How the hell do you successfully get your child to sleep through the night without a swaddle?

My son is almost 6 months and he will only sleep through the night in a swaddle. (I don’t need bitchy comments, I know he shouldn’t be in swaddles anymore. He sleeps in a bed where he can’t roll over) he doesn’t want to sleep without it. He just cries and is inconsolable. Help! How did you get your LO to get off of a swaddle?
