Release Notes for Data Migration Assistant Release 7.1(2)
Updated June 22, 2009
This document comprises the new features that are included and caveats that are resolved in Data Migration Assistant (DMA) Release 7.1(2).
These release notes discuss the following topics:
•Important Notes, including
Data Migration Assistant (DMA) Release 7.1(2) collects application data from Unified CM Releases 4.1(3), 4.2(3), 4.3(1), and 4.3(2) system for upgrade to Cisco Unified Communications Manager Release 7.1(2). DMA exports data in the current Window based system (with SQL server database) that later gets imported to the appliance-based system (with Informix database).
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, you should examine the generated messages. These messages may comprise
–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 to alter the data to remove the migration incompatibility.
Note You must install and run DMA Release 7.1(2) on the Cisco Unified Communications Manager publisher server before you upgrade to Cisco Unified Communications Manager Release 7.1(2). 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 cannot complete your upgrade.
The following sections include important information that you should know prior to upgrading to DMA 7.1(2).
Before You Begin
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 to fix any noncompliant data.
A successful DMA run does not completely prepare you for migration and upgrade.
To ensure that you 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 7.1(2) before you use DMA to export data from the Windows system.
To understand critical upgrade tasks that must be completed, Cisco also recommends that you refer to Upgrading to Cisco Unified Communications Manager Release 7.1(2) from Cisco Unified Communications Manager 4.x Releases.

Cisco Security Agent
Before the DMA export begins, check the system Cisco Security Agent (CSA) version by right-clicking the red CSA flag in the systray and, from the options that display, click About.
If the CSA version is:
•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 reflects 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. Use them to see what needs to be fixed.

New and Changed Information for Data Migration Assistant 7.1(2)
The following sections contain information that is new or changed for this release of Data Migration Assistant:
Data Migration Assistant Enhancements
Cisco Unified Communications Manager Release 7.1(2) includes the following Data Migration Assistant (DMA) enhancements. For more details, refer to the documents Data Migration Assistant User Guide 7.1(2) and Upgrading to Cisco Unified Communications Manager Release 7.1(2) from Cisco Unified Communications Manager 4.x Releases:
•The platformConfig.xml file that is generated by DMA supports upgrades for the first node (publisher database server) as well as for the subsequent nodes (subscribers). DMA provides a window where you can make detailed configuration specifications. Enter data at the DMA window Export > Answer File Generator.
•DMA provides a window where users can customize the behavior of DMA by specifying which types of logs to include in the output file. Enter data at the DMA window Export > Custom Options.
•DMA explicitly lists the pre-DMA export tasks. DMA provides both information and the automation of pre-export tasks, when possible, to ensure that the user knows what tasks to complete before DMA is run. Enter data at the DMA window Export > Pre-Export Tasks.
•DMA supports the generation of a license file upon successful DMA validation. The user can upload this license file to Cisco CCO to get the actual license file ready for use. Go to the DMA window Export > Storage Location and specify a local directory destination for the license file licupgrade.lic Specify the destination in the Path Name text box of the window Destination Option for License File field.
•DMA provides a window where users can customize the CAR database export process. If the CAR database is installed, select the desired settings at the DMA window Export >Custom Options.

Effects on CAR Data When You Upgrade Cisco Unified Communications Manager by Using Data Migration Assistant
By default, the CAR database will not get migrated by Cisco Data Migration Assistant 7.1(2). To migrate the CAR database, go to the Export > Custom Options window and adjust the settings. If you are migrating the CAR database, Cisco recommends that you purge the CAR data before running the Data Migration Assistant (DMA). Purging the CDR data speeds up the migration process and decreases the size of the DMA TAR file.
Note Make sure that you purge any CAR records that are older than 180 days.
The Cisco Unified Communications Manager installation program limits the time in which CAR records migrate from the DMA TAR file to the CAR database on the upgraded system. By, default, the time limit that is allotted for the CAR component gets set to 60 minutes. To adjust the default settings, go to the Export > Custom Options window. To facilitate migration of more data, consider the following information:
•Data migration starts with the migration of billing records from the tbl_billing_data CSV file into the tbl_billing_data table of the CAR database. Data migration starts from the latest record and proceeds toward the oldest record in the CSV file. The billing data migration stops when no more billing records remain to be migrated or when the 60-minute time limit is reached, whichever occurs first.
•After the billing data migration, if time remains in the preallotted 60 minutes, CAR proceeds with migration of error records from the tbl_billing_error CSV file into the tbl_billing_error table of the CAR database. Data migration starts from the latest record and proceeds toward the oldest record in the CSV file. For each error record that is migrated, CAR migrates the data that corresponds to the error_record_id that exists in the tbl_error_id_map CSV file into the tbl_error_id_map table of the CAR database. This action ensures that error record migration stays consistent with data in the tbl_error_id_map. The migration process continues until no more data remains to migrate or until the 60-minute time limit gets reached, whichever occurs first.
•Whenever the time limit gets reached, CAR data migration stops, and the tbl_system_preferences of the CAR database get updated to reflect the data that is present in the upgraded system database.
Note If you upgrade from Cisco Unified Communications Manager 4.x, Cisco Unified Communications Manager saves the content of the Cisco Unified Communications Manager 4.x CAR database to CSV files. The Cisco Unified Communications Manager 4.x CAR database includes part of the CDR information. The Cisco Unified Communications Manager 4.x CDR database stores the complete information about CDRs. This database does not migrate. The Data Migration Tool uses the CAR database CSV files to migrate the CAR database. The system stores the CSV files in the /common/download/windows/car directory. The system stores the pregenerated reports in the /common/download/windows/pregenerated database. Because no corresponding CDR database exists in Cisco Unified Communications Manager 5.x and later releases, the complete CDR data does not migrate to the Cisco Unified Communications Manager 5.x or 6.x system. The Cisco Unified Communications Manager 5.x and 6.x CAR database schema gets extended to contain complete CDR information, but only for the new CDRs that the Cisco Unified Communications Manager 5.x and 6.x systems generate.

Ensure CAR Administrator Privileges Are Restored After Upgrade
When you use DMA to upgrade Cisco Unified Communications Manager, CAR users no longer have CAR administrator privileges after the upgrade and become standard end users. You must reset the CAR administrator privileges after the upgrade. Refer to the "Configuring CAR Administrators, Managers, and Users" section in the CDR Analysis and Reporting Administration Guide for more information on how to configure CAR administrators.
