Can a MSE running on 5.2 code work with WCS 6.0 code?
A. It is not a supported configuration. Cisco always recommends same software release level for MSE and WCS. So 6.0 MSE/6.0 WCS; 5.2 MSE/5.2 WCS are the supported configurations. Note that WCS can manage a wireless LAN Controller, which is up to 2 releases behind the software release that runs on WCS.
