We took the opposite approach when our new AP arrived but we had the room.....old AP did not travel, but moved into the guest room for the month. New AP got the AP room (which has its own bath) so she could get settled, but old AP did a lot of work to get new AP setttled in. It worked well for us, but I understand that if you don't have the room it could be a challenge. I would do as the pp said and get the LCC involved. Maybe you could offer that she could stay on the couch for a week or so?
