rewrite

To rewrite a legacy application, you must first inventory all business logic and cross-cutting concerns, then map them to a target architecture. This structured workflow minimizes risk and ensures functional equivalence throughout the migration.

The best way to plan a legacy system migration is by applying end-to-end rewrite scoping and governance. This approach maps business rules to scaffolding artifacts and provides formal risk mitigation steps to safely rebuild the application.

Yes, rewriting legacy software requires a complete inventory of business rules and cross-cutting concerns mapping before scaffolding begins. This ensures the modern target stack correctly preserves functional outcomes and reduces technical debt.

You verify functional equivalence after migrating legacy code by applying formal verification and validation phases. This ensures the newly scaffolded target architecture matches the original business rules and outcomes without regressions.

A complete application rewrite is suitable when you need to reduce significant technical debt and rebuild apps clearly. It supports varying project scopes and governance requirements where incremental updates cannot safely preserve business outcomes.

To map cross-cutting concerns during a legacy software rewrite, you extract them into the initial business logic inventory. This data is then mapped directly to scaffolding artifacts in the target architecture to maintain functional equivalence.
