## Upgrading from FusionCharts v3 Evaluation
This section is meant for users who have implemented the Evaluation version of FusionCharts in their application, and are now upgrading to the commercial license. There is no feature limitation/difference between the evaluation version and the commercial version of FusionCharts, but for the fact that the evaluation version has "InfoSoft Global" and "FusionCharts" stamped over all the charts. If you have been using the evalution of FusionCharts in your application and are now upgrading to a commercial license of FusionCharts, you'll need to do the following: Replace Evaluation version SWF with the new purchased SWF Files (present in Download Package > Charts folder). Clear your browser cache - very important step. When you now view your application, you would not find any stamps on your charts.
