General questions from a first time user...

Well, for a start, with a different board the pinout is going to be different, and the available peripherals may be different.

First of all, you need to check the specs of both boards, and see what peripherals the project is using. If you have a like for like match, then you just need to change the pinout and away you go. But if they are different, then you may have to do some major project overhaul as they may have different specs, so the controllers will need re-writing.

It might just be easier to start your own project from scratch, especially as a beginner.
