Unable migrate VM from Hyper-V 2019 to Hyper-V 2022 (error 32784)

Question

Hi there, I have issue with Live migration between two hosts. One server is Windows Server 2019 Datacenter (Core). another one is Windows Server 2022 Datacenter (Core)
Both servers belong same domain and located in same VLAN (actually, they share one rack).
Kerberos delegation is configured for both servers. When I am trying move VM from server 2019 to 2022, I am getting error

It seems new hyper-v server does not accept live migration from old one. Is it bug? How can I avoid it?

Answer 1

Hello Sunnykey,

You have received the following error message

" Hyper-V did not find virtual machines to import from the location <folder location>.
The operation failed with error code '32784'. "

This usually happens when you try to import a VM that is exported from a Windows Server 2012 R2 Hyper-V host into a Windows Server 2012 Hyper-V host.

In order to overcome the above error you must execute the below steps,

1. Create a new NIC Team on a host computer or VM
2. Use live migration without Failover Clustering to move a virtual machine
3. Configure Multipath I/O for your StorSimple device

If Problem doesn't resolve, do follow the below link for detailed understanding,

I can confirm that this seems to be a bug in HyperV 2022 component.

We even cannot livemigrate via VMM 2019:

"The virtual machine "YYYY" cannot be migrated or cloned by VMM because the version "10.0.20348.320" of the virtualization software on the target host "xyz.XXX.de" is not compatible with the version of the virtualization software on the source host "10.0.14393.1358".

How can we avoid shutting down all the machines?
