Entity Framework Migration

Use this skill when modernizing data layers from Entity Framework 6 or older patterns to EF Core.

When to use

• Assessing EF6-to-EF Core migration feasibility
• Refactoring data access patterns and DbContext configuration
• Migrating model mappings and conventions
• Planning phased cutovers for schema and query behavior changes

Inputs

• Existing data access projects and context classes
• Current migration history and database schema constraints
• Query hot paths and performance baselines

Outputs

• EF migration approach and risk summary
• Mapping and query refactor checklist
• Validation strategy for correctness and performance
