If you are moving it yourself, and presumably being careful, there is no problem with leaving the tubes in the amp. Removal is a precaution when the amps will be in the hands of uncaring strangers; that kind of handling can be brutal--dropped boxes, boxes that are turned upside down, etc. I bet that makes the move just a little bit less of a hassle.
Moving tube equipment
I will be relocating some tube based amps soon. Since I'm doing the packing and driving (about an hour and 15 minutes) any thoughts on just leaving the tubes intact and packing carefully so the units cannot shift. After unpacking just check to make the tubes are still properly seated. The amps are not auto biased so having the right tube in the correct socket matters. Yes I'm just being lazy and would rather not pull the tubes and mark etc....
