Moving Machines to new hardware

This may be a dense question, but I feel like it might be one of those “you don’t know what you don’t know” situations.

We have bought some new servers to serve as hosts. But they are going to take a few weeks to get delivered. In the mean time, I would like to go ahead and create the new VMs on our current hosts and then just move them to the new hardware when it arrives. I know there are some things that vmotion needs to be compatible (processor, I think). They will be different between the old and the new, so I’m not sure vmotion will work.

However, I’m thinking that if vmotion doesn’t work, I could power off the VMs and then literally copy them over to the new storage and register them with the new hosts. Is there anything in this plan that I need to look out for or will that work as intended?

TIA

  1. You can set an EVC level to be compatible on all host in the cluster (now and in the future) to be able to vmotion when the new hosts are added to the cluster

    Moving powered off VM’s is also possible as u stated

  2. Are you just moving to different hosts or hosts and datastores? If it is just hosts, make sure evc compatibility is set properly.

  3. Yeah, you’re fine. If you’ve got the EVC modes setup on both clusters to match, you can vmotion live. If for some reason you can’t, you can always shut them down and move the VMs as a storage vmotion.
