Hi John,
I have faced this same predicament myself, because i didn't have another yard or location. In short, you can either just move the hive and let the field force find their hive via pheromone. Those that dont will drift into other hives that may welcome them with all the goodies they have with them. Otherwise, you can wait till its almost dark and you feel you got most of them in and lock the entrance and just move them. The next morning, and it doesn't have to be first thing either, you can place some bush or brush or some object directly in front of the entrance so to force them to re-orient.
To give yourself added peace of mind, just place a nuc with a few frames at the previous location, if you find some that went back to the original location you can dump them in their permanent location later. But you may find yourself doing this quite a bit. I would just let them find their home on their own. They can and will find it, but it will look alarming to you. But be brave, they know how to find home. Trust in your bees!
Good luck.
