Firmware upgrade / downgrade path
For firmware upgrade procedures, see the FortiRecorder Administration Guide.
Upgrading from earlier versions
Upgrading directly from FortiRecorder 6.4.x to 7.2.8 is supported. For earlier versions, upgrade consecutive versions to FortiRecorder 6.4.0 first, and then upgrade to FortiRecorder 7.2.8.
|
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
When you download software, use checksums to verify that the file has not been modified or corrupted.
-
On the Fortinet Support site, go to Downloads > Firmware Images.
-
Select FortiRecorder
-
Click the Download tab and then click to go into the version folder.
-
Next to the file, click HTTPS to download the file. Then click Checksum to show the file's checksum.
To verify the file's integrity, the checksum shown by the website should match the checksum of the file on your computer.
-
Use a checksum tool and compute the firmware file's checksum. For example, you could use certutil on the Windows command line:
certutil -hashfile firmware.out SHA512
If the file's checksum shown on the Fortinet Support website matches the file's checksum on your computer, then the file is intact.
