Changing IP Range

My current subnet /26 is full and would like to change my epmp equipment and cnpilot routers to /24, what is the best way to update all at once in the shortest possible time. 1st cnPilot R-series routers (26) 2nd ePMP Force 300-22 SMs (35) and then last ePMP 3000 AP (1).

If all the devices are onboarded into cnMaestro and you’re familiar with creating custom JSON scripts with the config changes needed, that would probably be the fastest. If the radios aren’t onboarded into cnMaestro and/or you’re not familiar with JSON scripting, then with that few devices, you’re probably better off just reconfiguring them by hand.
