I don't have VCD Elastic turn on at the moment. I would imagine it's not just something that I can enable and add the new cluster in and not making major changes to the Provider VCD and causing an outage.
I have VXLAN setup and that takes care of that part. Having 2 clusters will reduce the inconsistency of where and when the VM's will land causing new hardware detection reboots.
I don't think our automation process will be able to detect which cluster to VM's are landing in and be able to deal with the reboots.
This solution worth considering... Thanks for the suggestion.
