I started this game on my wii u, through wii mode, on the virtual console.

My wii U has a problem of turning off automatically, mid-game. This has been an ongoing issue, but I thought it had finally resolved itself, but today, it did it again

As a result, I have decided to just buy a new wii u from scratch.

However, I do not want to lose my save data for FF1.

Can someone explain, step by step, how I can transfer my FF1 save data from my old wii u to the new one when it arrives?

I've searched online, but I know this is a complicated case, because I am talking about VC data from a wii mode on a wii u.... rather than just a wii itself.
