Extracting infrastructure logic is best achieved by identifying the smallest framework-specific block to move into a port/adapter layer, preserving observable behavior while enforcing neutral contracts and disciplined naming across layers.

Safely migrate EF Core dependencies by introducing an inward-facing port and an adapter that encapsulates the technical dependency, applying stepwise migration with tests to ensure behavior remains completely intact.

You need port/adapter architecture for infrastructure refactoring when orchestration code tightly couples to framework-specific concerns like Http clients, messaging, or provider APIs, requiring verifiable migration steps to decouple technical dependencies.

Yes, you can use this approach to move Http client, messaging, and provider API logic by encapsulating them in a dedicated adapter behind a neutral port contract, ensuring the extraction does not alter observable behavior.

Introduce neutral contracts by defining an inward-facing port that isolates infrastructure concerns, then implement an adapter with disciplined naming conventions across layers to enforce a proper technical layer separation.

Limitations of stepwise migration include the necessity of identifying the smallest extractable block and maintaining rigorous test coverage, as skipping verifiable migration steps risks altering observable behavior during the port/adapter separation.
