Rewrite From Scratch vs Incremental Rewrite

Developers should consider a rewrite when the existing codebase has become unmaintainable due to accumulated technical debt, uses obsolete technologies, or has architectural flaws that hinder scalability and new feature development meets developers should use incremental rewrite when dealing with large, critical legacy systems that cannot be easily replaced all at once due to business constraints, high risk, or resource limitations. Here's our take.

Rewrite From Scratch

Developers should consider a rewrite when the existing codebase has become unmaintainable due to accumulated technical debt, uses obsolete technologies, or has architectural flaws that hinder scalability and new feature development

Rewrite From Scratch

Nice Pick

Developers should consider a rewrite when the existing codebase has become unmaintainable due to accumulated technical debt, uses obsolete technologies, or has architectural flaws that hinder scalability and new feature development

Pros

  • +It is particularly useful for legacy systems where the original design no longer aligns with current business requirements or modern development practices, allowing for a cleaner, more efficient implementation
  • +Related to: refactoring, technical-debt-management

Cons

  • -Specific tradeoffs depend on your use case

Incremental Rewrite

Developers should use Incremental Rewrite when dealing with large, critical legacy systems that cannot be easily replaced all at once due to business constraints, high risk, or resource limitations

Pros

  • +It is particularly valuable for minimizing downtime, enabling iterative testing and feedback, and allowing teams to deliver value continuously while modernizing the codebase
  • +Related to: refactoring, legacy-system-migration

Cons

  • -Specific tradeoffs depend on your use case

The Verdict

Use Rewrite From Scratch if: You want it is particularly useful for legacy systems where the original design no longer aligns with current business requirements or modern development practices, allowing for a cleaner, more efficient implementation and can live with specific tradeoffs depend on your use case.

Use Incremental Rewrite if: You prioritize it is particularly valuable for minimizing downtime, enabling iterative testing and feedback, and allowing teams to deliver value continuously while modernizing the codebase over what Rewrite From Scratch offers.

🧊
The Bottom Line
Rewrite From Scratch wins

Developers should consider a rewrite when the existing codebase has become unmaintainable due to accumulated technical debt, uses obsolete technologies, or has architectural flaws that hinder scalability and new feature development
