FortiGate-6000 and FortiGate-7000 Release Notes

HA graceful upgrade to FortiOS 6.4.2

Use the following steps to upgrade a FortiGate-6000 or 7000 HA cluster with uninterruptible-upgrade enabled from FortiOS 6.2.3 or 6.2.4 to FortiOS 6.4.2.

Enabling uninterruptible-upgrade allows you to upgrade the firmware of an operating FortiGate-6000 or 7000 HA configuration with only minimal traffic interruption. During the upgrade, the secondary FortiGate upgrades first. Then a failover occurs and the newly upgraded FortiGate becomes the primary FortiGate and the firmware of the new secondary FortiGate upgrades.

To perform a graceful upgrade of your FortiGate-6000 or 7000 from FortiOS 6.2.3 or 6.2.4 to FortiOS 6.4.2:

  1. Use the following command to enable uninterruptible-upgrade to support HA graceful upgrade:

    config system ha

    set uninterruptible-upgrade enable

    end

  2. Download FortiOS 6.4.2 firmware for FortiGate-6000 or 7000 from the https://support.fortinet.com FortiGate-6K7K 6.4.2 firmware image folder.

  3. Perform a normal upgrade of your HA cluster using the downloaded firmware image file.

  4. Verify that you have installed the correct firmware version. For example, for a FortiGate-6301F:

    get system status
    Version: FortiGate-6301F v6.4.2,build1749,201119 (GA)
