Delete Test Data
This page gives you a quick and easy way to "flush" test data such as products, customers and orders out of your database before you take your site live. You can select what data you want cleaned out of your database and then click "Start Cleanup".
Warning: There is no way to undo this procedure, so make sure you are certain you want to continue before doing so. It would also be a good idea to make a backup of your database just prior to performing the clean up, just in case.
