I actually just upgraded my 3DS to the 3DS XL.
- use a PC to copy everything from the 3DS 2GB SD Card to the 4GB SD Card that comes with the XL.
- Insert 4GB SD Card in 3DS.
- Launch transfer tool on both 3DS and 3DS XL, follow instructions.
- Take 4GB SD Card in 3DS out and put it in 3DS XL.
At this point, your 3DS XL will match what was on your 3DS. You will NOT have Mario Kart 7, it has been wiped.
Go to the eShop and find Mario Kart 7 - it will say "Redownload" rather than purchase, and you just dowload it to your 3DS XL.
