Developed a targeted migration rule for the Azure/appcat-konveyor-rulesets repository, addressing the transition from enum to class for the HttpMethod component in Spring Framework 6.0. The work focused on automating migration guidance, reducing manual intervention for developers updating their codebases. Leveraging Java and YAML, the rule was implemented using code analysis techniques and the Konveyor rulesets DSL to ensure accurate detection and transformation of affected code. This contribution enhanced migration readiness and consistency across projects adopting Spring 6.0, demonstrating proficiency in migration tooling, repository management, and the application of AST-like reasoning to real-world Java code migration challenges.
