HOW TO move ESX hosts between clusters without maintenance mode
I’ve done this a number of times and never had a problem, but this may not be a good idea.
The steps are to:
1. Right click and disconnect the ESX host from vCenter.
2. Right click and remove the host you just disconnected from vCenter (may hang VC temporarily in the minute rangeor operation may time out) re-log back into VC, once you are able to it host should be gone from the cluster.
3. Re-add to VC under new cluster
