Hi, i purchased a wii u on launch date back in 2012. I created a nintendo network id and everything and i've made some friends through miiverse. I've even linked my account to my 3DS. However, recently i've been wanting to change my nintendo network id username. Since you can't change the username, i decided i might as well create a new nintendo network id and just transfer all my information over. I'm not sure how to do this, or if it is even possible to transfer data from one id to another. I could really use some help. Also will unlinking my former account from my 3DS remove all my data from my 3DS? I don't wan't to lose my friends list or any of my save data from my downloaded games.
If any clarification is needed please tell me, i'd be happy to help
Thanks!
