Migrating Current Data Back to the Primary VM

If a DR VM has been running long enough to accumulate new data that you want to preserve, you can migrate this data back to the primary VM with no data loss.

When you migrate data back to a primary VM:

• The direction of DR protection is reversed (that is, snapshots are sent from the DR VM to the primary VM).

• DR protection is resumed for the reverse direction.
• The DR VM is shut down, and a final snapshot of it is taken. The user clicks Finish Migration to initiate the final steps.
• The final snapshot is replicated to the site where the primary VM resides.
• The primary VM is started.
• The direction of DR protection is returned to normal operation (snapshots sent from primary VM to DR VM).

To migrate current data back to the primary VM

1. In the Stratus One View Console masthead, click VIRTUAL MACHINES.

2. On the VIRTUAL MACHINES page, click the DR VM that corresponds to the primary VM.
3. In the action bar, click Begin Migration.

4. The system begins to take snapshots on the DR VM and copies them to the primary VM. When the system finishes migrating the data, the Finish Migration button appears in the action bar. Click Finish Migration to complete this operation.

   The DR VM is shut down. One more snapshot is taken and copied to the primary VM. The primary VM is started.

   Note: This operation automatically enables DR protection on the primary VM; you do not need to enable it manually.
