Restoring configuration after FortiOS upgrade

Posted on 2012-08-23

Hello people,

I need to know if there's a way to convert a .cfg file (backed up configuration from FortiOS 2.8) to a .conf file - so that I can restore it to the same Fortigate unit once I've installed the latest FortiOS version.

I 've tried it in the past and had to do everything all over again cause there was no way to restore it. However this unit will take days to reconfigure and I like my job, I think I want to keep it.

So, if anyone knows something about that, I'd really appreciate any suggestions.

    You can try this process:

    To ensure you have your bases covered, I would save the .cfg file and ensure it is secured.
    Then also have a downloaded copy of the previous FortiOS version (2.8).
    This way you can roll back the changes and apply the .cfg settings if there are any issues.

    So I tried this one, and it looked like it was gonna work. Until the unit restarted and, well, it looks a bit fried. I'll have to enter as maintainer and change its password (no idea why this happened) and then check why its interfaces don't seem to work.

    Even if it needs all that, I'll still be a happy man if I get it to work.

    Well, you DID point me to what Fortinet themselves suggested, so it's only fair I give you the points.
