Clearing the Agile database after testing and preparing it for production.

We have a fresh install of Agile 9.3.4 that had no data loaded or migrated.  We followed the scripts for FDA validation and are about ready to start preparation for a production instance.  Before we started, we made a backup of the entire system.

During the validation, we made several fixes to settings and structures that we want to keep in place.  The validation created quite a bit of data that should not be carried forward to our production instance.  We would like to refresh the database but not lose the fixes we made during validation.  What is the best way to achieve this?  We don't need any history or items or any data, just an empty database using the current validated settings.
