I am considering getting a new Airport Extreme (tower). I am currently utilizing an Airport Extreme (model A1354, version 4) and am using use static addressing with many MAC addresses configured. I have exported and saved the config file for my current Airport Extreme. When I purchase the new Airport Extreme (tower), can I simply import the config file into the device and be on my way, or is the software on the new device different and save config files in a different manner?
