This post describes AWS Transform custom, an agentic-AI service that automates large-scale Java application modernization with AWS-managed and user-defined transformations. It demonstrates migrating a Gradle Spring Boot Movie Service from Java 8 to Java 21 using the ATX CLI, configuration files, and interactive or direct execution modes. The article outlines transformation planning, validation steps, and Git workflow integration for repeatable upgrades.
Key Points
- 1Provides AWS-managed and user-defined transformations, using agentic AI for automated Java upgrades (Java 8 to 21)
- 2Reduces manual refactoring time and error-prone work by delivering repeatable, vetted transformation plans at scale
- 3Integrates via ATX CLI into workflows and CI/CD, enabling automated validation and large-scale code modernization
Scoring Rationale
Official AWS tooling provides high actionability and enterprise scope, while the approach offers limited methodological novelty beyond automation.
