Where would I find the full Redwood Procurement roadmap, what needs to be turned on and when?

We are still using the classic version for all of our SCM screens, and we are aware that we need to move over to redwood for requisitions before 25C, is there any documentation of when other elements absolutely need to be transferred over to redwood? I have looked but there is so much information, I am looking for 1 key document that outlines it.
