Hi,
We have a customer that today has esxi4 and vcenter 4.
They have configured a new vmware system beside this one, with esxi5.5 and vcenter 5.5
They are going to make the old SAN (FC) available in the new vcenter. But how should we migrate the vms.
Could we just add one of the old esxi4 to the new vcenter 5.5 without interrupt any vms, and migrate them over to 5.5?
Or should we clone these vms? (some are Domain controllers)
Feel free to come with suggestions
