In theory I suppose that you would only have to erase the RB3 content from the files you have on your computer if the other things are working properly though I don't know how you would do that...

I'm not completely sure that I understand your question completely but here's my best response.

You can't transfer the content from the Wii to a computer and then move it to the Wii U...

You can still do the random play online feature, there is just no Wii friend code list on the Wii U so you can't invite or be invited in that way.

Your profile transfers but unfortunately if you...

Everything transfers over to the Wii U, just the network won't read the old profile to upload to the leaderboards. Only profiles created on the Wii U will work normally. You can make fan progress if...

If you're unsure which system the drums are for, the center button that lights up will have the Xbox logo for Xbox, PS3 logo for PS3 or the Rock Band drum icon for the Wii.

Unless you have...

This is untrue. You can play online, even with people on Wii but have no friends list unfortunately. You can also connect to the leaderboards but only with profiles created on the Wii U.

Sounds to me like you bought a Wii drum set, not an Xbox one. Unfortunately, they are not cross compatable.

Edit: Also, if they are a Wii version and did not come with a dongle, they wouldn't work...

I'm sorry to say but if someone at Nintendo told you that, they either have no idea what they are talking about or they are lying to you. Nintendo is the only place that would have those records....

The Squier MINI will not work with RB3. It has no MIDI out as well as lacking the fret inputs that the RB3 Squier has. The only guitars that officially work with RB3 are the RB3 Squier, the Mustang...

If Doc can't find any, you can always use a 1/4"x20x3/4" bolt with a couple of finishing washers on it. It might not look exactly the same but if you went to a local hardware store and got some flat...

I re-downloaded all of my songs. I have 574 DLC songs, including several pro guitar upgrades though a few of those have been purchased since I did the transfer so I'm not sure the exact number I...

You can connect to leaderboards on the WiiU, just not with the profile that you created on your Wii. Create a new one and you're good to go. :D Sadly, you have to go from the ground up with your band...

Thanks mike3rdof5, that actually tells me more than Harmonix or Nintendo customer support told me in my several conversations with me. I can confirm that this does work! I'm sad to lose my old...

Actually, when I did the transfer and then put the SD card from my Wii into my WiiU without reformatting, most of the games were available but not the Rock Band songs for some reason. I can't say for...

Do the songs not show up as purchased in store or are the songs on your SD card just not working? If it's the latter, you need to reformat your SD card and redownload them all again from the Wii U....

I play on WiiU with my keyboard all the time and have not had this issue at all. As a matter of fact, I have not had one USB related issue on the WiiU when I had them relatively frequently on the Wii...

The exports have all worked since around Christmas. You just need to re-run the Wii to WiiU transfer tool. Leaderboards on the other hand, depend completely on Nintendo fixing the issue. Perhaps...

Unfortunately no, you can't. The Rock Band 1 kits do not have the necessary connections for the cymbals. The Midi pro adaptor is for intruments with midi out, which all RB drum sets do not have.

From talking to both Nintendo customer support and HMX customer support, I am near 100% sure that the fault of the leaderboards not working falls completely on Nintendo. As best I can understand...

I found a few listed by people on ebay. Can't verify the quality or anything, but that is the only place that I could find them listed.
