I have several cisco AP1562i AP's one of them is also acting as a AP and as the WLC for al the AP's.
They are all running 8.3.122.0 and I wanted to know how would I go about trying to upgrade them all. I read that I would need to upgrade the WLC, then that would upgrade the AP's but on the GUI there is no option to upgrade the WLC.
Would I have to upgrade the WLC via the cli only.
Many Thanks
In advanced
