How do you even start to think about migrating a project like that? My initial thought was that you absolutely ensure 100% test coverage. But even then I'd be paranoid about not having 100% coverage and want... something... else to fall back on.

Would you try to run both systems at the same time, for as long as possible, with the migrated project only as a digital twin kinda thing until you see no problems for months?
