LevelUp your Migrations - Advanced MigrationEngineering with OpenRewrite by Merlin Bögershausen

The open source tool OpenRewrite can be used to automate and scale migrations. However, a needs analysis should be carried out before each migration. What should be done if the results of the analysis do not meet expectations or necessary steps are missing? OpenRewrite recipes can extract detailed information from the source code and provide it in the form of DataTables, which are suitable for analysis. The same API is used here as for the development of project-specific migrations. The necessary migrations can be stored as recipe artifacts and applied to other projects as needed. Reuse reduces the effort required for further migrations. This session covers the key concepts of DataTables, imperative Java recipes, recipe artifacts, and JavaTemplates for comprehensive migration engineering with OpenRewrite. After the session, participants will be able to apply the key constructs for planning, defining, and executing project-specific migrations.
