I'm planning on opening a store soon and wanted to know what would be the best way to start with a fresh database (and order #1 as opposed to all the tests I ran).

Should I start a new database?
In order to do this I just have to change the config files to connect to the new database right?
Do I need to run the zcinstall again - upgrade database?
Also could I make sure this database is fine by just creating a customer account? Or is it advisable to at least run one order through the new database?

Changing the database doesn't affect my settings in admin does it?

Thanks in advance
