Back when the latest update was 38.3 I was love this game and tried it multiple time. Due to irl things now I'm back is there any thing I have to worry about when transferring data?
Putting new version files over the old ones should work fine. There might be some slight issues, but nothing major. I'd still recommend starting new game as soon as possible. I take extra care to make sure all unlocks from previous playthroughs stay compatible with new versions.
