When you upgrade Communication Manager with Communication Manager Messaging, you must:
Add Communication Manager Messaging from the page.
Deploy Communication Manager Messaging OVA with a new IP address during Communication Manager migration.
Create a backup for messaging translations, names, and messages and create a separate backup of announcements if Communication Manager Messaging contains custom recorded announcements
For more information, see Upgrading to Avaya Aura® Communication Manager. The maximum limit for backup is about 50 GB. Communication Manager Messaging backup can be about 250 GB.
Perform the following tasks while creating a Communication Manager Messaging backup:
Create a Communication Manager Messaging backup on the Release 5.2.1 and Release 6.3.x systems.
For Release 5.2.1, install A9021rf+i.rpm and C1317rf+i.rpm on the Release 5.2.1 system on which Communication Manager Messaging is enabled.
RPMs are available on the support site in the Communication Manager 5.2.1 version downloads at https://support.avaya.com/downloads.
To verify the Communication Manager Messaging release, run the swversion command.
The system displays the following:
Messaging: +-N5.2.1-13.0---Ci+Ak+----
From the Communication Manager 5.2.1 system, create a backup of Communication Manager Messaging data and save on a different remote server that you can restore after migration.
Start the migration process from the System Manager web console.
The migration process shuts down the earlier Communication Manager and deploys Communication Manager and Communication Manager Messaging. For Communication Manager, System Manager automatically performs the migration process . The process includes installing the migration patch, creating the backup, deploying OVA, installing the feature pack or service pack, and restoring the backup on the Release 7.0 system.
When creating a backup of the system during the migration from Communication Manager Release 5.2.1 or 6.x with Communication Manager Messaging to Release 7.0.1, check for any additional languages. The languages must be restored on the Release 7.0.1 system before restoring the backup.
