I've searched and couldn't find a definitive answer to this. I have an o3DS with 9.2 sysNAND and 10.6 emuNAND. I want to purchase a n3DS. So I want to transfer my NNID and then return the o3DS back to stock 9.2. What is the safest way to go about this, I don't care about transferring games, I can put those back manually.
