Introduction to “Cisco_Meeting_Server_3_7_vm-upgrade.zip” Software

This upgrade package enables seamless migration of Cisco Meeting Server (CMS) deployments from versions 3.4 to 3.7 on virtualized environments, including VMware ESXi 6.7+ and KVM hypervisors. Released in Q3 2023 under Cisco Collaboration Software Release 14SU2, it addresses critical interoperability requirements with Webex Hybrid Media Services while maintaining backward compatibility with SIP/H.323 endpoints.

The package supports CMS clusters requiring enhanced security compliance (FIPS 140-2 Level 1 validation) and optimizes resource allocation for deployments exceeding 1,000 concurrent HD video sessions. Compatible systems include Cisco UCS C240 M5 servers and VMware vSphere 7.0+ environments with minimum 32 vCPUs/128GB RAM per node.
