Always keep FortiOS up to date. The most recent version is the most stable and has the most bugs fixed and vulnerabilities removed. Fortinet periodically updates the FortiGate firmware to include new features and resolve important issues.
After you register your FortiGate, you can receive notifications on FortiGate GUI about firmware updates. You can update the firmware directly from the GUI or by downloading firmware updates from the Fortinet Support website.
Before you install any new firmware, be sure to follow these steps:
- Review the release notes for the latest firmware release.
- Review the Upgrade Path tool to determine the best path to take from your current version of FortiOS to the latest version.
- Back up the current configuration.
Only FortiGate administrators who have read and write privileges can upgrade the FortiOS firmware.
