Hacking From OG3DS Emunand to N3DS Emunand?

[Godson777]

I didn't want to post another thread asking about system transfers, but I can't find that thread I wanted to use to help me.

Basically I plan on sys-transfering my OG3DS's emunand to the N3DS (if the thread's title wasn't obvious.) So I can eshop with my NNID and stuff.

How do I do it? I used to know, but I kinda forgot and can't seem to find the thread with a tutorial on this.
