Topic: Swapping SD cards back & fourth on 3DS?

If your current 3DS's SD memory card runs out of space can you use more then one SD memory card and swap them back and fourth? I've read that Nintendo tech support does not recommend using more then one SD card with a single 3DS due to possible data corruption however I've read from a few 3DS owners who use more then one card on their 3DS without any problems, Anyone here use more then one SD card on your 3DS?

But if I were you, I'd just buy a new SD card. They're dirt cheap anyway.

I've done it, never had a problem, however like the guy said above me its just better and easier to get a new one.

I'm wondering how would a system transfer work if your using multiple SD cards, since only one SD card is in the source 3DS during a transfer, once the transfer is complete can you just put the other SD cards in the target 3DS and will they work?
