Hi, I currently have the 2012 MacBook Air 13.3" which I'm about to sell in order to buy the 2013 version. I'd like to migrate all my files to my future new Airbook so I wanted to ask a question. Would it work to just backup my current Mac to an external HDD and then restore the files on the new Mac using that backup? I'm asking this because I'm not sure, and would really appreciate if someone confirmed this. Thanks.
