Since I just got a new rMBP with 802.11ac, I am considering upgrading my Time Capsule to the new model. Two questions, though. 1.) Will my new rMBP get the "ac" speeds or will Time Capsule default to "n" speeds if there are other devices on the network not with an "ac" card? In other words, does it support a mixed environment? Most of my "n" devices are on the 5GHz frequency. Only a few older devices are on the 2.4GHz network. 2.) Is there a way to take my current Time Capsule settings and import them to the new machine? My current configuration would be very time consuming to set up a second time.
