I had a hell of a time upgrading from 7.4.110 to 7.6.120 on WiSM2s: 1. Crashing due to web auth, resolved in 7.6.122.6 (aka MR3). 2. Any newly provisioned AP would have its radios immediately disabled, the only apparent workaround was to manually shut/no shut the radio interfaces on the AP itself. 3. A certain mix of non-cisco PoE & cable length caused APs to only request 5W of power and leave their radios disabled, taking out large sections of wireless coverage.
To top it all, when I reverted to 7.4.121 after 36 hours of the above, the entire campus radios were disabled in a similar way to fault 2. above, eventually resolved this though. We'll be waiting for 8.0 now to support our [23]700s, and even then only after it's been released for a few months. Getting a bit fed up of beta testing Ciscos WLC code on our production network.
