I agree with what is being said.
If you get them altogether again and have nowhere to move them to that is 3mls away then have a read of this:

Additionally, if still not able to avoid the new location (have you contacted your local association or bee inspector?) Then some other ideas may help.
The trick is to ensure a complete reboot of a bees memory map takes place across as.many bees as possible.
So when they all in the colony seal it up and place a number of bushy branches across the front of the colony. Those that come out will be forced up and to re-orientate their mental maps. They are foragers looking for nectar and pollen.
It is usual to keep the bees in 3-4 days after a shorter move. You may choose this time of year to artificially feed 1:1 syrup or fondant and pollen patty.
The bees locked in until your ready and getting all their necessary food sources, it will be the start of your reprogramming.
So when you do open them you could place another food source close by the colony to focus the foragers attention, those that have started to re-orientate through the various branches etc.
You will need a hive in the old location to gather up the bees who still determine to return. This time of year you could be quite lucky in so far as many foragers will be winter bees who will be dying off soon to be replaced by fresh foragers who will accept the new conditions more easily.
Good luck,
