Live Migration between WS2012 & WS2022 hosts?

Question

I have found this article--

hyper-v-feature-compatibility-by-generation-and-guest

--which says Live Migration can be done if the guest OS is supported. I'm wondering if I can Live Migrate WS2012 VMs from a WS2012 host to a WS2022 host, and I've not found anything about Live Migration compatibility between hosts. I do know I had problems with a Live Migration from another WS2012 host to a WS2019 host and ended up copying the VHDXs to the new host with the VM offline. But in that scenario, downtime wasn't a big problem. Here I have a very large VHDX to copy, and downtime will be harder to come by.

Is Live Migration from WS2012 hosts to WS2022 hosts possible & supported?

Answer 1

Hi,

I'm afraid you cannot move a VM from WS2012 to WS2022 because they support different VM configuration versions. WS2012 supports version 5.0, while WS2022 supports version 8.0 to 10.0.

Thanks for your reply!

I guess I'll have to call an outage to copy the VHDXs and create new VMs. Wish I could get my clients to stay no older than v.current - 2.
