Hardware Safe to system transfer?

[Koshigaya]

I'm going to be transferring an O3DS to a N3DSXL, neither are modded but the N3DSXL is on 9.6.0. Doing a system transfer doesn't transfer firmware correct, only game data?

You won't be able to System Transfer anyways due to needing to be on the same latest firmware for a System Transfer. (unless you use Httpwn ; don't know too much about Httpwn)

You said both aren't modded so I'm presuming there's not even Homebrew on it.

Both systems need to have the same NATIVE_FIRM version for the transfer to work, I believe.
My suggestion is to hack the o3DS (assuming it is on 10.7 or below) with A9LH, update both consoles, and use the o3DS to hack the n3DS.
