Before you begin: plan and prepare
- Check release notes: Read the release notes for the target firmware version. Note fixed issues, known issues, and upgrade caveats.
- Compatibility matrix: Verify your FortiGate model and hardware revision support the firmware build.
- Backup config: Export the current configuration (GUI: Dashboard → Backup → Local/Remote, or CLI: execute backup config). Store it securely.
- Maintenance window: Schedule a maintenance window—upgrades typically cause a brief outage during reboot.
- Read downgrade notes: Some firmware upgrades change config formats; downgrading may require manual interventions.
- Lab or test unit: If possible, test the upgrade on a non-production unit first.
- Check licenses and services: Ensure your FortiGuard and other subscriptions are active for feature continuity.
- Ensure console access: Have serial/console access ready and administrative credentials in case the GUI/SSH becomes inaccessible.
- Disk space and HA considerations: Check system resources and, if in HA mode, follow recommended sequence (see below).
4) Verify firmware integrity
- If the vendor provides checksums (MD5/SHA), verify the downloaded file:
- Do not proceed if checksums mismatch.
