Complete a Live Migration
Complete a Live Migration to stop server I/O requests to the old source Storage Center and send all I/O requests only to the
destination
Storage Center. The old destination Storage Center is now the new source Storage Center. You can complete a single
Live Migration or multiple Live Migrations at one time.
Prerequisites
• Swap roles must be complete for the Live Migration.
• The Live Migration must be in the Ready to be Completed state.
Steps
1. Click the Replications & Live Volumes view.
2. On the Live Migrations tab, select the Live Migrations you want to complete.
3. Click Complete.
The Complete Live Migration dialog box opens.
4. Verify the Live Migrations to complete, and then click Finish.
The Live Migration completes. The server stops sending I/O requests to the volume on the old source Storage Center and the
Live Migration is removed from the Live Migrations tab. The old source volume receives a new device ID and all mappings are
removed.
Enable or Disable Deduplication for a Live Migration
Deduplication reduces the amount of data transferred and enhances the storage eciency of the remote Storage Center.
Deduplication copies only the changed portions of the
snapshot history on the source volume, rather than all data captured in each
snapshot.
