have an old 5.5 esxi host (same vcenter) Out of need due to resources on another host I had to build an exchange server on it. It didnt' have much in the way of diskspace and because of the swap file taking up 50gb I only have 400mb left on the local storage, my mailbox databases reside on an iscsi volume. OS on local. I can't even backup because of the low space on local. I want to move that OS drive to the Iscsi Volume. Is it as simple as turning VM off, migrate and powering on?
