I'm assuming you are talking about moving between two Disney resorts. So, yes it is very doable. On the day you check out of the first resort, you tell bell services (or whoever it is at your particular resort) that you need your bags transfered to such and such a resort. Then you can go on over to the new resort, check-in and possibly get into your room. If it isn't ready yet, go off to eat or go to a park. Check back later in the day and go find your room. Your luggage should make it to the new resort by late afternoon. It is all very easy within Disney. But remember, take along anything you might need before you get your main luggage later that day. You can rent a locker in the parks if need be. We have done this several times and had no problems.
