This document provides a comprehensive assessment for migrating the Spring Boot RealWorld application from Java 11 to Java 21, including: - Dependency compatibility analysis (Spring Boot, MyBatis, DGS, JWT) - Codebase audit identifying javax.* to jakarta.* migration needs - Risk assessment for high-risk components (Security, DGS, validation) - Migration strategy recommendation (Modern approach with Spring Boot 3.2.x) The assessment recommends the Modern Approach (Spring Boot 3.2.x + Java 21) as the best long-term investment, with an estimated effort of 5-7 days.
