The primary unit pushes the firmware image to the secondary (subordinate) unit first. The secondary unit updates and reboots.
The tool will display all intermediate versions you must install sequentially to reach your destination. For example, upgrading from 7.0.12 to 7.6.6 might require stepping through 7.0.15, then 7.2.10, then 7.4.11, and finally 7.6.6. fortigate firmware
Cybersecurity is an arms race, and firmware updates are your primary ammunition. Fortinet’s PSIRT regularly discloses vulnerabilities affecting FortiOS, and threat actors aggressively scan for devices that remain unpatched. The primary unit pushes the firmware image to

, known officially as FortiOS , serves as the foundational operating system powering Fortinet’s Next-Generation Firewalls (NGFWs). Far from being a simple hardware controller, it is a highly sophisticated, security-hardened software ecosystem that integrates advanced networking capabilities—such as Secure SD-WAN—with deep packet inspection, AI-driven threat intelligence, and zero-trust access control. Managing this firmware correctly is the single most critical factor in preserving your organization's perimeter security and network uptime. 1. Understanding FortiOS Architecture
