We have a 4402 with S/W 3.2.150.6 and want to upgrade to 4.0.217.0 to match other controllers. We use APs which were converted to LWAP. My concern is, will the WLC 'forget' the self signed certificates it got when the APs were converted?
They are AP1220 which were hardware upgraded by replacing the radio card (P/N AIR-MP21G-A-K9) which makes them AP1231G.We also had to convert them from VxWorks to Cisco IOS then convert them to LWAP.
