that's what I did, and I had no problems. I don't use the emunand though (not sure if it will work on a wii u), but I have nearly the entire wiiware database saved to my computer. I got it from iso before that site went down. anyway, some saves may not transfer due to copy protection, but they will with save manager gx.

I think I got my mii over to my wii u. it's named "the beast" and it kinda looks like me.
