Is it normal to lose all of your configurations when updating the firmware???
Generally speaking, the configurations won't be lost after updating the firmware unless there is a large change made on the new firmware.
For EAP225-Outdoor, all the settings will be lost after we upgrade from 1.7.0 Build 20200113 or earlier (non-SDN firmware) to 1.20.0 Build 20200422 or later (SDN firmware). If your configurations are lost after the firmware update, it might be that you are upgrading the EAP225-Outdoor from non-SDN firmware to SDN firmware.
