In recent years, development within the Java ecosystem has accelerated. Whether it's Java SE, Jakarta EE or Spring Boot, releases and end-of-support messages are coming thick and fast. The number of necessary migrations is increasing rapidly and there is constant pressure to implement new features.

The open-source tool OpenRewrite can automate and scale migrations for projects. The large and growing number of ready-made migrations provides solutions for a wide range of situations. Additional requirements can be implemented quickly thanks to the configuration and combinability of existing migrations. More complex adaptations can be easily implemented thanks to the direct integration of Refaster templates.

This session will cover the range of OpenRewrite's functions and its integration into existing projects. The fundamentals of test-driven migration development will also be covered. Participants will learn the fundamentals of OpenRewrite and receive valuable tips for everyday use.

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