I have several doubts.
I have two consoles, one Old 3DS (with A9LH) and New 3DS (with newly installed A9LH). Both are in the latest version, but the first one is the one that has my NNID actually linked and the N3DS is virgin (recently bought).
My questions are: What happens if I do a system transfer between the two consoles? Do I lose games and / or data of the O3DS (including SD games)? By transferring the NNID, the console (old one) becomes unusable for online? Can you play online without linking a NNID?
I imagine that having both in latest FW and the A9LH + Luma fully configured, the transfer process could be said to be "automatic", ie, without worrying about anything, right?
