1)Plan for and install the Catalyst WiSM.
2)Install the Catalyst WiSM platform.
3)Install the Cisco Wireless Control System (WCS) network management platform for the Catalyst WiSM.
4)Migrate the configurations from the Catalyst WLSM to the Catalyst WiSM-based platform to continue support of all lightweight and converted autonomous access points.
5)Train the support personnel on the Catalyst WiSM platform and solution.
6)Clean up the legacy configurations when the migration is complete.
