There are no tables, per se, created by OPC's installation script ... just additions to the database's configuration, customers and address_book tables.
The live site's database is upgraded to zc_install and then I bring over all of the customer, order and related tables to "refresh" the dev site's data. Then it's just a matter of moving the live (in maintenance mode) site's files out and the new files in. Right, I need to then add the changes for customers and address_book tables.
