Rolling back

J F

 i am having issue with v18 speed so I want to roll back. When I try to go to install the old firmware, I get a error saying "New firmware could not be uploaded, check online....." any help would be appreciated.

    Here are the similarities and differences related to downgrade and rollback with v18 vis-a-vis v17.x and earlier:

    Support for downgrading to older firmware:

    • Devices running v17.5 or earlier: Downgrading using firmware upload is supported. However, when downgraded the device will boot up in the factory default configuration state (the Web console will give the appropriate alert before you continue). Administrators can restore the downgraded firmware's backup.
    • Devices running v18 or later: Downgrading using v17.5 or earlier firmware is NOT supported (the Web console will the give appropriate message). v18 uses Grub boot loader. The changed bootloader cannot recognize v17 firmware. Administrators can still use the hardware ISO of v17.5 or an earlier version to get the firewall on an older firmware version and restore the downgraded firmware's backup.

    Support for rollback (firmware switch) to older firmware:

    • Firmware switch/rollback is supported as usual. As an example, the active firmware on the firewall is v18, and the second firmware version is v17.5. Administrators can switch between these two and the configuration on each will stay as it is.

    Recommended upgrade process when you test multiple v18 early access releases:

    • This is applicable if you have upgraded to v18 from v17.5. When you upgrade from v18-EAP(x) to v18-EAP(x+1), you can first switch to v17.5 and upgrade from v17.5 directly to v18-EAP(x+1). From there, you can then restore the backup of v18-EAP(x). This way you will always have v17.5 firmware in your second firmware slot, and leave an option open to roll back to v17.5 if needed.
