Abstract

As organizations prepare for the end-of-life of Camunda 7, manual migration remains complex due to fundamental differences between the two platforms. We present Vanilla-Converter, a command-line tool that facilitates the migration of BPMN models from Camunda 7 to Camunda 8. Vanilla-Converter automates the transformation process, supports a wide range of BPMN elements, and produces a transformed model and a detailed transformation log indicating automatic changes and remaining manual conversion tasks. The tool's effectiveness is demonstrated through three case studies with real industrially used Camunda 7 models, confirming its ability to convert these models into valid and executable Camunda 8 models.
