Legacy .NET Modernisation

Legacy .NET
Modernisation

Whether your .NET Framework 1.1–4.8 system needs rescuing, migrating to .NET 8 or 10, or you want to build something brand new on modern .NET — we have the team and the depth. Legacy is our speciality. Modern .NET is our everyday.

The Problem

Why Legacy .NET Systems
Can't Stay as They Are

Every year on an unsupported framework is a year of compounding risk — security vulnerabilities, rising maintenance cost, and a shrinking pool of developers who understand the code.

Security Vulnerabilities Accumulating

Older .NET Framework versions no longer receive security patches. Every month of delay is another month of unpatched CVEs in production.

Can't Integrate with Modern Tools

Legacy .NET apps struggle to connect to modern APIs, cloud services, mobile apps, and BI platforms — leaving the business operating in silos.

Developers Can't Be Found

The pool of developers who understand VB.NET, WebForms, WCF, and COM interop shrinks every year. Support becomes expensive and fragile.

Technical Debt Compounding

Every hotfix and workaround added over the years makes the next change harder and more dangerous. The cost of the next bug fix keeps rising.

Our Approach

Phased Migration,
Not a Rewrite

We never do a big-bang rewrite. We migrate your system incrementally — module by module, layer by layer — so your business keeps running throughout the entire process. Each phase is tested, documented, and signed off before the next begins.

The business logic in your legacy system is the product of 20 years of real-world decisions. Our job is to carry it forward — not recreate it from scratch.

What We Modernise

The Full Migration Spectrum,
Framework to .NET 10

From VB.NET 2003 to C# on .NET 10 — we handle every era of .NET modernisation with surgical precision.

Codebase Assessment & Risk Mapping

Full audit of your existing architecture, dependencies, third-party integrations, and breaking-change risk before any migration begins.

.NET Framework → .NET 8 / 10 Migration

Incremental migration of your application from .NET Framework 1.1–4.8 to modern .NET — preserving business logic, step by step.

WebForms → Blazor / Razor Pages

Modernise ageing ASP.NET WebForms UIs to Blazor Server, Blazor WASM, or Razor Pages without discarding the underlying business logic.

WCF & ASMX → REST / gRPC APIs

Replace legacy SOAP and WCF services with modern .NET Web API endpoints — maintaining compatibility with existing consumers during transition.

Database Modernisation

Upgrade from SQL Server 2005/2008 schemas and raw ADO.NET to modern EF Core patterns, with performance tuning included.

DevOps & CI/CD Setup

Introduce modern deployment pipelines, Azure DevOps or GitHub Actions, containerisation, and environment management for the modernised system.

How We Modernise

Our Phased Modernisation
Engagement Model

No big-bang rewrites. Every migration is structured in controlled phases, with your system running throughout.

01

Codebase Audit & Dependency Mapping

We document every layer — framework version, NuGet packages, COM dependencies, third-party APIs, and deployment process.

02

Migration Roadmap & Phase Planning

We design a phased upgrade plan — breaking the migration into safe, testable increments with clear milestones and rollback points.

03

Incremental Migration & Testing

We migrate module by module. Each phase is fully tested against your existing business rules before the next begins.

04

Handover, Documentation & Support

Full technical documentation, team knowledge transfer, and ongoing support once your modernised system is live on .NET 8 or 10.
