In recent years, development in the Java ecosystem has accelerated. Whether Java SE, Jakarta EE or Spring Boot - the releases and end-of-support messages are chasing each other. The number of necessary migrations is exploding and the feature pressure is not letting up.

With the open source tool OpenRewrite, migrations can be applied to projects in an automated and scalable way. The large and growing number of ready-made migrations offers solutions for many situations. Additional requirements can be implemented quickly thanks to the configuration and combinability of existing migrations. More complex adaptations are easy to implement thanks to the direct integration of Refaster templates.

This session covers the range of functions and the integration of OpenRewrite into existing projects. The basics of test-driven development of migrations will also be covered. Participants in this session will learn the basics of OpenRewrite and receive valuable tips for regular use.

A demo guided tour through the basic features of OpenRewrite needed for basic Migration Engneering Tasks.
