Overview

Devin can take away the pain of migrations, helping you move between different frameworks, languages, etc. Use playbooks to easily reuse prompts for large migrations.

​
Use Cases

  2. Framework upgrades (e.g., React 17 to 18)
  3. Database migrations
  4. Dependency updates
  5. Architecture modernization

​
Example Prompts

Java upgrade
## Overview
This playbook provides step-by-step instructions for upgrading a Java 7 project to Java 8.

## Procedure
1. Verify if the provided project is indeed on Java 7
2. Install Java 8 Development Kit (JDK)
3. Update the project's build configuration
4. Identify and replace deprecated Java 7 APIs
5. Analyze the codebase for potential Java 8 enhancements
6. Update unit tests
7. Perform thorough testing
8. Update documentation
9. Build and verify the application

## Advice and Tips
- Refer to the Java 8 documentation for detailed information on new features and APIs
- For large-scale migrations, consider using the [API Reference](/api-reference/overview) to run multiple migration sessions in parallel
TypeScript migration
Please help migrate our JavaScript project to TypeScript. We need to:
1. Add TypeScript configuration
2. Convert .js files to .ts
3. Add appropriate type definitions
4. Update build process
5. Ensure all tests still pass
