Export TC Configuration?

On newer operating systems like Yosemite, Mavericks, Mountain Lion and Lion......."exporting" is easy. Unfortunately, "importing" is not easy at all .....involving a temporary Ethernet connection from your Mac to one of the LAN <--> ports on the new TC and a special "Contigure Other" setup involving the IP address of the new TC.

It would be much simpler and much faster if you used the option to "Replace an existing device". If you choose this option, all of the settings on the old TC will be automatically transferred to the new TC......and then the old TC will be reset back to factory default settings.

Another option that most users find just as easy and just as fast, if not more so, is to simply go ahead and set up a new configuration on the new Time Capsule. Having tried all 3 methods myself, setting up a new configuration is probably the simplest, easiest and fastest way to go for most users.

Up to you to decide how you want to proceed at this point.

The "Replace" option will usually do a nice job of transferring the settings over from old Time Capsule to the new Time Capsule.

HCP Reservations and Timed Access / MAC Access Control settings should all transfer over OK.

Since there is no option to adjust the Radio Mode setting on the new Time Capsule, the new device will be setup using the factory default Radio Mode for the new Time Capsule, which is a compatible 802.11ac---802.11b/g/n setting.

Let us know how things go if and when you can.
