ARUBA Controller firmware upgrade – (Best practise)

Either way will do but if you have Local controllers deployed, as a best practice upgrade the Standby first and then Master.

1. Upgrade the image of backup partition of Standby

2. Upgrade the Image of Backup partition of Master

3. Enable ” AP Image Preload” if you want to reduce the down time

4. Reload both the controllers.

Note : don’t forget to take the flash back up of the master before doing the above.
