Legacy application modernisation
Stop legacy systems holding your business back
Relying on legacy systems can significantly inhibit your business growth. We transform outdated applications into modern, scalable cloud-native platforms, reducing cost, improving performance, and unlocking new capabilities.
Is your legacy system holding your business back?
Data security, management, and threats of breach are real concerns, equating to millions in lost revenue
Teams continue to work with slow, outdated, disparate systems
Quick fixes only provide a temporary solution
Vendor support contracts for legacy platforms are increasingly expensive
Difficulty integrating modern tools and technologies into ageing architecture
Talented developers refuse to work with outdated tech stacks
What modernisation unlocks for your organisation
Reduce risk and technical debt
Legacy systems are a security liability: outdated dependencies, missing patches, and brittle code create real exposure. Modernisation eliminates these vulnerabilities and brings your stack up to enterprise-grade standards.
Unlock scalability and performance
Cloud-native architecture means your application scales with demand rather than struggling under it. Eliminate the slow response times and downtime that come with ageing infrastructure.
Reduce licensing and maintenance costs
Stop paying for expensive legacy vendor support contracts and one-size-fits-all SaaS licences. A modernised, owned application frees your budget for growth rather than maintenance.
Enable faster innovation
Modern architectures (microservices, APIs, cloud-native deployments) give your teams the agility to iterate quickly and integrate new capabilities, from AI to IoT, without a full rebuild each time.
Choosing the right modernisation strategy
Not every legacy system needs the same approach. We help you choose between rearchitecting, refactoring, replatforming, or replacing, always based on your business objectives, budget, and timeline.
Rearchitect
Redesign the application from the ground up using cloud-native patterns. The highest investment, but delivers the greatest long-term flexibility and performance gains.
Refactor
Restructure existing code to improve quality, reduce complexity, and prepare it for cloud deployment, without changing its external behaviour.
Replatform
Lift and optimise: migrate to a modern cloud platform with targeted changes to take advantage of cloud capabilities, without a full rewrite.
Replace
When a legacy system is beyond economical repair, we help you select, configure, or build a modern replacement that meets your exact requirements.
Our 4-step modernisation process
Every modernisation is different. We tailor each stage to your system, your risk tolerance, and your business goals.
Application Assessment & Discovery
We start with a thorough assessment of your current systems, reviewing architecture, code quality, security posture, and integration dependencies. You'll receive a clear picture of your modernisation options, recommended strategy, and a realistic estimate of effort and cost.
Design & Architecture
Our Solutions Architect designs the target-state architecture, selecting the right cloud-native patterns, services, and migration approach for your context. We align on a phased delivery plan that minimises disruption to your live systems throughout.
Build & Migrate
We execute the modernisation in agile sprints, rebuilding, refactoring, or replatforming your application incrementally. Data integrity is validated at every stage. Regular demos keep you in the loop and give you confidence in what's being delivered.
Go Live & Handover
After user acceptance testing, security reviews, and a successful Go/No-Go, we manage the transition to production. You receive 30 days of free post-launch care and full access to source code, infrastructure, and documentation, so you're never locked in.
Your extended team of experts
Our permanent, onshore team takes the time to understand your company's goals, customers, and tech requirements. Here's who will help bring your vision to life.
Solutions Architect
Assesses your current systems, designs the target-state architecture, and oversees technical governance throughout delivery.
Business Analyst
Translates your high-level goals into detailed technical and functional requirements for the modernised system.
Delivery Manager
Your main point of contact. Plans and manages resources across the programme, keeping delivery on time and on budget.
QA Analyst
Oversees all testing (functional, performance, and security), ensuring the modernised application meets the agreed standards before go-live.
Backend Engineer
Leads the core rebuild or migration work, implementing new cloud-native services and APIs while preserving critical business logic.
Frontend Engineer
Modernises the user-facing layer, improving performance, accessibility, and user experience as part of the overall transformation.
Frequently asked questions
How do I know which modernisation strategy is right for me?
It depends on the condition of your current codebase, your budget, and your timeline. Our Application Assessment gives you a clear recommendation based on an objective review of your systems. The options range from a targeted refactor through to a full rearchitect or replacement.
Will modernisation disrupt our live operations?
We design our migration approach specifically to minimise disruption. Delivery is phased so that your current system remains live throughout, and we use blue/green deployment strategies and rigorous testing to ensure a smooth cutover when the time comes.
Do we get ownership of the new code?
Yes, full source code, infrastructure scripts, and documentation are handed over to you at the end of the project. You are never locked in to Talk Think Do for ongoing access to your own systems.
How long does a modernisation project take?
It depends on the scope and chosen strategy. A targeted refactor of a single application might take 3–4 months. A full rearchitect of a complex enterprise system could take 12–18 months. The Discovery phase will give you a precise estimate.
Can you support us after go-live?
Yes, all projects include 30 days of free post-launch care. Beyond that, our Managed Application Support service provides ongoing monitoring, maintenance, and continuous improvement under a flexible SLA arrangement.
