Hi everyone. I'm looking to do a system transfer from an Old 3DS XL to an N3DSXL. No illegitimate games on the Old 3DS, just some eshop demos and the homebrew apps when you mod it. N3DS was wiped and just recently modded. I want to still use my old 3DS as a 2nd one, mods intact. N3DS will be my new main one with all my old 3DS' data, as it's presumably faster. Both are using micro SD cards btw.
Anyway, after I do a system transfer, do I just swap micro SD cards? Is it that easy, nothing's tied to the original system? Also they were modded on different firmwares (N3DS on 11.04.0-37E, Old on 11.17) using different methods and then updated. Does that matter? Will the files be the same regardless?
Also do I have to worry about nand before/after transfer or will it be fine? I'm quite new to doing that, so hope not haha
Thanks, I don't want to mess anything up. If anyone has done this (a system transfer and kept using the old system) before, please let me know. I'm not cloning it btw, just transferring all my data from old to new.
