Solution Modernisation

The Problem

Legacy Systems Are Expensive

That application you built years ago? It still works. Mostly. But every change takes longer than it should. The developers who built it are gone. It runs on outdated technology that's increasingly hard to support.

You're caught in a trap: too invested to start over, too constrained to grow. Every year, the technical debt compounds. Security vulnerabilities accumulate. Integration with modern tools becomes harder.

Meanwhile, your competitors are moving faster—because their systems aren't holding them back.

Sound Familiar?

Simple changes take weeks, not days
The original developers have moved on
You're running unsupported .NET Framework versions
Cloud hosting isn't an option with current architecture
Security audits keep flagging the same issues
New hires struggle to understand the codebase
Performance is degrading as data grows

The Solution

Strategic Modernisation, Not Rip-and-Replace

You don't have to start from scratch. With the right approach, we can modernise your systems incrementally—reducing risk, preserving business logic, and delivering value along the way.

.NET Migrations

Upgrade from .NET Framework to .NET 8+ for better performance, cross-platform support, and long-term maintainability.

Cloud Migration

Move from on-premise servers to Azure for scalability, reliability, and reduced infrastructure overhead.

Architecture Refactoring

Break apart monoliths, introduce proper layering, and create an architecture that supports future growth.

Database Optimisation

Address performance bottlenecks, clean up schema issues, and prepare your data layer for modern demands.

Security Hardening

Fix vulnerabilities, implement modern authentication, and bring your systems up to current security standards.

UI/UX Refresh

Modernise the user experience without rebuilding the entire application. New frontend, preserved backend.

Common Migration Paths

Where Are You Starting From?

Every modernisation journey is different. Here are some of the common paths we help clients navigate.

.NET Framework → .NET 8+

Microsoft's .NET Framework is in maintenance mode—no new features, limited support horizon. Modern .NET offers dramatic performance improvements, cross-platform deployment, and active development.

Typical timeline: 2-6 months depending on complexity

On-Premise → Azure Cloud

Stop managing servers. Azure provides scalable, secure infrastructure with pay-as-you-go pricing. We handle the migration, including data, applications, and integrations.

Typical timeline: 1-4 months depending on infrastructure

Monolith → Modular Architecture

Tightly coupled systems are hard to change and risky to deploy. We incrementally decompose monoliths into well-defined modules or services that can evolve independently.

Typical timeline: 3-12 months (done incrementally)

Web Forms → Modern Frontend

Legacy ASP.NET Web Forms applications are difficult to maintain and offer poor user experiences. We can migrate to Blazor, React, or other modern frameworks while preserving your business logic.

Typical timeline: 2-8 months depending on size

How We Work

Modernisation Without the Risk

Rip-and-replace is risky and expensive. We take an incremental approach that delivers value continuously while minimising disruption.

1

Assessment & Discovery

We analyse your existing system—codebase, architecture, dependencies, and pain points. You get a clear picture of what you have and a roadmap for where to go.

2

Prioritised Roadmap

Not everything needs to change at once. We identify quick wins, critical fixes, and strategic improvements—then sequence them for maximum value with minimum risk.

3

Incremental Delivery

We modernise in phases, delivering working improvements every few weeks. You see progress, provide feedback, and can adjust priorities as we learn.

4

Parallel Running

For critical systems, we run old and new in parallel until you're confident. No big-bang cutovers, no crossed fingers.

Our Modernisation Principles

🎯 Preserve business logic
Your processes are encoded in that legacy system. We extract and preserve what matters.
📈 Deliver value continuously
No waiting months for a "big reveal." You see improvements every sprint.
🔄 Enable rollback
Every change is reversible. If something goes wrong, we can recover quickly.
📚 Transfer knowledge
We document everything and train your team. No new "black box" to replace the old one.
🛡️ Reduce risk first
Security vulnerabilities and stability issues get priority before feature work.

The Big Question

Modernise or Rebuild?

It's the question every legacy system owner faces. Here's how we think about it.

Modernise When...

Core business logic is sound and valuable
The system mostly does what you need
Budget or timeline doesn't allow full rebuild
Gradual improvement is acceptable
Technical issues are fixable, not fundamental
You need to maintain continuity during transition

Rebuild When...

Requirements have fundamentally changed
The architecture is beyond rescue
Modernisation would cost more than rebuilding
You're changing the entire business model
Technical debt is so deep it's unmaintainable
You have runway for parallel development

Not sure which applies to you? That's exactly what our assessment is for. We'll give you an honest recommendation—even if it means telling you to rebuild, or that the current system is actually fine.

Investment

Modernisation Pricing

Every legacy system is different, so we scope each engagement individually. Here's how we typically structure modernisation projects.

Initial Assessment

Fixed Price

1-2 week deep dive into your codebase. You get a full assessment report and modernisation roadmap—yours to keep regardless of next steps.

Modernisation Phases

T&M or Fixed

Each phase is scoped and priced individually. You can proceed phase-by-phase, adjusting based on results and priorities.

Ongoing Support

Retainer

After modernisation, transition to one of our maintenance tiers for continued support and evolution.
