Introduction to Cisco_Meeting_Server_3_8_vm-upgrade.zip
This critical upgrade package enables seamless version migration for virtualized deployments of Cisco Meeting Server (CMS) 3.8, Cisco’s enterprise-grade collaboration platform. Released on September 7, 2023, the 676.09 MB ZIP archive contains essential components for updating existing CMS virtual machines on VMware vSphere environments. Designed for organizations maintaining hybrid conference solutions, it preserves configuration continuity while implementing critical security and performance enhancements.
The package specifically supports CMS deployments requiring compatibility with Cisco’s Webex ecosystem and third-party SIP endpoints. Administrators managing multi-node clusters for large-scale video conferencing will benefit from its optimized resource allocation protocols and backward compatibility with CMS 3.6+ environments.
