Ok, I have an old 3DS XL I just put CFW on without issue. This was an old system which I transfered my account from to a New 3DS XL when they came out and haven't really used since. I know I should now be able to use that old 3DS XL to install CFW on my main New XL. My new XL has my Nintendo account on it, how do I go about doing the transfer? Can I just use the account free old XL and transfer as it is to the new XL and then restore my NNID back onto the new XL once done? Also do I need to make a throw away NNID on the old XL to buy one of the needed eShop games? What state will it leave the old XL in, can I just start using again with no account or a new account, or do I need to do more? Additionally what are the risks to my NNID, does a 3DS ban kill the whole account or just a device, I have Switch purchases I don't really want to risk? Hope that makes sense, basically what's the best way to manage the NNID if do it with a New XL (using NNID) and a CFW enabled Old XL (no NNID)?
