agreed, but a amalgam of both usually works.
whenever I am P2V'ing a DB or Exchange server (read any server with heavy datachange) I get a migration window where I can stop all necessary services.
This leads to a clean migration. Never do a DB hot Image may be NSFW.
Clik here to view.
This is the main reason that AD controllers cause so much issues, their services can not be shut down so are never in a quiesced state
