Best Practices for Upgrading FortiGate Firmware
Here are some best practices to keep in mind when upgrading your FortiGate firmware:
As of the latest vendor release notes and internal stability testing, the following versions are recommended for deployment:
Most failures occur because users skip intermediate versions. If you are on 7.0.x, you cannot jump to 7.4.6. Follow Fortinet’s upgrade path tool (available on the Customer Service & Support portal). A verified upgrade requires stepping through 7.0.12 -> 7.2.9 -> 7.4.3 -> 7.4.6. Latest FortiGate Firmware Versions As of my knowledge
Once you have identified the target version (e.g., 7.4.6), follow this deployment script:
Before you even look at features, you must verify the file you downloaded hasn't been tampered with. Fortinet signs all firmware images with a GPG key and provides a SHA-256 checksum.
Just because a firmware is “verified stable” doesn’t mean it’s secure. Cross-reference the firmware’s release notes with the latest PSIRT advisory (e.g., FG-IR-24-012). If the “latest” firmware does not patch a critical SSLVPN buffer overflow, it is not the right choice. Verified means both secure and stable.
A final critical nuance: For hardware reaching end-of-life (EOL), the latest firmware is frozen. For example, the FortiGate 60D (EOL) has a final firmware of 6.0.17. That is the latest available, but it may not be the latest verified for security. If you are running EOL hardware, your only verified path is to migrate to newer hardware (60F or 70F) running 7.4.6.
