Unfortunatly there isn't, since a lot of other things are stored in the database as well (permissions, groups, users, reports, etc). I would suggest to close all the open test incidents. Your customized work flows can be re-published, so if you didn't made to much changes in the portal, document all your changes and do a re-install, name the database "processmanager_new" that why you can still look at the orginal database.
