Hey
we have a few ESXi hosts running the original 5.0.0 version, and a few running the latest 5.1 U1 or whatever, and the latest vCenter for this too.
the vCenter server is on one of the hosts running 5.0.0 and these won't allow HA to be enabled properly. The issue is a known bug, and you have to go into maintenance mode and do funky stuff on the cli to get it working. However, I simply want to move all my vms off the old 5.0.0. hosts and onto the new ones, as the old ones will be decommissioned. I can do all the vms by simply shutting them down and migrating when off, but I won't be able to do this in vCenter with the vCenter vm off!
can I power it down, connect to the ESXi host directly, remove it from it's inventory (does this option even exist on the ESXi host direct?), and register it on the new 5.1.0 U1 host and fire it up?
will vCenter complain or fail when it comes back up?
they all share the same datastores, so I don't need to move the backend.
thoughts?
thanks
Roger
