After a successful replication group failover, you can perform a failback operation to reestablish replication operations for all replication pairs in the group. Only VMs that are eligible fail over. During a failback operation, all changes to the destination VMs are synced back to the source VMs.
Note
After failover, any configuration changes made to the destination VM, including adding or removing disks and changes to network adapters, will not support failback and the failback job fails. If only network changes are made, the failback job will complete but the source VM will not reflect the network changes.
Procedure
-
From the navigation pane, go to Auto recovery > Replication groups.
The Replication groups page appears.
-
Click the replication group.
The replication group page appears.
-
On the Overview tab, in the upper-right area of the page, click the Failover button, and then select Failback.
A message appears that asks you to verify that you want to perform the failback.
-
If you want to discard any changes that were made to the backup VM before the failback operation, select Discard the changes since failover.
If you select this option, the failback operation becomes undo failover operation.
-
Click Yes.
