IBM Spectrum Protect Snapshot migration

After you upgrade to a newer version of IBM Spectrum Protect Snapshot, use VSS restore for local VSS backups that were originally created with the older version of the software.

If you used a previous version of IBM Spectrum Protect Snapshot in a Microsoft clustering environment, and you upgrade to a newer version of IBM Spectrum Protect Snapshot, any existing backups that are completed on cluster disks do not count toward the maximum number of versions. New backups for clustered disks that are completed with the newer version of IBM Spectrum Protect Snapshot are managed logically for the cluster. Except for the active backup, older backups eventually expire. When you no longer must retain the active backup, the active backup must be deleted by using the delete backup command. You can restore the existing backups.
