I am going to upgrade my WISMs to 6.0.188 from the GUI. In the install notes it say's to shut down the controller port-channel.
When I do so I can't get to the controllers to start the download. If I download the new IOS will the controller
automatically reboot? If so not sure how this would be done. Do you shut down the port channel after the re-load starts?
Thanks for the help!
What you should do is move your ap's off one of the WLC's and then upgrade that WLC to 6.0.188. Then move AP's
back to that WLC making sure everything works. then move all you ap's to the upgrade
WLC and upgrade your other WLC on that WiSM. You will have to reboot the WLC after the upgrade though.
