Export / Import Symantec Management Platform Security Roles

I have a demo environment where I have created and customized some security roles. I now want to export the roles and import them in my production environment, however when I use the right click export and import or the import/export utility under the notification server > bin > tool directory, the roles import but with no permissions or access that was assigned. is there a way to import and export security roles, I have follows the below post with no success: https://www-secure.symantec.com/connect/forums/smp...

I also want to use the export and import as means of a backup.
