Use the Fortinet Documentation Library or the FortiGuard Upgrade Tool to determine the supported upgrade path.

However, the power of FortiOS brings with it the critical responsibility of lifecycle management. The management of FortiGate firmware is a discipline that separates a secure network from a vulnerable one. Fortinet operates on a predictable lifecycle model, categorizing firmware releases into "Feature" releases and "Mature" releases. Feature releases introduce cutting-edge capabilities but may have a shorter support window, making them suitable for organizations seeking the latest innovations. Conversely, Mature releases prioritize stability and long-term support, catering to mission-critical environments where uptime is paramount. The necessity of regular patching cannot be overstated; because FortiOS sits at the network perimeter, it is a high-value target for threat actors. Vulnerabilities within the firmware itself—though rare due to Fortinet’s rigorous testing—can expose the entire network. Therefore, the process of upgrading firmware is not merely a maintenance task but a strategic imperative to close security gaps and ensure compatibility with the latest threat intelligence feeds. fortigate firmware
