FortiGate Upgrade Paths

If you are looking to upgrade your FortiGate to the latest version of code you need to stop and read the links listed below. There is a supported upgrade path for each version of FortiOS (4, 5, 5.2, 5.4, etc). If you want to progress through the versions of code without nuking parts of your config or causing yourself to experience strange explainable behavior (that’s a trick question since it is definitely explainable….you didn’t follow the upgrade path!) then you please follow these instructions.

Click the link below and scroll down to the “The Upgrade Path Tables”. This page will tell you how to get to the version of code that you wish in a safe and secure manner!

  1. Looks like Fortinet removed this table from the iNet recently and are advising to use their upgrade path calculator on However, the calculator will only display upgrade paths from v5.2.9 and does not even include v5.4.8. I cannot find a cached version of the Cookbook table anywhere. Do you by chance have a copy?

    • Kevin,

      Unfortunatley, I do not. I have always used the table. The calculator does seem to have some issues that they will hopefully resolve. I will ping some of my friends and see if they can provide any insight.

    • It looks like you can use the tables linked in the article to upgrade to the latest 5.2 build, then use the upgrade path calculator on the support site to upgrade from there.

  2. Having the same issue here… Just found an old FGT 60c running 5.2.4 and therefore as per their firmware upgrade patch it start at 5.2.9 and can’t got further than 5.2.13 :/
