How to Export and Import Profile Types

I need to copy the Profile Types, with all custom fields (not test users), from my test installation to the production installation. Both installs use ES 1.3.15. They are located in different subdirectories on the same server. Is there a way to export the settings from the test to the production. In phpMyadmin, I see all of the tables but could not determine which table contains the Profile Type custom fields.
