I transfered using the 3DS system transfer tool from 3DS to XL. I also happened to upgrade my SD card to about 4GB if I remember correctly.
Unfortunately, everything transferred except the most important Save Data. (which was extremely annoying since I had to restart my digital 3 games at the time.)
I hate Nintendo with thier bad digital transfer stuff.....
