Cisco ACS 5.8 VMware Base License Upgrade

Upgrade Cisco Secure Access Control System deployments from version 4.2 and earlier to 5.8 on VMware with base licensing included. This license is built for organizations that need to modernize access control without rebuilding the operational model from scratch. By moving to a newer ACS release, teams can keep authentication and policy workflows aligned with current infrastructure standards while preserving the continuity that matters in production security environments. The VMware deployment model supports virtualized operations, making it a practical fit for teams consolidating security services into managed infrastructure. This is a targeted upgrade path for environments that already depend on Cisco ACS and need a clean transition forward. It is especially relevant for security teams that value controlled change, predictable licensing, and a clear migration step from earlier releases.
