Topic: I need help moving games from one 3DS to another.

I have had a 3DS xl and a normal 3ds for a while now with both different NNIDs and I want to move all the data to my 3DS xl. Correct me if I'm wrong, but if I unlink my NNID from both 3DS's then after the transfer link my 3DS xl again I can redownload all my games that were previously on my 3DS xl. I want to be sure before I do anything because nothing I looked up helped me with my problem.

Call Nintendo.

That's one thing you could have done rather than create an account just to ask this question to laymen.

Not entirely sure what you're trying to do, but you can't combine nnids nor transfer games from one nnid account to other.
