Case Study: How AI Accelerated Application Modernization

This case study reveals the journey of transforming an 8-year-old Spring Boot application with Groovy, YAML and Angular into a modern Java 21, Spring Boot 3.4, and Vaadin solution. We'll share how AI dramatically accelerated this process, reducing weeks of refactoring to mere hours.

The presentation explores both technical and strategic decisions, including the migration from Gradle to Maven, implementation of security features, cross-platform deployment, and construction of a maintainable architecture designed for future microservices migration.

We'll demonstrate how AI transformed challenging tasks like Groovy-to-Java conversion and test migration from Spock to JUnit 5. You'll also hear the marketing perspective on UI/UX modernization and WordPress implementation to accelerate market entry.

This case study offers insights for developers considering application modernization, highlighting successful approaches and mistakes made along the way. Discover how AI can dramatically reduce modernization time while improving code quality and maintainability.
