AirPort Utility 6.3 for Mac
Apple has released AirPort Utility 6.3 for Mac, which adds compatibility for the just-released 802.11ac-enabled AirPort Extreme and AirPort Time Capsule models (see “Apple Releases Longer-lasting MacBook Air, Faster AirPort,” 10 June 2013). If you don’t have the new hardware, there’s no reason to get the update. Concurrently, Apple released the AirPort Base Station and Time Capsule Firmware Update 7.7.1, but it is available only for the new 802.11ac base stations, resolving a rare problem that could cause a connected hard drive to become unresponsive. (If you don’t have either of the
new base stations, this firmware update won’t appear in AirPort Utility for you.) Finally, version 1.3 of the AirPort Utility for iOS has also been released, but it’s another one to skip unless you have one of the new 802.11ac-enabled base stations. (Free, 21.43 MB)
I have a new TC ac and a new Air 13, and still using my 500GB TC, when do I upgrade? I think it means hooking up the new TC and then upgrading the Airport Utility. My plan is to use this as a guide:

update: support guide didn't work for me so went wireless, appx. 95 GB transfered in 2 hours and 4 minutes. Thanks for the heads up , I did the 7.7.1 update before the transfer and all worked smoothly.
