Introduction to Cisco_Secure_FW_Mgmt_Center_Upgrade-7.3.0-69.sh.REL.tar

This software upgrade package enables seamless version migration for Cisco Secure Firewall Management Center (FMC) physical appliances and virtual deployments. Designed for administrators managing distributed firewall infrastructures, the 7.3.0-69 release focuses on operational stability and security compliance for hybrid network environments.

Compatible with FMC 1700/2700/4700 hardware models and FMCv300 virtual appliances, this upgrade maintains centralized control over Firepower Threat Defense (FTD) devices while introducing critical vulnerability patches. The package contains validated binaries for systems running FMC 7.2.x versions, with automated dependency resolution during installation.
