While VMS and LAN Management Solution (LMS) can coexist, it is recommended that they reside on separate servers for optimal performance. Cisco Threat Response is not compatible with VMS 2.2 installs. You must first uninstall Cisco Intrusion Detection System Host Sensor (HIDS) before you can install Cisco Security Agent (CSA) Management Center (MC). Because there cna potentially be incompatibilities between Cisco HIDS and CSA MC or agent software, you must uninstall the Cisco HIDS and Cisco HIDS Console software before installing CSA MC or its component "agent" software.
