Transitioning out of Merlin Sleep Suit

My 6 month old is becoming more mobile. He is starting to roll from front to back and back to front - he rolls several times daily. He has not yet rolled in his crib but I know it is coming. We are now transitioning him out of the magic Merlin sleep suit. We are on night one and he is in an ergopouch sleep bag. So far, he has woken up every hour😭😭😭.

My question is, has anyone had success transitioning out of the Merlin sleep suit? If so, what did you use after the suit (sleep bag, etc) and how long did it take for baby to sleep well again? Tia!!!
