This is my (quite possibly flawed) understanding at present:
- Undo Failover - Discard all changes that were made to the replica while it was running and return operation to the original VM.
- Permanent Failover - Abandon the original VM and switch to a VM replica on the cloud host and use this replica as the original VM.
- Failback - Return operation to the original VM or a replacement VM. Finalize (commit) to fix the original replication job if necessary.
Is there no option to go from a replica VM back to the original VM and bring changes back with the switch?
I think I've managed to sufficiently confuse myself (not hard), so I appreciate any clarity that can be offered.
