Ok so I am considering exchanging my 2012 MacBook Air for the Retina MacBook Pro. I have a few questions. 1. I bought it via Apple Online Store with the student discount and Back to School Giftcard, so my question is, do I need to return the gift card also? Or could they just not give me one on the RMBP purchase. 2. It was bought via "Guest" on Apple's website so I can't print an invoice, so how can I provide proof of purchase at the Retail store I'll be exchanging at? and 3rd. If all above goes well, can they transfer my data from this 2012 MBA to the Retina MBP? Thanks for the help!
