Bees will reorientate themselves if they're left, but you do lose a lot in a move. If you move them this trime of year, shove a load of grass in the entrance, so they have to spend a day or so chewing their way through it. They'll come out gradually, and most will reorient themselves to the new site. Some will still wander off. If you join the local Beekeepers' Association that gets you insurance, and there may well be someone willing to act as a mentor.
