Okay... So if I were to do this, and system transfer the emunand from the o3ds to the o3dsxl, that would over-right the sysand with the emunand? This is a little confusing at the moment to me. Does it move the emunand to the o3dsxl along with the sysnand as well? Would that mean that the o3dsxl would be on 9.2 sysnand and then 9.7 emunand as well? And if I were to use rxtools emunand, that would mean I could only install 100% legit cia files correct? Also, I am deeply sorry that this is a little off topic for this thread. I appreciate every bit of help that is given.
I think you misunderstood what is a System Transfer.
Your O3DS XL will remain on 9.7 sysNAND (there is no way to downgrade it).
BUT your eShop account (or your NNID, if you have one) and your legal applications (by legal I mean those tied to your eShop account/NNID) with their saves will be transfered.
