So a year ago I bought a Luigi Manson 3DS from Best Buy along with a 1yr AD warranty. The wifi switch has been turning off on him every once in a while, so I talked to a Geeksquad agent that said I would have to take it to a Best Buy store, and it's possible that they may just replace the 3DS. So I'm planning to transfer the stuff from my 2DS to my old 3DS and transfer his 3DS stuff to my old 3DS as well.
So I have 3 questions, 1st, has transfers been made easier since a year ago, 2nd, can I do 2 transfers within a couple days, and 3rd, can I reconnect my 2DS to the Nintendo ID that it had before the format?
(Yes, I know that you guys aren't Nintendo employees, but I figured someone might know, and if not, I may call Nintendo.)
