To migrate javax imports to jakarta for Spring Boot 3, replace javax.persistence, javax.validation, and javax.servlet packages with their jakarta equivalents and verify no javax references remain. This targets broad codebase migrations across persistence, validation, and servlet APIs.

The javax to jakarta namespace migration updates Java EE package imports to the jakarta.* namespace, enabling legacy applications to run on Spring Boot 3.x. It covers updating annotations and entity mappings for persistence, validation, and servlet domains.

Yes, you can use OpenRewrite for batch javax to jakarta code refactoring. The migration process includes batch replacement steps and OpenRewrite guidance to systematically update javax imports to jakarta across the entire codebase.

Jakarta namespace migration supports broad codebase updates across persistence, validation, servlet, annotations, and transactions domains. It enforces verification steps to confirm no remaining javax imports and that jakarta imports are properly present.

You need to refactor javax to jakarta imports because Spring Boot 3.x requires the Jakarta EE namespace instead of Java EE. Migrating these packages ensures your updated legacy services run correctly on the new framework version.
