This operation could be necessary for T300 version that have no longer USB port
used for backup/restore operation for example.
A firmware downgrade happens when the software's version number to be installed is less than the currently Installed software, for example, from 2.9.1 to 2.9.0.
This functionality is present from 2.9 software version of PowerLogic T300.
When a downgrade is performed, the current configuration is lost to prevent a system malfunctioning.
This functionality requires a specific RBAC version that is not installed if the software version has been previously upgraded from 2.8 to 2.9. In this case, the required object included in CAE and security policy for 2.9 version, must be added.
This functionality is only available for users with SECADM role.
