+1 We have upgraded 750 CPE’s and AP’s and have had no issue. Actually helped other issues.

In both CPE and tower to tower backhauls with beams, bridges, and rockets. Moving from 5.5.4 and 5.5.8 to 5.5.10 I have never had an issue. Ofcourse, I always reboot prior to firmware update, then after firmware update. Cover your bases and no truckrolls shall befall you.
