Upgrade information
Refer to the Upgrade Path Tool (https://docs.fortinet.com/upgrade-tool) in the Fortinet documentation library to find supported upgrade paths for all FortiGate models and firmware versions.
A similar upgrade path tool is also available from Fortinet Support: https://support.fortinet.com.
See also, Upgrade information in the FortiOS 6.4.8 release notes.
In some cases, these upgrade path tools may recommend slightly different upgrade paths. If that occurs, the paths provided by both tools are supported and you can use either one.
If your FortiGate is currently running FortiOS 6.2.6, 6.2.7, 6.2.9, or 6.4.6 firmware and is licensed for hyperscale firewall features, you can follow a normal firmware upgrade process to upgrade to FortiOS 6.4.8.
If you are currently operating a FortiGate-4200F, 4201F, 4400F, or 4401F without a hyperscale firewall license, you can use the upgrade path to upgrade to FortiOS 6.4.8. Once you have upgraded to 6.4.8 you can activate your hyperscale firewall license and set up your hyperscale firewall configuration.
