Hello team ,

im not so aware with fortigate upgrade/downgrade process.

The second part of my cluster got down because the image got crashed and i proceed with installation of another image.The previous version was 5.2.4 buld0688 - now is 5.4.2 build 1100 and my environment now use the Active node from the cluster

which is 5.2.4 build068.

The only thing  that i want to do is to downgrade the crashed fortigate  to 5.2.4 build0688 version but my roaming over internet doesnt take effect because cant find this version and build.

Does somebody can navigate me how i can take one of this images.

 

Version: FortiGate-90D v5.2.4,build0688,150722 (GA)

    I hope you know that there exitst upgrade paths?

    You cannot jump from one Version to another.

    If you read the part "Upgrading to FortiOs 5.4.2" in the Release Notes

    you will see that you must have 5.2.8 or later to upgrade to 5.4.2

     

    In your case you must upgrade from 5.2.4 to 5.2.6 then 5.2.8 and final to 5.4.2

     

    The 5.2.4 0688 Release should be available through the Service Portal.

    When you logged in and go to Downlad images you should see them.

    Hello Chris,

    the issue is that I already upgrade the affected node to 5.4.2 build 1100 and want to rollback to 5.2.4 build0688.

    Of course, i didn't follow this step and met these issues.

    And the cherry on the cake is that m organization don't have support service which directly restricts me to download images from the FortiGate portal.

    The upgrade path is designed to have a valid config so that the device will work. On every update the config will be modified if necessary. In your case the only way is to reset the device to the factory settings by formatting the device. This can be done via console (TFTP) or the FortiExplorer if it is supported. Then you have the corresponding config for this firmware release.

    This should give you a working device and it's just like using the upgrade path.

    The only difference is that you have to reconfigure it.
