Legacy Software Modernisation Company UK
We migrate, refactor and rebuild ageing UK systems into modern cloud platforms — without taking your operations offline. Strangler-fig migration, cloud lift-and-shift, and monolith-to-microservices for UK businesses.
Your Legacy System Is a Business Risk, Not Just a Tech Debt
UK businesses running on legacy software face a compounding problem: the system is too risky to touch, the engineers who built it have left, the documentation is incomplete, and every new feature takes three times longer than it should. Meanwhile, cloud-native competitors are shipping in weeks.
Cyberbeak specialises in high-risk legacy modernisation — the systems that other agencies decline because the migration is complex, the data is messy, or the business cannot afford downtime. We use the strangler-fig pattern to migrate incrementally, so your UK operations continue while the new system is built beneath them.
Legacy Modernisation Services for UK Businesses
Legacy System Assessment
Technical audit of your legacy codebase, database schema, integration points and infrastructure — producing a risk-ranked modernisation roadmap with phased cost estimates before any code is written.
Strangler-Fig Migration
Incremental replacement of legacy modules with modern equivalents — new functionality deployed behind a facade, traffic migrated gradually, old code retired safely. No big-bang rewrite risk.
Cloud Migration (AWS / Azure / GCP)
Lift-and-shift from on-premise or legacy hosting to UK-region cloud infrastructure — containerisation with Docker and Kubernetes, CI/CD pipeline setup and cloud cost optimisation.
Monolith to Microservices
Decomposition of legacy monolithic applications into independently deployable services — domain boundary identification, API contract design, event-driven decoupling and gradual traffic migration.
Database Migration & Re-Engineering
Migration from legacy databases (Oracle, SQL Server, MySQL, MS Access) to modern platforms — schema redesign, data cleansing, ETL pipeline development and zero-downtime cutover strategies.
UI Modernisation
Replacing legacy desktop UIs (Delphi, WinForms, VB6, classic ASP) with modern web and mobile interfaces — without replacing the back-end business logic that still works.
