FAQPage Schema
How do I migrate an EF6 application to EF Core?▼

To migrate an EF6 application to EF Core, you should separate runtime upgrades from ORM upgrades and use a decision framework to validate migration slices. This approach ensures a smooth transition by addressing legacy data access patterns incrementally rather than rewriting everything at once.

What is the best way to maintain a legacy Entity Framework 6 codebase?▼

Maintaining a legacy Entity Framework 6 codebase involves applying best practices to keep applications stable and performant. You should review existing EDMX or code-first patterns and seek realistic maintenance advice to manage technical debt without forcing an immediate framework upgrade.

Should I upgrade the .NET runtime or refactor to EF Core first?▼

You should separate runtime upgrades from ORM upgrades when modernizing EF6. Upgrading the .NET runtime first provides immediate benefits while allowing you to use a structured decision tree to plan your Entity Framework Core migration independently.

How do I handle EDMX legacy data access patterns when moving to modern .NET?▼

Handling EDMX legacy data access patterns during a modern .NET move requires reviewing the existing models and applying validated migration slices. This process ensures you can safely transition away from visual designers without breaking core data access logic.

Does this EF6 guidance work for both code-first and EDMX approaches?▼

Yes, this EF6 guidance covers scenarios involving both code-first and EDMX approaches. It provides specific reviews and maintenance advice tailored to your application's existing data access patterns to ensure confident modernization.
