Upgrading / Downsizing compute in local data center (2 Hyper-V Cluster & 1 Hyper-V Host -> 1 Hyper-V Cluster)

Hi everyone,

as we are moving more and more services to the cloud we want to downsize our data center.
We want to make 5 hosts to 2 hosts with less or no downtime.

We cannot use live migration as our storage is filled ~60%. The storage is being reused afterwards. So no (not yet) Azure Stack HCI with Storage Spaces Direct.
I have read about the rolling update of clusters. But this only describes one cluster being upgraded and not a merge.

Anyone can tell me a high level migration approach?

Best regards
Stephan

Hello

Thank you for your question and reaching out.
I can understand you are having some queries related to downsize of Nodes.

In my opinion you can Evict Hyper-V nodes one by one and Re-use them on your new Cluster.

You can also use Storage services migration to Copy Live VMs DATA or .vhdx while they are running.

But i get 2 new Proliants that will host all the VMs in the end. I do not want to reuse anything but the SAN.

The quick migration is not an option for at least one VHDx (Size 6TB)
