USB drive should now a) be recognized by target Wii U and b) have useable save dataĪnd so we encounter our problem.After drive is formatted, copy save data from computer to USB drive.If target Wii U reads data - success! If not, format USB drive for target Wii U.After NNID transfer is complete, insert USB drive into target Wii U.

Copy all data from USB drive to another drive (e.g., computer).While logged in as NNID to be moved, copy save data from source Wii U to USB drive.The second person we spoke with suggested that it may still be possible to transfer save data. We have already initiated the process of transferring their NNID's to their console we're just waiting to get the go-ahead from Nintendo to try to use them on their Wii U. Especially considering that I also have all my original Wii data on my Wii U, this is simply not a solution. However, Nintendo's support site as well as the first person we spoke with says that for save data to be transferred, a complete system transfer must be done this moves EVERYTHING, and formats the source system. We called Nintendo, and they said it is possible to transfer their NNID's from my Wii U (the source system) to theirs (target system), which will transfer the ID as well as any purchased content (it will be queued to re-download on their console). They just got a new Wii U, and we want to transfer their NNID's (Nintendo Network ID's), purchased content, and save data from my Wii U to their Wii U while leaving all of my data alone. For several months I had been keeping my Wii U at my friends' house.
