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:
WLC - 126.96.36.199
WCS - 188.8.131.52
Aps Models - 1231AG and 1242 AG.
From an upgrade perspective, I was originally looking at upgrading the WLCs to vers 184.108.40.206 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 220.127.116.11 or would people see this as too significant a jump.
