Migrating from traditional relational databases to a cloud-native NoSQL database can feel daunting... but it doesn’t have to be. In this session, we’ll show how you can leverage GitHub Copilot and Visual Studio Code to accelerate the modernization of a Spring application using Spring Data. We will walk through a real-world scenario of transforming an existing Spring Boot application that uses a relational database into one powered by Azure Cosmos DB.

Along the way, we’ll use GitHub Copilot Instructions to guide AI-assisted refactoring, generate entity mappings, and create new repository interfaces, while relying on Copilot’s inline suggestions to catch subtle API differences.

You’ll learn practical techniques to:

• Identify and refactor data access code with minimal manual effort
• Use Copilot to generate boilerplate migration tasks and tests
• Leverage GPT-5 for reasoning through schema design and performance trade-offs
• Validate the migration end-to-end from local development to cloud deployment
  If you are a Java developer or architect looking to modernize your Spring apps for the cloud, this talk will show you how to use AI-powered tools to get there faster, with confidence.
