So I'm looking at upgrading to one of the new MBPs when they come out. This will be the first time I've upgraded my computer while apart of the iOS developer program. So my question is, how do I go about migrating my stuff without losing my certificates, private keys, etc? I have already exported my private keys but I want to make sure I get this done right. I would hate to lose my ability to submit apps So, if anyone has gone through this process successfully, could you please give me a step by step procedure of how you did it? Thanks!
