Move Hyper V VM DC

Hi All, I want move a Hyper V VM Domain Controller(with all FSMO Roles) from one host to another host.

This is not a clustered environment, the VM DC is being backed up with Veeam, can I just restore the VM hdd to the new Host and fire it up or should I perform a Export/Import process?

I have read lots of articles that suggest this would be fine, but some say there may be replication problems, Unique ID issues etc.

I would appreciate any advice on this process

If you restore your backup AND your DC is ever online after the point of backup, you risk having issues.  The proper way to do this is shutdown the VM, Export it, then import it into the new host.  AND REMOVE IT FROM THE OLD HOST (If it ever comes back on, even accidentally, it could cause havoc on your network).  At a minimum disconnect it from the virtual network switch after you export it and while it's off!
Philip ElderTechnical Architect - HA/Compute/StorageCommented:
Using Veeam means that the restore process will be simple and quick on the new host once Veeam is set up there.

As Lee mentioned, make sure the source VM is no longer able to fire-up on the old host. Once the restore is confirmed good and clients can connect without issue delete the source VM.

If the vm is backed up, you already have one less problem to worry about.

You can do the following.

Turn off the VM
Disconnect the network adapter.
Exports the vm.
Then import it to your new host - Select the option to generate a new identifier.
Validate that the network adapter is connected when you import the vm to the new host.
Turn on the vm.

I remain attentive to the results.
