What strategy are people using for managing firmware updates? We have ePMP and PMP devices in our environment. We will probably also add some cnWave.
Upgrade all devices as soon as a new firmware version is posted?
Apply critical firmware updates only?
Apply updates mainly if a problem warrants it?
I’m hoping to minimize administrative overhead and the possibility of device downtime.
Test on some device, wait one or two weeks if everythink work well update others.
Meantime read forum and get knowladge about possible problems 
Newer cnMaestro requires a minimum version on the radio device, so we’ve updated because of that. Otherwise, find a stable version and run it until a better, stable version comes out. All MFGs have bugs, the difference is the cost of the bug.
