Hi. We currently have a five node Windows Server 2012 cluster (not R2).
We are wanting to create a new cluster in a new location and then migrate the existing VMs to this new cluster.
We have a new server that we built as 2012 and I was planning to evict one of the existing nodes from the old cluster, then move it over to the new location and make a new two node cluster.
The question is, should we create a new 2016 cluster or just do another 2012 cluster?
If we created a 2012 cluster, how hard would it be to convert this to a 2016 cluster down the road? Can you upgrade the nodes one at a time or do you need to upgrade them all at once?
Also, in either case, I was thinking of using Shared Nothing Live Migration (SNLM) to migrate the VMs across. Since this new cluster will be on an entirely different network, would it be easier to export the VMs and them import them at the new location?
Thanks,
Tom
