Live migration supported versions

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--

https://social.technet.microsoft.com/Forums/en-US/11bed354-e5cd-4cd8-a100-02656bf460d8/impossible-to-livemigrate-vms-with-vhdx

--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--

https://docs.microsoft.com/en-us/windows-server/virtualization/hyper-v/manage/live-migration-overview

--or in the other documents in the Live Migration topics there.

TIA

You can see the supported versions matrix here.

Thanks for your reply, but that matrix is telling me which VM versions are supported on which host versions. It is not telling me across which versions I can use Live Migration.

Unless they're SUPPOSED to be the same versions, and my experience and that of the TechNet OP indicate a problem.

Successfully offline-migrated a VM, which also matches experience of TechNet guy.

He ended up using an intermediate WS2016 host. I won't have that luxury.

As far as I know that's too big of leap 2012 -> 2019 live migration.

Prolly so...I'd go so far as to say, empirically so.

But wouldn't it be awesome for us admins with older-but-still-supported servers if there was an official reference that told us what we can and can't Live Migrate? Unless I'm still missing it, there isn't. I've submitted the suggestion; we'll see what happens.
