Solved: 8540 WLC Software Upgrade

osamaibrahim_2011 · ‎04-25-2021

Hi,

I have 8540 WLC with 8.5.135.0 software version, I'm planning to upgrade to the latest stable version, would you advice which is the stable version, in addition can I upgrade directly from 8.5 to 8.9 or 8.10?

thanks,

8.10 is a stable version. you can directly upgrade from 8.5 to 8.10

read the release notes check the compatibility with your AP and caveats/Bug

Go straight to 8.10.X.X.

NOTE: Is the CIMC connected to the network or not?
