Modernise legacy applications without stopping the business
Assess, stabilise and incrementally rebuild ageing systems while they keep running.
Legacy systems often hold years of business logic but become hard to secure, change and host. Big-bang rewrites are risky. We assess the current system, stabilise critical areas and modernise incrementally — replacing components one at a time.
The result is a maintainable codebase on supported technology, with knowledge captured in documentation and tests.
Benefits
Lower risk
Incremental replacement instead of a risky rewrite.
Improved security
Supported frameworks and patched dependencies.
Easier to change
Tests and documentation make future work faster.
Reduced hosting cost
Modern platforms run efficiently on current infrastructure.
Typical use cases
- .NET Framework and WebForms upgrades
- Old PHP applications
- Desktop to web migration
- Unsupported database upgrades
Our process
Discovery & scoping
Workshops to understand your goals, users, constraints and success measures. You receive a written scope, estimate and delivery plan.
Design & architecture
User flows, wireframes and technical architecture are agreed before build starts, so cost and risk are visible early.
Iterative development
Two-week sprints with working demos, a shared backlog and transparent progress reporting.
Testing & hardening
Automated and manual testing, security checks and performance tuning before every release.
Launch & support
Planned deployment, monitoring, handover documentation and an optional support plan.
What you receive
- Legacy system assessment
- Modernisation roadmap
- Automated tests around critical logic
- Incremental migration releases
- Updated documentation
Frequently asked questions
Do we have to rewrite everything?
No. We usually keep what works and replace components in stages.
What if there is no documentation?
We reverse-engineer key workflows and document them as part of the assessment.
Can the system stay online during modernisation?
Yes. Incremental releases are designed to keep the business running.
