Overview of Data Migration Assistant


Note

Migration from Cisco Prime Collaboration Assurance 11.x to Cisco Prime Collaboration Assurance 12.1 Service Pack 3 is not supported.

This chapter provides an overview of Data Migration Assistant (DMA), explains how to install and use it, and provides related information.

DMA assists in migrating Cisco Prime Collaboration Assurance data from supported versions of 11.x to Cisco Prime Collaboration Assurance 12.1.

If you want to migrate from 11.x to 12.1 for both ENT/MSP modes, the following DMA paths are supported:

Mandatory Migration Path for 11.x to 12.1 customers, 

Install 12.1 FCS -> Apply 12.1 SP1 -> Perform DMA

Note

We recommend you to perform the following before migration.

Apply 12.1 SP1 on 12.1 Fresh installation. For more information on installing 12.1 Service Pack 1, see the "Readme for Cisco Prime Collaboration Assurance and Analytics 12.1 Service Pack 1".

Use the Backup RPM as mentioned in the "Readme for Cisco Prime Collaboration Assurance and Analytics 12.1 Service Pack 1".

12.1 Service Pack 1 Backup RPM can be downloaded from CCO at Software Download.

Path: Downloads Home / Cloud and Systems Management / Collaboration and Unified Communications Management / Prime Collaboration / Prime Collaboration Assurance 12.1 / Prime Collaboration Patches- 12.1 Service Pack1

The reason for migration is due to the change in the underline operating system of Cisco Prime Collaboration Assurance.

Data Migration Assistant is performed in the following method:

Note

  • We recommend you to perform DMA backup either during lean or maintenance period because Cisco Prime Collaboration Assurance Database (DB) restarts twice (once at the beginning and once at the end), as part of a few DMA configuration setup. This restart leads to inconsistent system after backup.

  • Currently, the time taken to perform a DMA backup of 50 GB data from 11.x server to 12.1 is around 4 to 5 hours. For a fully loaded setup it takes a minimum of 30 hours.

Preinstallation Guidelines

Review the following guidelines and perform the appropriate steps before installing DMA:

  1. If a PKCS7 or PKCS12 certificate is applied to 11.x and the Cisco Prime Collaboration Assurance is migrated to version 12.1, the certificate will not be restored. You need to regenerate the certificate for the Cisco Prime Collaboration Assurance 12.1.

    Note

    From Cisco Prime Collaboration Assurance 11.6 onwards, only PKCS12 certificate is supported.

  2. You cannot restore the purchased license of Cisco Prime Collaboration Assurance 11.x to 12.1. You must purchase the license with the same endpoint count for Cisco Prime Collaboration Assurance 12.1. Once the DMA migration is completed successfully, the Cisco Prime Collaboration Assurance 12.1 server will be in Evaluation mode.

  3. DMA backup is not supported in Cisco Prime Collaboration Assurance Release 11.x in "FIPS mode and Standard mode".

  4. DMA restore is not supported in Cisco Prime Collaboration Assurance Release 12.1 in "FIPS mode".

  5. If you have deployed in MSP mode, the Video endpoints with Public IP address(es) become Unreachable after DMA restore.

Following sFTP Servers are supported in the Cisco Prime Collaboration Assurance Data Migration Assistant.

Pre-requisites for Backup and Restore

Before you begin

Pre-requisites for Backup

  1. If you want to perform data migration from 11.0 or 11.1 versions to 12.1 version then first upgrade to the supported upgrade path of either 11.5 or 11.6 versions and then perform data migration to 12.1 version. For more information, see the table on "Supported Versions" in the chapter on "Overview of Data Migration Assistant".

  2. Enable Root Access on 11.x servers before performing Data Migration Assistant (DMA). For steps to enable root access, see Enable Root Access in 11.x Server.

  3. If you have created the Phone Status test in Cisco Prime Collaboration Assurance 11.6 server then it is mandatory to run the following commands. This way you can export the existing Phone Status test to a file that can be used to import tests after DMA migration.

    1. Login to the Cisco Prime Collaboration Assurance server as root.

    2. Create a new text file '11.6_PhoneStatusImportFile.txt' with read and write permissions at /opt/emms/cuom/ImportFiles.

    3. Run the following command: 
      /opt/postgres/9.2/bin/psql -p 5433 --username=cmuser  cpcm -c "copy (select 
extensionnumber, macaddress, ipaddress, saaipaddress from prphone) to '/opt/emms/cuom/
ImportFiles/11.6_PhoneStatusImportFile.txt' delimiter ':';"

      After running the above commands, you are required to delete all the Phone Status test created in the Cisco Prime Collaboration Assurance 11.6.

  4. Delete all the Batch and subsequent Synthetic tests from the Cisco Prime Collaboration Assurance 11.6.

  5. Backup is created with hostname in backup path (For example, if the backup path is /tempbackups then the backup will be available at: {ssh username}/tempbackups/{hostname}).

    Note

    The hostname of 11.x and 12.1 should be the same. If the values do not match, then DMA restore fails.

  6. The expected time taken for the DMA to complete the backup process varies depending on the profile and data of the backup server.

