it's called the strangler pattern, where the new version is layered on top of the old and gradually replaces it.
it usually doesn't work.
Man I’ve never seen it not work. It’s pretty much the only pattern I use because it’s so successful. Meanwhile the other teams in my company have numerous failed migrations because they try to rewrite the entire thing at once instead of using the strangler fig pattern.
only time i've ever tried it was in a duolith consisting of over half a million lines of python, all of them critical.
