Firmware upgrade / downgrade path
Upgrading from earlier versions
Upgrading directly from FortiRecorder 6.4.x to 7.2.4 is supported. For earlier versions, upgrade consecutive versions to FortiRecorder 6.4.0 first, and then upgrade to FortiRecorder 7.2.4.
|
If you are upgrading to FortiRecorder 6.0.0 during this process, then make a backup of FortiRecorder 2.7.x. Otherwise you will not be able to downgrade. See details on downgrading below. If you need to upgrade FRC-400D to FortiRecorder 2.5.5 or later, first change BIOS settings so that you can perform a software reboot (only the reset button is supported). Ask Fortinet Support for help with the procedure. |
Downgrading to previous firmware versions
Downgrades may cause a loss of configuration information. (New features are not supported by older versions, for example.)
Firmware image checksums
To verify the integrity of the firmware file, use a checksum tool and computer the firmware file's checksum. For example, you could use certutil on the Windows command line:
certutil -hashfile firmware.out SHA512
Compare it with the checksum indicated by Fortinet Customer Service & Support:
After logging in, go to Support > Firmware Image Checksums (in the Downloads section), enter the image file name including the extension, and click Get Checksum Code. If the checksums match, then the file is intact.
