Amazon Q Code Transformation is a new feature that automates Java application upgrades using generative AI. The presenters demonstrate how this tool can significantly reduce the time and effort required for upgrading legacy applications from Java 8 or 11 to Java 17. By leveraging knowledge bases, LLMs, and automated build processes, Q Code Transformation can perform upgrades in minutes that would typically take developers days or weeks. The tool analyzes code, applies necessary changes, fixes errors, and provides developers with a fully upgraded codebase ready for review and deployment. This automation helps teams balance maintaining up-to-date, secure applications with focusing on new feature development. The presenters also discuss future plans to expand the tool's capabilities to other languages and frameworks.
