Is rebuilding faster than refactoring?

Sometimes, but only when the old system is too coupled or unsafe to evolve. Refactoring is usually faster when behavior is clear and tests can be added incrementally.

What should be modernized first?

Start with a workflow that has measurable business value, visible risk, manageable dependencies, and enough test coverage to verify the replacement without breaking lead, billing, reporting, auth, support, or admin paths.

How do you modernize without stopping the business?

Use migration slices, compatibility APIs, feature flags, parallel reporting, smoke tests, rollback rehearsals, and owner sign-off so the old path can stay available until the new path is proven.
