Replication Types
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. Successfully
migrating a volume mapped to a server with minimal down-time consists of the following steps.
NOTE: This method is the only way to migrate volumes for SCv2000 Storage Centers and Storage Centers running
version 7.0 or earlier. For other
Storage Centers running version 7.1 or later, create a Live Migration to move the volume.
For more information on creating a Live Migration, see Create a Live Migration for a Single Volume.
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.
