Move data from the old system to the new system as part of a software or platform upgrade. Tape drives are no longer supported in many recent CMS releases, and USB storage backups are not supported on VMware deployments. Therefore, use the Network File System (NFS) backup option when upgrading to a new CMS release.

A CMSADM backup is typically scheduled the night before the upgrade. Also, schedule a full maintenance backup to run overnight before the upgrade. If you are not performing incremental backups, run the full maintenance backup immediately before starting the upgrade. For detailed backup procedures, see the CMSADM backup procedures in Maintaining and Troubleshooting Avaya Call Management System.
