When should a company rebuild instead of refactor?

A rebuild is more appropriate when the existing architecture blocks core business goals, cannot be secured reasonably, or makes every change slower than building a controlled replacement path.

How do you modernize without disrupting operations?

Use parallel slices, compatibility layers, audit checkpoints, data reconciliation, and staged releases so teams can validate behavior before switching critical workflows.
