Unfortunately, you're unable to transfer save files between Wii U consoles at this time. This was one of the main reasons cheat codes existed back in the day. It might be worth emailing/calling the game company to see if there's some kind of trick/code to skip ahead. I'm assuming during this day and age, you might be out of luck.
Now you have an excuse to play your kid's video games though
