Application modernisation
Move off legacy without stopping the business.
We migrate desktop and ageing .NET applications to modern web architectures step by step, with automated tests guarding behaviour at every stage.
Signs you need this
- A critical desktop application runs on a few machines and only a few people understand it.
- Every change to the legacy code base breaks something unrelated.
- The database schema has grown for a decade without a design.
- The rewrite keeps being postponed because the risk looks too high.
What we do
Code base assessment
Static analysis with tools such as NDepend to map dependencies and hotspots, followed by a technical roadmap.
Target architecture
SOLID layering, repository and unit-of-work patterns and dependency injection, sized to the application instead of copied from a template.
Incremental migration
Features moved module by module, with old and new systems running side by side where needed.
Safety net
Acceptance tests in SpecFlow and Selenium written against today’s behaviour before anything changes.
Data redesign
Database redesign, datamart modelling and SSIS flows.
What you get
- An assessment and a migration roadmap
- An automated acceptance test suite
- Migrated modules in production
- A CI/CD pipeline

Should we rewrite from scratch?
Rarely. An incremental migration keeps delivering value and exposes surprises early. We recommend a rewrite only when the assessment shows the existing code cannot carry the target design.
Can the migration happen while the team keeps shipping features?
Yes. That is the point of migrating module by module, with tests guarding behaviour.
