One thing that survived was my Wii Fit data that goes back to 2009. But now, b/c I'm using a different Wii U, when I turn on the game I'm getting the 30 day countdown that I need to register a Fit Meter to keep it. However, the option to register my Fit Meter doesn't show up in the game. So I called Nintendo. They had me try to reset the Fit Meter, and delete the Fit Meter (not a big deal)....
