I've got a Japanese 3DS that I have replaced with a US model. I'd like to be able to move all my data to the US one, but the transfer does not seem to work. I've followed all the steps, but the systems simply sit there scanning for the other device with no luck. I let it run for minutes and there was no timeout.
So, is it possible to do? I couldn't find any information on this special case.
@YoungFrey: Oh man that is a tough one, I'm edging to saying that it is not possible because the system transfer moves over e-shop purchases which are region locked.
I gave their troubleshooting site a quick look but no luck there.
Best would be to simply ring them up http://www.nintendo.com/corp/contact.jsp

@YoungFrey: You can just drag the files off one SD card onto another.... so I suggest you trying that.
As what Rallier said though, anything region locked won't work.
Thanks for the help everyone. It wasn't what I wanted to hear, but it's nice to get an actual answer.
