To migrate a codebase while preserving functionalities, use a Test-Driven Development pipeline that generates failing tests first, delegates code writing to specialized agents, and validates integration against original behavioral contracts.

The best way to rewrite legacy code using TDD involves orchestrating a phased pipeline: generate specifications, write failing tests, conduct adversarial reviews, and iteratively build the new codebase through delegated specialized agents.

Agent delegation prevents context overflow during a codebase rewrite by offloading reading, writing, and validation tasks to specialized agents, passing only file paths to the orchestrator to ensure zero context growth.

Yes, you can migrate a Python application to a Go framework using TDD by orchestrating a pipeline that handles specification, failing test generation, and iterative building to guarantee all original behaviors are tested and preserved.

The phases of an automated TDD migration pipeline include specification, failing test generation, adversarial review, phased planning, iterative building, and integration validation to ensure reliable codebase rewrites.

You should use an agent delegation pipeline for code migration when transitioning entire codebases between languages or frameworks and need strict TDD guarantees to ensure new code meets original behavioral contracts without context limits.
