The "EPC to BPMN" feature is a tool that allows users to convert process models created in Event-Driven Process Chain (EPC) notation into Business Process Model and Notation (BPMN) notation.

To utilize this feature, first select the EPC model that you want to convert. Then, select the "Report" icon from the toolbar, and select the option to "Convert EPC to BPMN."

A dialog window will open. Select a destination folder for the conversion and click "Save" to begin the conversion process. Once the conversion is complete, the resulting BPMN model will be saved in the destination folder that the user selected.

You'll also have the option to choose between "application-oriented" or "role-oriented" conversion.

Application-oriented conversion is focused on the process flows and their functions, while role-oriented conversion is focused on the roles of the people involved in the process and their interactions.

You should select the option that aligns with your needs and the purpose of your process model.

It's important to note that the conversion process may require some manual adjustments to ensure the resulting BPMN model is accurate and complete. So, make sure to check the converted model carefully and make any necessary adjustments.
