Data Protection for SQL Server migration

After you upgrade from an older version of Data Protection for SQL Server to a newer version, you can use VSS data restore operations to restore local VSS backups that were originally created with the older version of the software.

If you used a previous version of Data Protection for SQL Server in a Microsoft clustering environment and you upgrade to a newer version of Data Protection for SQL Server, 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 Data Protection for SQL Server are managed logically for the cluster. Except for the active backup, older backups eventually expire. When you no longer need to retain the active backup, you must delete the active backup by issuing the delete backup command. The existing backup copies can be restored.
