I would consider yourself lucky if you're running 8.0.110.0 on 5508 without issue. Lots of folks I know have seen issue with 5508 crash/reboot but no crash log and the wlc either will revert back to its secondary image or not come back at all. I have opened tac case and received esc image that fixes the reboot bug. .115 has the reboot bug as well so need esc image.

Would I be wiser to wait until July or August or stay where I am for the Fall semester.
