Legacy assessment
Analysis of code, architecture and dependencies that shows the risks, the technical debt and the most valuable modernisation path.
Application modernisation without stopping the business
We refactor and re-platform legacy systems step by step, moving monoliths, outdated frameworks and on-premises databases to modern, cloud-ready architectures while your business keeps running.
What we do
Scope of work
Incremental migration
The strangler fig approach: new modules replace old ones one by one behind a stable interface, with no big-bang cut-over.
Framework and runtime upgrades
Moving from .NET Framework, old Java versions, AngularJS or legacy PHP to supported, modern stacks.
Database modernisation
Migration from Oracle or legacy SQL Server to PostgreSQL or managed cloud databases, with data reconciliation.
Re-platforming to containers and cloud
Packaging applications into containers, adding CI/CD and moving them to Kubernetes or managed platform services.
