Can you move completely to formula?

Hi there! Have been EP’ing for 6 weeks & am looking to stop & move to formula exclusively. Is it possible to do this right away, or do I need to gradually introduce formula bottles along with my breast milk bottles throughout the day?

He already seeks to tolerate the formula we have been giving him (Bobbie, regular), potentially even better than my breast milk? So wondering if we have to ease into it or if we are okay to drop the BM now completely.

Thanks!
