The couple of times I've had to move mine, this is what I've done (what Bob and the others have said). I'd like to emphasize one of Bob's points: do not trust the locking mechanisam. That is, perhaps, the only flimsy part of the enlarger. Find some other way to lock the head in place. I've generally raised the head fully and wrapped the raise/lower knob with plastic packing tape to keep it from moving. If you pad it and set it on its side it should travel fine.
