New server with Windows 2019 (Cluster Hyperv 2012 R2)

Hi,

I have a hyperv 2012 R2 cluster with two nodes.

We will replace these two nodes with new servers and we already want to implement with Windows 2019.

What is the best strategy for doing this migration?

Option 1

Create a new cluster and add the CSV volumes to the new cluster and import the VMs?

Option 2

Include the new Windows 2019 nodes in the existing cluster with the Windows 2012 nodes, do the live migration?

Thank you.
