All of my games are on a 2GB SD Card and I really want to switch to an 8GB and I found [this] but it doesn't specify if I can copy over my save data with the software data. Has anyone ever had to do this (successfully)? Please help~
You can do it with software. When I went from my 4GB to 32GB, I had some small games on there. I copied the data and it all carried over correctly. No save data was lost, and I didn't have to re-download anything.
Just make sure to format the new SD card as per their instructions, and you'll be fine.
