I have a question concerning my 2DS SD card.
Today I went back to Gamestop where I bought my 2DS. My old 2DS had a small detail that allowed me to exchange my 2DS for a new one through my waranty. I was not aware that once a Nintendo Network ID is linked to a system, you can't use that account on another one (Thus I can't use it on the new 2DS).
Now, during the exchange, the person at Gamestop switched the SD cards between my old and new 2DS meaning that now I have a new 2DS with my old SD card. Before I had realized that I could no longer use my old account, I proceeded to make an update to the system.
This is my question now: Will I still be able to make a System Transfer after having this occured? The manager at Gamestop has allowed me to go back and do the system transfer at a more convenient time for the store, but my concern is that it will no longer be possible now that I have done an update my this new system while using my old SD card.
