cisco ap 9115 IOS upgrade

[heyjunsun]

Hi, I am upgrading my Cisco 9115AXI AP from 16.02.04.a to the recommended version.

The upgrade failed at first, so I switched to u-boot mode and successfully booted with Bundle IOS.

What I'm curious about is that if you want to install the recommended version of EWC mode in the current state

8.10.130.0 --> 8.10.190.0 --> 17.6.6 CAPWAP --> EWC images?

Do I have to install EWC images sequentially like this? I tried to install 17.09.04a from 8.10.130.0 at once and failed.

If you know the IOS installation guide or installation order, please let me know

Hello, 

what was the reason for the failed upgrade?

Please check the compatibility matrix - https://www.cisco.com/c/en/us/td/docs/wireless/compatibility/matrix/compatibility-matrix.html

Installing directly therecommended version of EWC mode should be a problem.

@heyjunsun you've already discussed this at great length on https://community.cisco.com/t5/wireless/cisco-ap-ios-update/td-p/5020257 - why are you duplicating the questions here?

You are welcome to do it anyway you want if you don't like my advice. 
But I've suggested the upgrade path which I have found works reliably.

hello rich ! 

Thank you for your reply.

I wrote it twice because I was in a hurry. I didn't write it because I didn't like your question. Don't get me wrong! I solved the problem thanks to you. Thank you.
