Legacy System Modernisation
Reduce Technical Debt Without Stopping the Business
What we do
Legacy applications are the biggest source of operational risk in Dutch enterprises — unsupported technology stacks, single points of failure, and the one person who understands how it works. We modernise legacy systems using strangler fig, re-platform, or rebuild strategies — keeping the business running throughout.
Ideal for
Organisations running business-critical applications on end-of-life technology with high maintenance cost and mounting operational risk
Common applications
Strangler Fig Modernisation
Incrementally replace legacy functionality behind an API facade — no big-bang rewrite, business continuity preserved.
Legacy to Cloud Re-Platform
Lift legacy .NET, Java, or PHP applications to Azure App Service or AKS with minimal code changes and immediate cloud benefits.
Database Migration & Upgrade
Migrate from end-of-life SQL Server, Access, or Oracle databases to modern Azure SQL with schema modernisation.
Monolith to Microservices
Decompose a monolithic application into independently deployable microservices — improving team velocity and scaling characteristics.
UI Modernisation
Replace dated desktop or web front-ends with modern React or Next.js interfaces while retaining backend business logic.
Third-Party Dependency Removal
Eliminate vendor lock-in from deprecated components (Flash, ActiveX, Internet Explorer-only solutions) with modern equivalents.
How we work
Technical Assessment
Document the current system: architecture, dependencies, risk inventory, and modernisation effort estimate by component.
Modernisation Strategy
Select the right approach per component: retire, retain, re-host, re-platform, refactor, or rebuild.
Phased Execution
Execute the modernisation in phases, decommissioning legacy components only after successors are validated in production.
Knowledge Transfer
Document the modernised system thoroughly and train internal teams who will maintain it going forward.
