I'll admit I've never personally done this, but I would think that probably the worst thing that's going to happen as a result of moving the carboy is that you stir up a little bit of sediment. Depending on how long it's been fermenting and whether there are still some fermentable sugars, the motion might also kick-start some of the yeast into another minor round of fermentation. Just be careful moving it and let it sit for another week or so before bottling, and you should be fine. Good luck with the move, and RDWHAHB.
