 7.0(1a), the target Unified CM upgrade version equals release 7.0(1). So, this field displays 7.0.1, which is the Unified CM version, not the DMA current version, in case the version numbers get out of sync in future releases.
This means that if a Cisco Unified CM 7.0(1) respin becomes a reality in the future, the logic will work, and the customer can use DMA 7.0(1a)) to upgrade to the Unified CM Release 7.0.1 respin release.
Support For Mapped Network Drive
DMA can create the DMA tarball in a mapped network drive that is defined in the Storage Location Window.
Select Network Directory Option and provide the path (for example, M:\export), userID, and password.
The drive letter gets translated to Windows UNC frormat (for example, 10.89.75.11\c$\export)
The system renamed Network Directory to Windows Network Directory.
Exporting RTMT Reports
DMA exports RTMT Reports data files that reside in C:\CiscoWebs\Service\RTMTReports\. DMA stores the files in the \serv\rtmt directory of the DMA TAR file.
Exporting Quality Reporting Tool (QRT) Reports
DMA exports QRT files to the DMA TAR file that exist in the location that is specified in the Log File field in the Service Parameter Configuration window for the Cisco Extended Functions service. The specified log file path must reside on the C:\ drive. If the path does not exist on the C:\ drive, DMA does not export the QRT reports, so the administrator must export the reports manually.
Note If the Cisco Extended Function Service is running, the last (current) QRT file that is being used by this service cannot be exported. This is expected behavior, and is not an error.
You can uninstall DMA by following these steps:
Step 1 From the Start menu, click Settings > Control Panel > Add/Remove Program.
Step 2 Locate Cisco Data Migration Assistant in the list of programs and click Remove.
This removes IDS, IDS Client SDK (if it exists), DSNs, and the DMA application
Step 3 When the removal completes, reboot the server as prompted.
You will see IDS uninstall prompts that will be auto-selected for you.
In the Add/Remove Programs list, the Informix Dynamic Server 10.00 and corresponding SDK Client specify no longer selectable.
Proper Return Code Sent To the DMA Framework
During DMA export and validation phases, the DMA framework launches separate processes to invoke the underlying component .exe files to export or validate the Unified CM database, directory, CAR, or CER data. When a fatal error exists in the data export or data validation, the logic returns failure to the DMA framework instead of continuing.
By using this information, the framework can determine whether fatal issues are encountered and whether DMA should be aborted.
Unified CM Database, CAR, CER Components
Exportdb.exe gets used to export and validate Unified CM, CAR, and CER databases. The return codes from the exportdb.exe follow:
•0 - Indicates success, DMA framework continues
•1 - Indicates warning, DMA framework continues but display proper warning messages on the status page
•-1 - Indicates failure. DMA framework halts.
During an upgrade, the Linux install application determines whether a platformConfig.xml file exists in the customer USB key. If it exists, the data gets read and populates in the UI. Default values gets used for data that is not found in the platformConfig.xml.
What Gets Migrated via DMA When Unified CM Gets Integrated Into a Corporate LDAP Store
The DirExport is the part of DMA that extracts user data from the directory and creates CSV files of that data. The CSV files get used to populate the database. All the user information gets migrated from the directory to the database.
When you upgrade from Cisco Unified CM 4.x to Cisco Unified CM 5.x or later, the following get migrated.
This section contains information about the caveats that get resolved by this release of DMA and information about how to create your own list of resolved and open caveats.
