​​Legacy System Considerations​​


Organizations running FortiOS 5.x must first upgrade to 6.2.9 before applying this update. The 6.4.3 branch maintains backward compatibility with configurations created in FortiOS 6.2.x, though certain deprecated features (e.g., PPTP VPN) will be automatically disabled during installation.




​​Post-Installation Recommendations​​


    

  1. Conduct full policy backup through FortiManager before proceeding
    2. 

  2. Schedule maintenance window during off-peak hours (minimum 45 minutes required)
    3. 

  3. Verify IPS engine version 6.00192 or newer post-upgrade
    4. 



This firmware remains supported until Q2 2026 per Fortinet’s product lifecycle policy, with quarterly security patches expected through 2025.
