I apologize if this is covered somewhere here already... just point me there if so.
I have a four host vSphere environment (two hosts in a cluster at main site, one host in a cluster at two remote sites). The hosts at the remote sites are ancient and I need to replace the hardware. Though the main cluster is running vSphere 5.5 (and this is also where the Veeam server lives), the remote sites are still on 4.1. I was hoping that I could do the following:
1. Install new vSpher 5.5 host at remote site (can I even put a 5.5 host in the same cluster as a 4.1 host?)
2. Veeam QuickMigrate the three small VMs from the old host to new.
3. Decommission old 4.1 host.
I don't see a need for EVC and all that to do vMotion between old and new since I have so few VMs... just wondering if this is a viable plan or if there's a better way.
