Data Migration Assistant User Guide
This document describes the Data Migration Assistant (DMA), explains how to install and use it, and provides related information.
Use this document if you are running Cisco Unified CallManager 4.0 or 4.1 and are ready to upgrade to Cisco Unified CallManager 5.0.
This document includes the following topics:
Overview of DMA
DMA migrates data for Cisco Unified CallManager, as specified in the following sections.
DMA assists you with the first step in migrating Cisco Unified CallManager 4.0 or 4.1 data to Cisco Unified CallManager 5.0 by backing up Cisco Unified CallManager 4.0 or 4.1 data in a format that Cisco Unified CallManager 5.0 can read. Cisco Unified CallManager 4.0 and 4.1 run in a Windows environment, and Cisco Unified CallManager 5.0 runs in a Linux environment, so DMA exports Windows-based data to a format that Linux can import. The Cisco Unified CallManager 5.0 installation process converts the backed up data as needed for Cisco Unified CallManager 5.0, which completes the data migration.
DMA saves the data that it exports in a tape archive (tar) file in a location that you specify.
You must install and run DMA on the Cisco Unified CallManager publisher server before you upgrade to Cisco Unified CallManager 5.0. If you make any Cisco Unified CallManager configuration changes after running DMA, the system does not retain these changes when you upgrade.
In addition to exporting Cisco Unified CallManager data, DMA exports data for these related applications:
•Cisco Unified CallManager Attendant Console (AC)
•Cisco Extension Mobility (EM)
•CDR Analysis and Reporting (CAR)
•Certificate Authority Proxy Function (CAPF)
•Certificate Trust List (CTL)
•International Dial Plan (IDP)
DMA does not export this information:
•Custom Music on Hold (MOH) files—You must reapply these files after you upgrade to Cisco Unified CallManager 5.0.
•TFTP phone load files—You must reapply these files after you upgrade to Cisco Unified CallManager 5.0.
•Files on Cisco Unified CallManager subscriber servers—Subscriber servers obtain required information from the publisher server as part of the Cisco Unified CallManager upgrade process.
If you do not have DMA software on a disk, perform the following steps to download it to the Cisco Unified CallManager publisher server. Only a registered user of Cisco.com can download this software.
Step 1 Go to this URL:
Step 2 Select DMA file.
Step 3 Follow the onscreen prompts and provide the required information to download the software.

Table 1 Procedures to Follow Before Running DMA
Use the Cisco Unified CallManager Backup and Restore Utility to back up your data. You can use the BARS backup to fall back to your current software version, if necessary.
Refer to the appropriate version of Cisco Unified CallManager Backup and Restore Utility Administration Guide and related documentation at this URL:
Cisco recommends that you use the Cisco Unified CallManager Upgrade Utility to verify that your system is in a good state before the upgrade
Refer to the appropriate version of Using Cisco Unified CallManager Upgrade Utility at this URL:
To back up CAR data, ensure the CAR plugin is installed on the publisher server
See the "Migrating CAR Data" section.
If you use Cisco Unified CallManager Attendant Console, ensure the required files are present on the publisher server.
Copy CAPF data from the subscriber servers to the publisher server.
Migrating CAR Data
Before you can back up Cisco CDR Analysis and Reporting (CAR) data, you must ensure that the CAR plugin is installed on the publisher server. If the CAR plugin is not installed, navigate to Application>Install Plugins and install the CAR plugin. For more information, see the Cisco Unified CallManager Administration Guide or the Cisco Unified CallManager Serviceability Administration Guide.
Note If you do not have to carry over your CDR records to Cisco Unified CallManager 5.0, Cisco recommends that you purge the CDR records before you run DMA.
Migrating Cisco Unified CallManager Attendant Console Data
If you use Cisco Unified CallManager Attendant Console, make sure that the following files exist on the publisher server before you run DMA. If the files do not exist on the publisher, copy them to the publisher from the subscriber server before you run DMA.
Migrating Existing CAPF 1.0(1) Data
Caution Failing to perform the tasks that are described in this section may cause a loss of CAPF data. Use the following information in conjunction with the "Copying CAPF 1.0(1) Data from a 4.0 Subscriber Server to the 4.0 Publisher Database Server" section.
For information on using CAPF with Cisco Unified CallManager 5.0, refer to the Cisco Unified CallManager Security Guide.
Review the following details before you upgrade to Cisco Unified CallManager 5.0:
•Upgrades from Cisco Unified CallManager 4.0 where CAPF was installed on the Cisco Unified CallManager 4.0 publisher database server—If you performed certificate operations with Cisco Unified CallManager 4.0 and CAPF 1.0(1) ran on the publisher database server, the latest operation status migrates to the Cisco Unified CallManager 4.1 database.
•Upgrades from Cisco Unified CallManager where CAPF was installed on a Cisco Unified CallManager 4.0 subscriber server—If you performed certificate operations with Cisco Unified CallManager 4.0 and CAPF 1.0(1) ran on a subscriber server, you must copy the CAPF data to the 4.0 publisher database server before you upgrade to Cisco Unified CallManager 5.0.
Caution If you fail to copy the data prior to the Cisco Unified CallManager 5.0 upgrade, the CAPF data on the Cisco Unified CallManager 4.0 subscriber server does not migrate to the Cisco Unified CallManager 5.0 database, and a loss of data may occur. If a loss of data occurs, the locally significant certificates that you issued with CAPF utility 1.0(1) remain in the phones, but CAPF 5.0 must reissue the certificates, which are no longer valid.
•Upgrades from one release of Cisco Unified CallManager 4.1(x) to Cisco Unified CallManager 5.0—The upgrade automatically migrates the CAPF data.
