We should be able to restore Hyper-V 2019 VMs on Hyper-V 2016 if the config version is 8.0

Post by birdwaffle » Jun 19, 2019 10:08 am

Hi, I'm new to the forums. I hope I posted this in the right place.

I have a Hyper-V 2019 with VMs in configuration version 8.0 (Hyper-V 2016's version). This allows me to migrate the VMs to a Hyper-V 2016 if need be.

Now, when I try to restore these VMs on a Hyper-V 2016, it won't work.

Is there a reason, we cannot do this? I think we should be able to do this if the configuration version is compatible between backup and the target for restore.

Hello and welcome to the community birdwaffle,
Now, when I try to restore these VMs on a Hyper-V 2016, it won't work.
Can you please share the text or a screenshot of the error you got during restore? Thank you in advance!

Yes, I have a screenshot and an output of the VM configuration version:

The config version is 8.0

edit: Source Server is Windows Server 2019 (10.0.17763) and the target server is Hyper-V (standalone) 2016 (10.0.14393)

Hello birdwaffle,

Unfortunately it's a known limitation described in the Help Center:
Before You Begin wrote:The version of the target host on which the VM is restored must be the same or later than the version of the source host where the original VM was registered.
For example, you can restore a VM from the host that runs Microsoft Windows Server 2016 to the target host that runs the following versions of Microsoft Windows:

Microsoft Windows Server 2016 (including version 1809)
Microsoft Windows Server 2019
The Hyper-V role must be enabled on both source and target hosts.

I see. Thank you @Dima P !

I just want to add, it shouldn't be a limitation because in my mind if I have a backup of, say, a VM config version 8, it shouldn't matter where the backup came from. Therefore I should be able to restore it on any Hyper-V version that can handle version 8 VMs. Am I wrong?

I agree it should be possible since you can live migrate a VM on config version 8.0 to a Hyper-V host running 2016. Veeam should look at the config version of the VM, not the version of the host OS.
