I have 10 1200 wireless AP running. I just bought 3 1300 wireless bridge. They will do the same as 1200. Here is the configuration just in a case you like to check it: Sample of Cisco 1200 Access Point
I can copy the configuration of 1200 to 1300?
Most of the commands should take. But since I am unsure of the IOS versions you may have one or two commands that are unaccepted by the 1300.
All in all...it should take and be operational to the 1200's spec.
