Flushing VWO test data allows you to clear the test data that your test has collected previously. Using this option, you can typically make any modifications and start the test all over again, collecting data from scratch.
If a visitor has already become part of the test, the VWO cookies are stored in the visitor’s browser. This typically means that the visitor is not tracked again, and the same variation is displayed to the visitor as before. However, if the visitor converts during the second visit, the conversion is tracked. Thus, VWO will not track visitor data for the same visitor but will record conversions if the visitor converts during the second visit.
For example, say a visitor has become a part of your test (but not converted) before you flushed the data. Now, if you flush the data and the same visitor returns to the same test and converts this time, VWO will record a conversion but not the visit because the VWO cookies are already in the browser. Thus, you may see a report that displays visitor count as Zero and conversion as 1.
Each cloned test will have a new ID and new cookies are created for all the visitors, without having to worry about tracking previous visits or conversion data.
