Troubleshooting Tip: Unable to Restore/Migrate FortiManager/FortiAnalyzer Configuration with Error: Failed to restore all settings (private-data-encryption must be enabled with the same key)

Users may encounter failure when trying to restore or migrate the configuration backup into FortiManager or FortiAnalyzer.

To find why the restore/migrate fails, users can check the Alert Message Console widget under Dashboard -> Alert Message Console, or the Event Logs under System Settings -> Event Logs.

In the example below, the error message 'Failed to restore all settings (private-data-encryption must be enabled with the same key)' can be seen. 

This error message means that the configuration backup that was taken previously had the configuration 'private-data-encryption' enabled, while the current configuration does not have 'private-data-encryption' enabled (or it is enabled with an incorrect encryption key).

To enable this, enter the following command into FortiManager/FortiAnalyzer:

config system global

    set private-data-encryption enable

end

Please type your private data encryption key (32 hexadecimal numbers):

<private key>

Please re-enter your private data encryption key (32 hexadecimal numbers) again:

<private key>

Once the configuration has been enabled, the restore/migrate process should be successful.
