What exactly are you asking? Do you want to know how to do a system transfer? Just choose system transfer from the settings on each and follow the prompts. I would recommend choosing the move data manually option, then when it's done, copy over your Nintendo 3DS folder and anything else you need onto the microSD of the N3DS. Any non legit CIAs will need to have their tickets installed on the N3DS to show up on the home menu (use CIAngel for one by one or TIKdevil for all at once).
