Concepts
GitHub Copilot App Modernization for Java (preview) is a tool covering application migration to Azure end to end, from application assessment, planning, code remediation and build fix. It aims to help you migrate to and run your applications on Azure with confidence and accelerate the whole cycle, powered by the artificial intelligence of GitHub Copilot.
GitHub Copilot App Modernization for Java (preview) uses Azure Migrate application and code assessment (AppCAT) to discover and assess your code. This tool is a good starting point in your App Modernization journey. For more information, see Azure Migrate application and code assessment for Java version 7 (preview).
You can invoke GitHub Copilot App Modernization for Java (preview) to get an overview of cloud readiness migration issues, including the following recommendations:
- Instructions for setting up Azure resources.
- Recommendations on following best practices.
- Recommendations on changing your application code.
In scenarios where code changes are required, App Modernization for Java (preview) guides you on the code remediation step. At this stage, you can use predefined formulas for common issues, such as the following issues:
- Switching from password-based authentication to managed identities.
- Moving from Amazon Web Services (AWS) S3 to Azure Blob Storage.
To learn more about predefined formulas available in the App Modernization for Java (preview) today, see Predefined formulas.
When it comes to development, enterprises often have strict processes and controls. This area is where customer-defined formulas come in.
Customer-defined formulas are generated by analyzing code commits from an already-migrated application. These formulas guide Copilot to remediate code in another app based on the same pattern. This process enables rapid remediation across multiple applications. Each successful migration grows the knowledge base and reduces effort for the next one.
Finally, App Modernization for Java (preview) includes a Build Fix agent designed to help with build-related errors. Because AI-based suggestions can sometimes miss a parameter or change a method incorrectly, the Build Fix agent intervenes to provide support and correction.