  7. Disable CDR/CMR configuration on CUCM Disabling CDR/CMR configuration on CUCM prevents CUCM sending bulk CDR/CMR(s). Perform the following steps:

    1. Go to CUCM Serviceability page of all managed CUCM publishers.

    2. Navigate to Tools > CDR Management.

    3. Select the PCA IP address/Hostname.

    4. On the Billing Application Server Parameters section, uncheck Resend on Failure check box and click Update.

      Note

      Make sure whether the check box is already unchecked.

  8. If Analytics is enabled, the Cisco Prime Collaboration Assurance and Analytics Database (DB) restarts during DMA backup.


Note

Backup must be taken from 11.x server with the RPM that is provided on CCO site.

Pre-requisites for Restore


Note

The system reboots after successful DMA restore.

  1. The expected time taken for the DMA to complete the restore process varies depending on the profile and data of the backup server.

  2. The Deleted state devices/endpoints will be purged and after the upgrade these (the devices/endpoints) will not be available.

  3. DMA restore on Cisco Prime Collaboration Assurance 12.1 should be performed through Serviceability after taking a DMA backup on 11.x server.

  4. The hostname of 11.x and 12.1 should be the same. If the values do not match, then DMA restore fails.

For information on preinstallation guidelines, see the section on Preinstallation Guidelines.

Preparation for Data Migration Assistant

  1. For Very Large Deployment, if Analytics is enabled, perform the following:

    1. Enable root for DBVM.

    2. Install the backup RPM in both DBVM and MainVM.

    3. Perform DMA only on the MainVM and when prompted provide password for DBVM on Cisco Prime Collaboration Assurance 12.1.

      If Analytics is disabled or if you do not require Analytics data to be migrated, then DMA has to be performed on the Application server.

  2. The hostname of 11.x and 12.1 should be the same and the IP address for both these servers should also be same. If the values do not match, then DMA restore fails.

Enable Root Access in 11.x Server

Perform the following steps to enable root access in 11.5 and 11.6 servers.

Procedure

Step 1

Login as admin from the Cisco Prime Collaboration Assurance VM Console. 

admin/admin# root_enable
Step 2

Configure the root patch password. 

admin/admin# root
Step 3

Enter the root password. 

ade# /opt/emms/emsam/bin/enableRoot.sh
Step 4

Configure the actual root password. 

ade# passwd

What to do next

Perform DMA (Data Migration Assistant) from Cisco Prime Collaboration Assurance Serviceability.

Perform Data Migration Assistant Backup

For Pre-requisites, see the section "Pre-requisites for Backup and Restore".

Procedure

Step 1

Copy RPM (as shown in the example below) to /opt.

For example, CSCOpca-dma-x.x-x.x86_64.rpm.

Note 

For more information, see the respective Read me of Engineering Special or Service Pack release for exact RPM name to be downloaded and used.

The RPM is available on the Cisco Connection Online (CCO) postings.

Step 2

Run below commands to install RPM. 

#cd /opt
#rpm -ivh CSCOpca-dma-x.x-x.x86_64.rpm
Note 
  • To verify whether the RPM is installed successfully, run the following command: 
    rpm -qa | grep -i CSCOpca-dma
    The command with an entry is displayed as follows: 
    rpm -qa | grep -i CSCOpca-dma
    Result: CSCOpca-dma-x.x-x
  • If the installation of RPM fails or exists abruptly, run the following command to remove the RPM: 
    rpm -e CSCOpca-dma--x.x-x

    Or 

    yum remove CSCOpca-dma-x.x-x
  • To verify whether the RPM is uninstalled successfully, run the following command: 
    rpm -qa | grep -i CSCOpca-dma
The result of the command should not display any entry (CSCOpca-dma-x.x-x).
Note 

If the error continues to occur, contact the Cisco Technical Assistance Center (TAC) for assistance.

Step 3

Go to directory /opt/emms/infra/dma/.

Step 4

Run script ./pcandma.sh.

Step 5

Enter the values when prompted:

  1. sFTP Server (IP Address): Enter sFTP server IP address to store the backup.

    Choose any of the sFTP server(s) where DMA backup can be stored and later fetched during DMA restore.

  2. sFTP Port: Enter sFTP server port number.

  3. User Name: Enter the username.

  4. Path: Enter sFTP server backup path.

  5. Password: Enter the sFTP password.

sFTP Port

22

UserName

Enter a name for the Username. For example, user1 or provide any desired name.

Path

Enter the path.

The DMA backup is taken in the path relative to the sFTP user home directory.

If path is /backup, the DMA backup location will be /user1/backup/{hostname}.

Step 6

Verify for backup in sFTP server at the configured backup location.

If the sFTP UserName is user1 and the configured backup path is /backup, then the backup resides at /user1/backup/{hostname}.

Here {hostname} is the directory created with the 11.x server's hostname.

Step 7

Backup file is generated in gpg format for Assurance and Analytics and uploads to sFTP server under the hostname folder under the configured backup location: /user1/backup/{hostname}.

For example, if /backup is the configured backup location, where the backup is available at /user1/backup/{hostname}, where user1 is the sFTP user home directory and backup is Assurance_Backup.tar.gz, Analytics_Backup.tar.gz.
