Changing serial # on AP configuration

[Don1]

Is it possible to change just the serial number for WS-AP3865E series AP throught the NAC GUI and keep the existing configuration?

I have the same issue. I have 2 APs configured. I wanna download the configuration of each AP, so if an AP gets faulty to replace it and upload its configuration. Could you please explain me step by step the procedure for downloading the back up of each AP, and for uploading it? Thanks!
