I've been away from AREDN for quite some time, life and the pandemic got in the way, I have a number of older Ubiquiti systems still running on earlier versions of firmware (3.16 and 3.19). Are there any gotchas I need to be aware of going to the latest version, and can these older systems (all are most likely on the sunset list) even run the newer firmware? Systems included (all are M2 2.4 GHz devices) AirGrid M2, Bullet M2, Nano Loco M2, and one AirRouter M2.
