I need to migrate a number of VM's to a new server and was wondering if it is possible to use the approach of replicating the VM's to the new server with the new server acting as the replica destination and then simply use these replicas as the main VM's on the new server and then switching off the old server once completed.
As far as I'm aware, the replica VM's are the same as the original ones and this should not be a problem. Is this correct?
If the above understanding is correct, could I then set up another (3rd) server to act as the permanent replication server for the new server?
To clarify, I have say 5 VM's running on HOST1. I would set up HOST2 to receive the replication of the 5 VM's. Once completed, I'd then start the replica VM's on HOST2 and have HOST2 as my main server and decommission HOST1.
The further question is then can I set up HOST3 to be the new permanent replication server for HOST2 and all will work well? So replica's of the replica.
Currently HOST1 runs Windows Server 2012R2 and HOST2 will run Server 2016, a quick read indicates that you can replicate between these two OS's. Happy to be corrected on that though.
I can't think of a reason why this would not work unless Hyper-V knows they are replica's and wouldn't allow this operation.
That being the case (not possible to do this), I could export them, but this would take longer and I prefer the replica router as they'll be more up to date when I come to make the changes and I want to minimise downtime.
All comments/feedback on this approach?
