@hawkpro I believe it will be worse with continuous replication because your replica will be in a shut down state. When you decide to start it, you will have to shut down the original VM and start the replica. You will have a downtime during shut down and start up sequence. Downtime during VM migration is a necessity so there is nothing unexpected there. All types of migrations require a VM to be suspended for some time (usually seconds) during the switchover from one host or SR to the other host or SR. If you have extended downtimes of your VM migrations, then something is not quite right with your setup.
