I'm currently looking to upgrade the firmware running on our WLCs (due to cisco-sa-20090727-wlc) and as a consequence of this, will also need to upgrade the software version on our WCS. The current versions we have in place are:
From an upgrade perspective, I was originally looking at upgrading the WLCs to vers 22.214.171.124 before realising this also required an upgrade of the WCS. I know this could be quite an open ended question, but does anyone have any receommendations on firmware versions for the WLC and WCS platforms. Ideally I'd like to stick to Vers 4 for the WLC as we're currently running on this, with very few issues. Would it be worthwhile to upgrade the WCS to the latest available version, as this supports 126.96.36.199 or would people see this as too significant a jump.
188.8.131.52.0 on the controllers is a good idea. Really your current WCS doesn't support your controller since the WCS is 4.1 and the controller is 4.2. WCS will support the previous two major versions of controllers. Since your current WCS is older than your controllers I'm surprised you aren't getting errors already.
