I picked up a new 2DS this afternoon, and did a data transfer from my 3DS XL. Some people would probably say this seems rather odd considering how much bigger and better the 3DS XL is, but I did it because:
Luckily the data transfer sent over everything, including my friend code, so I have no need to update anything here. This does mean I have to get used to the smaller screen again, but that's not a big deal to me.
As for the 3DS XL, I'm giving it to Dipper, as a means to thank him for everything he's done for me over the last several years. He's also had an interest in trying out Phoenix Wright, so this will give him the ability to do that too.
