I got a N3DS XL recently and wanted to move all my data from my o3DS to my new one. However I didn't want everything from my o3DS to be reformatted. So what I did was back up the NAND on my o3DS before doing the data transfer then restored the NAND afterwards, creating 2 identical 3DS's. The problem is, Both 3DS's now share the same FC, NNID (which I removed, hopefully I did it fast enough before Nintendo noticed.), streetpass, etc. Will this cause any problems? Can I change my FC? Some reassurance/help would be great!
