It seems to be a question that often pops up on the VMTN forum, how can I move my ESX hosts to my freshly installed vCenter server? The answer is actually pretty simple:
- Just to be on the save side, set DRS to manual and disable HA on the “old” vCenter server / cluster
- Right click the ESX host and select “Disconnect”
- Go to the new vCenter server and add the host
It’s as simple as that. You don’t even need to shutdown your VMs.
Keep in mind though that you will lose your folder structure as well. (Thanks Joop)
