I have decided to privately update Crash Landing (Modpack) from 1.6.4 to 1.12.2 so that I can add more mods etc of my choosing but I wish to carry the map across with it. They use a premade map to which is in a template folder. Upon copying the template folder of the origional it said it was not compatible and must be launched in 1.8 or 1.7.10 first. I tried this then carried it across to which the same issue occured. Is there anyway I can get the map across to 1.12.2?