Copying CAPF 1.0(1) Data from a 4.0 Subscriber Server to the 4.0 Publisher Database Server
Caution If you installed CAPF utility 1.0(1) on a Cisco Unified CallManager 4.0 subscriber server, you must copy the CAPF data to the 4.0 publisher database server before you upgrade to Cisco Unified CallManager 5.0. Failing to perform this task causes a loss of CAPF data; for example, you may lose the phone record files in C:\Program Files\Cisco\CAPF\CAPF.phone. If a loss of data occurs, the locally significant certificates that you issued with CAPF utility 1.0(1) remain in the phones, but CAPF 5.0 must reissue the certificates because the certificates are not valid.
Use the following procedure in conjunction with the "Migrating Existing CAPF 1.0(1) Data" section. To copy the files, perform the following procedure:
Step 1 Copy the files in Table 2 from the machine where CAPF 1.0 is installed to the publisher database server where Cisco Unified CallManager 4.0 is installed:
Step 2 Upgrade every server in the cluster to Cisco Unified CallManager 5.0.
Step 3 After you upgrade the cluster to Cisco Unified CallManager 5.0, perform the following tasks before you use the phones:
a. Delete the existing Cisco CTL client.
b. Install the latest Cisco CTL client by choosing Application->Plugins in Cisco Unified CallManager Administration.
c. Configure the client to create or update the CTL file.
Tip For information on installing and configuring the Cisco CTL client, refer to the Cisco Unified CallManager Security Guide.
The Cisco CTL client copies the CAPF certificate to all the servers in the cluster.
Step 4 Uninstall the CAPF utility that you used with Cisco Unified CallManager 4.0.
Step 5 See the "Generating a New CAPF Certificate" section.
Generating a New CAPF Certificate
The Certificate Authority Proxy Function includes its own certificate and private key that is used for authentication. If the CAPF certificate or private key does not exist, for example, after you delete the CAPF 1.0(1) utility, perform the following procedure:
Step 1 Save the current copy of the CAPF.cer file that exists in /usr/local/cm/.security/certs to a location that you will remember.
Step 2 Delete the CAPF.cer file that exists in /usr/local/cm/.security/certs.
Step 3 In Cisco Unified CallManager Serviceability, stop and start the Cisco Certificate Authority Proxy Function (CAPF) service.
Step 4 Update the CTL file; then, reboot all servers in the cluster.
Step 5 Verify that the phone downloaded the updated CTL file.
To run DMA on a Cisco Unified CallManager publisher server, perform the following steps.
Before you start DMA, make sure to review the information in the "Before You Begin" section.
Step 1 Choose Start > Programs > Cisco DMA > DMAAdmin.
Step 2 When prompted, log in as the Windows Administrator.
The Data Migration Assistant Home page displays.
Step 3 From the Data Migration Assistant menu bar, choose Backup > Storage Location.
The Backup Storage Location page displays.
Step 4 In the Backup Storage Location page
a. Choose the destination where DMA stores the tar file by clicking one of the following radio buttons:
–Network Directory—Stores the tar file in a network folder. Enter information in these fields:
Path Name—Network path to the appropriate folder
User Name—Username for network access
Password—Password for network access
–Local Directory—Stores the tar file in a folder on the server on which you are running DMA. In the Path Name field, enter the path to the folder or click Browse to choose a folder.
Note Do not specify a mapped network directory for the Local Directory. If you do, DMA may not be able to create the destination folder.
–Tape Device—Stores the tar file to a backup device. Choose an available tape device from the pulldown menu.
If a tar file already exists in the destination that you chose, DMA will delete that file when it creates the new one.
b. Click Update.
c. If you chose Local Directory as the backup storage location, click OK when you see this prompt:
Please ensure that you transfer the contents from the LOCAL path to an external device before upgrading. The files will not be readable from the local directory during the upgrade installation
Step 5 From the Data Migration Assistant menu bar, choose Backup > Backup Now.
The Migrate Data Source Server page displays.
Step 6 In the Migrate Data Source Server page, click Start Backup Now.
The backup begins.
A status window shows you the status of the backup as it proceeds. If you close the status window, you can display it again by clicking the View Latest Status link in the Migrate Data Source Server page.
The backup process can take a long time to complete. You can stop this process at any time by choosing Start > Programs > Cisco DMA > Cancel Backup and then clicking Cancel Backup Now in the Cancel Backup Process dialog box. The system could require several minutes to cancel the backup process.
Note If you close the DMA window while a backup process is running, the backup continues. However, when you restart DMA, the main window will display the Reset Status button. Clicking the Reset Status button cancels the backup process that is currently running.
When the backup completes, the status window displays the following lines:Archive built successfullyBackup information file DMABackupinfo.inf saved to D:\DMA
Step 7 If you saved the tar file in a local directory in Step 4, copy that file to a network server or to a tape device before you upgrade.
The following format shows how the tar file is named, where date and time indicate when the file was created:
You must perform this step because a tar file on the local disk will not be accessible during the upgrade process, and the file will be deleted when the upgrade process reformats the local server disks.
DMA Backup Information File
DMA automatically creates a backup information file when it backs up data. This file contains configuration and environment data regarding the DMA software, the server on which you ran DMA, and the software for which you backed up data.
The system saves the backup information file, which is named DMABackupInfo.inf, in the D:\DMA folder on the server on which you run DMA. The file also gets saved as part of the tar file.
Administering and Troubleshooting DMA
The following sections provide information that you can use to administer and troubleshoot DMA:
Determining DMA Software Version
To determine the version of DMA that is installed on a server, follow these steps:
Step 1 Take one of these actions to display the Data Migration Assistant home page, if it is not displayed already:
•If DMA is running, choose Backup > Home from DMA menu bar.
•If DMA is not running, choose Start > Programs > Cisco DMA > DMAAdmin and log in as the Windows Administrator when prompted.
