I wouldn't feed him until 1 week after moving into your new place. You don't want to feed him and then have him regurge because of the stress of being moved.
Edit: Normal handling is usually fine after 48 hours but moving into a new house with all the vibrations, being jostled around, etc is a horse of a different color. I would prefer to be safer than sorry. Regurgitations are tolling on a snakes digestive system.
