You can go straight. 

Just make sure you read the Release Notes.  You may need to load the Supplementary AP Bundle.

thanks, fo update

 

 

in case of N+1 redundancy what is the best scenario to start IOS upgrade and for ap bundle should be installed before IOS upgrade and reboot or after?

 

for mesh AP it will download the image since their images included only in ap bundle upgrade?

 

and after IOS upgrade for N+1 scenario, i have to reconfigure the AP groups?

For N+1: 

  1. Upload the firmware
  2. DO NOT REBOOT the controller
  3. Upload the Supplementary AP Bundle
  4. [OPTIONAL] AP Pre-Download
  5. Reboot controller
