Migrating Volumes to Another Storage Center
Migrating a volume to another Storage Center moves the data on that volume to a volume on another Storage Center.
Using the following steps to migrate a volume to another Storage Center does not require a Remote Instant Replay (Replication) license or
a Live Volume license.
SCv2000 series storage systems running Storage Center 7.2 or earlier and all other storage systems running Storage Center 7.0 or earlier
can move a volume to another Storage Center using the following steps:
1. Create a snapshot from the volume you intend to migrate.
2. Create a view volume from the snapshot.
3. Replicate the view volume to the destination Storage Center.
4. Unmap servers from the volume you intend to migrate.
5. Replicate the volume to the destination Storage Center.
NOTE: An SCv2000 series storage system running Storage Center 7.3 or later and all other storage systems running
Storage Center 7.1 or later can move a volume to another Storage Center using the Live Migration feature. For more
information on creating a Live Migration, see Create a Live Migration for a Single Volume.
