[Ashok09]

Hi 

My Wi-Fi Network setup is mixed APs model. when we are trying to update the Firmware through EWC - HTTP method is not possible because the non homogenous  model. 

Suppose i try to update the firmware via TFTP. the updated image is running in the backup Image.

Did anyone having this similar issues ?

 - The question is a bit confusing ; if you refer to client AP upgrade(s) connected to EWC check :

                          If not , please elaborate ,

Thank you very much for your support and link

I have updated through web / GUI -> tftp method. But some of the AP's not able to update so used cli and then activated. 

archive download-sw /no-reload tftp://192.168.XXX.XXX/C9800-AP-universalk9.17.09.04/ap3g3

How did you do the upgrade?
As soon as you change the EWC version the subordinate APs will be triggered to download and switch to the new version.
