Unfortunately the update script will only work with unaltered versions. It's going to start out being fairly basic, transfer your files over, run the updater and it will check if there are any altertables to run and in what order. If there are hacks to the code then you'll still need to manually make these changes. It would be nice to be able to have it work with hacked versions but that wouldn't really be possible since sometimes code gets totally moved around, deleted, etc.
