I have several VMs created on a WS2012 Hyper-V host that I want to migrate to a WS2019 host. Preferably Live Migration. Not in a cluser.
I tried it and got this:
"There was an error during move operation. Virtual machine migration operation failed at migration destination. Microsoft RDV Component (Instance ID [GUID]): Failed to restore with Error 'Catastrophic failure'."
Searched on that text and found an anecdotal response here--
--on the old TechNet boards that said MS only supports N-2 versions and 2012 R2 (in his case; mine is 2012) is too old. Suspect that could well be true. He also said Live Migration worked with VHDs but not VHDXs. I have VHDXs.
So he used offline migration, and I guess I will have to as well.
But is Live Migration version support documented anywhere? I could not find it here--
--or in the other documents in the Live Migration topics there.
