Never jump directly from an old firmware version to the latest one without consulting the official . FortiOS upgrades must often be done in stages (e.g., moving from 7.0.x to 7.2.x before going to 7.4.x) to ensure that your configuration file translates correctly without corruption. Always review the Release Notes for known issues and hardware compatibility. Step 2: Perform a Complete Backup

Backup Configs : Save your configuration before any reboot. Read Release Notes : Check for "Known Issues" per model. Test in Stages : Update lab units before production gear.
A key concept to understand is Fortinet's firmware maturity levels. Versions with a maturity, like 7.6.0, introduce new capabilities but may have stability issues. "Mature" (M) releases are more thoroughly vetted and recommended for production environments.
Once the firmware installation is complete, verify system stability by checking: Interface and routing table status. VPN tunnel connectivity (IPsec and SSL-VPN).
Fortinet’s proprietary operating system, FortiOS, serves as the software foundation for FortiGate Next-Generation Firewalls (NGFWs). Fortinet routinely balances two primary tracks of firmware releases:
