Legacy Modernization Without Rebuilding Everything at Once

Who this is for

Is this you?

• Critical software depends on code few people now understand
• Your framework, runtime or dependencies are falling out of support
• New business requirements are difficult to add safely
• A full rewrite feels too expensive or disruptive to justify

Problems it removes

What this fixes.

• Small changes creating unexpected problems elsewhere
• Unsupported technology increasing maintenance and security risk
• Business rules hidden inside undocumented legacy code
• Limited test coverage making releases difficult to verify
• Old architecture blocking integrations, cloud moves or new features

How we approach it

The order we do things in.

1. Assess the current systemUnderstand the code, dependencies, data, infrastructure and parts of the application the business cannot lose.
2. Stabilize the foundationAddress critical backups, version control, unsupported dependencies and other risks before major changes.
3. Protect important behaviorAdd tests around the workflows and business rules that must continue working.
4. Modernize in stagesUpgrade or replace one part at a time while the application remains available to the business.
5. Document the new stateRecord architecture, dependencies and operating knowledge so the system is easier to maintain after the work is complete.

Technology

What we work in for this.

We work with technologies we support in production and choose the modernization approach around the existing system rather than forcing a complete rebuild.
