Legacy Application Modernization
Moving aging applications forward incrementally — because the big-bang rewrite is how these projects usually fail.
The problem
The application still works. That's exactly the problem: it runs the business, the framework hit end of support years ago, the one person who understood it has left, and every change is now a small act of archaeology.
The instinct is to rewrite it from scratch. That's the approach with the worst track record in our industry — an eighteen-month project to reach feature parity with something that already worked, while the old system keeps accruing changes you have to catch up on.
What's included
- Assessment of the existing codebase, dependencies, and support status
- Incremental migration strategy — strangler-fig rather than big-bang rewrite
- Framework upgrades (.NET Framework to modern .NET, AngularJS to Angular)
- Database modernization and data migration
- Extracting business logic that only exists inside forms and stored procedures
- Adding automated tests around behavior before changing it
- Re-platforming to cloud or private cloud hosting
- Documentation of the system as it actually behaves, not as originally specified
How we deliver
Discover, prototype, build, support
Discover
A paid, fixed-fee engagement producing requirements and a real estimate. You own the output.
Prototype
Clickable screens before code. Changing a wireframe takes an hour; changing a built screen takes days.
Build
Short increments with something demonstrable at the end of each. No six-month silence.
Support
Source code, documentation, and infrastructure handed over. Ongoing support optional, never required.
Modernization: common questions
Should we rewrite or modernize incrementally?
Incrementally, in most cases. Replacing pieces behind a stable interface while the system keeps running means you get value early and can stop if priorities change. Full rewrites are defensible when the platform is genuinely dead or the domain has changed so much that feature parity isn't the goal.
The original developer is gone and there's no documentation. Is that a problem?
It's the normal starting condition. We work from the code and the database, and we write down what the system actually does. That documentation is often worth the engagement on its own, independent of any modernization.
Can this happen while people keep using the application?
Yes, and it should. Incremental migration means the old and new run side by side with traffic gradually shifting. Users typically notice improvements before they notice a migration is happening at all.
