I want to sell my 4th gen Time Capsule and get a 5th gen one to take advantage of the 802.11ac with my new iPhones and iMac. I'm not sure how to go about it. Do I buy the new one first and then transfer the data from the old one onto the new one? (how do I do that?) How do I securely 100% wipe the data on the old one? What's the best venue to unload the old one once it's wiped? Ebay? As far as I can tell Gazelle etc., don't buy AirPorts or Time Capsules. It's a 5th gen and it's in flawless condition, never had any issues or anything, still have the original box and peripherals with it so it shouldn't be too hard to unload right? Thanks for the advice.
