    Fortinet Security Fabric upgrade

    Fortinet Security Fabric upgrade

    FortiOS 6.4.6 greatly increases the interoperability between other Fortinet products. This includes:

    • FortiAnalyzer 6.4.6
    • FortiManager 6.4.6
    • FortiClient EMS 6.4.3 build 1600 or later
    • FortiClient 6.4.3 build 1608 or later
    • FortiAP 6.4.4 build 0456 or later
    • FortiSwitch 6.4.5 build 0461 or later

    When upgrading your Security Fabric, devices that manage other devices should be upgraded first. Upgrade the firmware of each device in the following order. This maintains network connectivity without the need to use manual steps.

    1. FortiAnalyzer
    2. FortiManager
    3. Managed FortiExtender devices
    4. FortiGate devices
    5. Managed FortiSwitch devices
    6. Managed FortiAP devices
    7. FortiClient EMS
    8. FortiClient
    9. FortiSandbox
    10. FortiMail
    11. FortiWeb
    12. FortiADC
    13. FortiDDOS
    14. FortiWLC
    15. FortiNAC
    16. FortiVoice

    If Security Fabric is enabled, then all FortiGate devices must be upgraded to 6.4.6. When Security Fabric is enabled in FortiOS 6.4.6, all FortiGate devices must be running FortiOS 6.4.6.
