There are a few who have the ability to do
soul swapping. But it's not something most could ever attempt to do. I would advise against even trying. The 'pro's still have problems to face when they find a new body. It's a rather long process, and you tend to lose memories. It's not exactly pleasant.
You won't get the answer here. It's a very long process, you loose alot of memories. It's not like saying few words and boom done. Those who have done it, regret of doing it. Some use it for immortality, you can't really say those are 'people' anymore..
