Modernisation assessment
A review of your codebase, dependencies and hosting with a step-by-step upgrade plan.
Legacy .NET modernisation, without stopping the business
Older .NET Framework, Web Forms and WCF applications still run many businesses, but they get harder to host, secure and change every year. We move them to modern .NET and the cloud in safe, incremental steps.
Legacy .NET Modernisation
What is included
.NET Framework to .NET 10
Migrate libraries, services and web applications to current, supported .NET.
Web Forms and MVC upgrades
Move user interfaces to ASP.NET Core, Blazor or a modern JavaScript front end.
WCF and SOAP replacement
Replace legacy services with REST or gRPC APIs while keeping clients working.
Database modernisation
Clean up schemas, move to Entity Framework and upgrade database versions.
Cloud migration
Move from on-premises servers to Azure with automated deployments.
Track record
Experience behind this service
Delivered by our lead engineer in previous roles, for FinTech, SaaS and charity organisations.
- 5+ MVC applications moved to BlazorLed the migration of legacy ASP.NET MVC applications to Blazor, cutting maintenance overhead.
- .NET Core 3.1 to .NET 6Led upgrades of enterprise platforms to a supported, long-term .NET release.
- Monoliths split into microservicesBroke large monolithic platforms into services that scale and deploy independently.
- Legacy front ends to modern SPAsMoved older applications to React and Angular single-page front ends.

Signs you need legacy .NET modernisation
- Your application runs on .NET Framework 4.x or older
- Hosting depends on an ageing Windows server that is difficult to maintain
- Finding developers for the technology is getting harder
- Security or compliance reviews flag unsupported components

FAQ
Questions about legacy .NET modernisation
Do we have to rewrite everything?
Usually not. Most applications can be upgraded incrementally, retaining the business logic and replacing only the components that block the upgrade.
Will there be downtime?
The aim is to avoid downtime entirely, or keep it to a minimum. Old and new parts run side by side and traffic is moved over in stages.
How long does a migration take?
It depends on size. The assessment gives a phased plan with an estimate for each phase before any migration work starts.
