  • Shagma

    Where is the FORTIAP upgrade path document?

  • Aleksandr

    Hello,
    Need help with searching the correct path.
    My Firmware Version v4.0,build0313,110301 (MR2 Patch 4)
    What numbers should I refer to? (4.2.4 313 >> 4.3.6 >> 4.3.11 >> 4.3.18? does build0313 equals to bild 313 from this table?)

    • bdickie

      Yes MR2 Patch 4 can also be expressed as 4.2.4 and yes 0313 and 313 are the same build. We aren’t planning on researching the optimal upgrade paths from 4.2.4. But once you get to any 4.3 build then any of the upgrade paths in the document should get you to 4.3.18 and beyond.

      • Aleksandr

        ok, thx for quick reply

  • Jorge

    Hi!
    How can I find the supported upgrade from 5.0.12 to 5.2.7? I only see the option directly to 5.2.9

    Thanks!

    • Judith Haney

      Hi Jorge, Page 11 of the Release Notes for 5.2.7 says that “FortiOS version 5.2.7 officially supports upgrade from version 5.0.12 or later” and that document can be found at this link: http://docs.fortinet.com/d/fortios-5.2.7-release-notes — Hope that helps!

      • Jorge

        Hi Judith,
        Does it mean upgrade directly from 5.0.12 to 5.2.7 is supported? Thanks for your quick answer!

        • Judith Haney

          Yes Jorge.

  • Biswarup Datta

    Hi, I have upgraded from 5.4.1 to 5.4.2. Received an error “Internet-service versioin(3) is not supported” in time of reboot. What should be the probable reason???

    • Bruce Davis

      I have not experienced or heard of that particular error before. The first thing I would do verify is what generated the error. Was it the FortiGate or were you viewing it through a browser when you saw the error.The second thing to do would be to see if your FortiGate is functioning properly. Was the FortiGate successfully upgraded? Is it properly processing traffic? Once you have this information you could contact the Technical Assistance Center for any troubleshooting or ask them to forward the question to Developement.

  • Luis Danilo Ruiz Tórrez

    Hi, I think this version should be 5.0.12

    Version: FortiGate-240D v5.0,build0318,150514 (GA Patch 12)
    Branch point: 318

    My question is, can i upgrade FG directly into 5.2.9??

    As the tables states,
    5.0.12 318 >> 5.2.9 >> 5.4.3

    After 5.2.9 then again I could upgrade into 5.4.3, is that right?

    • Bruce Davis

      As long as the firmware that you are upgrading to supports the model of FortiGate that you’re going to be running it on, you should be able to upgrade from 5.0.12 to 5.2.9 and then to 5.4.3. This does not mean that you shouldn’t bother reading the Release Notes for the versions that you are upgrading to. The table is a simplified version of what is supported. Depending on your configuration, there may be some changes that go along with the upgrade that you will want to be aware of. These can usually be found in the Release Notes.
