Customer Area -> Get Support Center -> Get Support HelpDesk -> Exclusive Professional Services -> Backup Restore
In addition, you could request an Application upgrade, by posting a ticket under:
Customer Area -> Get Support Center -> Get Support HelpDesk -> Exclusive Professional Services -> Application Upgrade
