The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter provides information on DMA (Data Migration Assistant) and the procedure to set it up.
Data Migration Assistant (DMA) assists you with the first step in migrating Cisco Prime Collaboration Assurance Serviceability data from earlier versions (11.5 or 11.6) by exporting this data in a format that Cisco Prime Collaboration Assurance Serviceability can read.
Whenever you migrate from 11.1 to another version it will be on the same Cisco Prime Collaboration Assurance server. For example, you have 11.5 and want to upgrade to 11.6. This means, in the Cisco Prime Collaboration Assurance equipment with the 11.5 version, the command to migrate to the latest versions is executed. So, migration happens in the same Cisco Prime Collaboration Assurance.
In version 12.1, the operating system is changed to CentOS. Hence, during migration, you must execute the backup utility in 11.x. Consequently, you must download the backup utility from CCO, execute it on the Cisco Prime Assurance server with 11.x. This action will generate a target (tar) file and upload it onto a sFTP remote server.
DMA is meant for moving data from 11.x to 12.1.
In 12.1 - To perform DMA, click DMA. Provide sFTP details and start the migration process. It downloads backup file from sFTP server and migrates the database. It is a one-time activity. On successful DMA migration, the data from 11.x server is available in 12.1 server. The login password remain unchanged (will be the 12.1 password).
Choose DMA.
Note | The system reboots after successful DMA restore. |
Step 1 | Enter the
following values on the
DMA page.

Step 2 | Click
Test
Connection to test the sFTP connection.

Step 3 | Click Start DMA to perform DMA restore. | ||||||||||
Step 4 | During this
process, a progress bar appears indicating the progress of data migration. You
can also click on

Detail link to view the DMA status detail log.
A notification also appears once DMA is completed. | ||||||||||
Step 5 | If DMA is
successful, you are redirected to the dashboard.
Login to Cisco Prime Collaboration Serviceability and Cisco Prime Collaboration Assurance using the 11.x password. Logging on to Cisco Prime Collaboration Assurance Serviceability provides access to all the menus. Consider the following methods to validate DMA. For information, see Validate Data Migration Assistant. | ||||||||||
Step 6 | If DMA fails, you can view the failure log. The login to Cisco Prime Collaboration Assurance Serviceability User Interface mandates DMA to perform again. |
Consider the following steps to validate DMA restore.
