Analyze, plan, and automate your Java EE → Jakarta EE migration — directly inside IntelliJ.
Migrate from Java EE 8 (javax.*) to Jakarta EE 9+ with confidence.
This plugin detects migration blockers, analyzes dependencies, and helps you refactor safely using OpenRewrite.
The transition from javax.* to jakarta.* is not a simple rename.
- Dependencies break
- Frameworks require upgrades
- Application servers must change
- Hidden references cause runtime failures
This plugin helps you identify risks early and migrate systematically.
