Move them after dark. Smoke any that are hanging out outside, into the hive. Seal up the entrance, and make the move as gently as possible. How far are you moving them? I cut a 1x2 piece of poplar the exact size of the hive entrance, and put a couple screws in one side like handles. I can close up the hive like closing a drawer. Two little pieces of tape on each side for added security, and off I go. (think entrance reducer with no holes)
