Legacy systems create security vulnerabilities, drain budgets with high maintenance costs, and make integration nearly impossible. This service is perfect for organisations relying on outdated or monolithic applications that need to perform efficiently.
Refactored legacy code and improved architecture that results in higher code quality and easier long-term maintenance.
Improved performance & scalability
Optimised performance, faster response times, and cloud-ready architecture delivered through legacy software modernisation services that scale with demand.
Stronger security & compliance
Enhanced data protection, improved compliance readiness, and secure cloud or mainframe modernisation to reduce operational and regulatory risk.
Better customer experience
Improved usability and accessibility across modern digital interfaces enabled by legacy application modernisation.
Business agility & AI readiness
Adoption of modern technologies that support AI integration and business-critical systems.
Our Legacy Software Modernisation Approach Across the 6Rs
Rationalise
We assess legacy systems as part of our legacy software modernisation services, define a clear roadmap, and decide what to replace, rebuild, or retire.
Refactor
We improve existing code through legacy application modernisation to reduce technical debt while maintaining stability.
Replatform
We move applications to modern or cloud platforms, including mainframe modernisation, with minimal disruption.
Rearchitect
We redesign systems using API-first and event-driven architectures to support long-term modernisation.
Re-engineer
We modernise business-critical systems while preserving data integrity and operational continuity.
Reimagine
We refresh user experience with accessible, user-centred UX UI modernisation.
Our Legacy Software Modernisation Process
01
Discovery & proof of concept
We validate the approach early through a focused proof of concept to reduce risk in legacy application modernisation.
02
Risk assessment & mitigation
We identify technical and business risks upfront and define controls to support safe legacy software modernisation services.
03
Phased migration
We migrate systems in stages to minimise disruption, including complex mainframe modernisation efforts.
04
Testing & validation
We test functionality, performance, and security to ensure stability throughout the modernisation process.
05
Legacy software migration
When you need your technology to move in sync with your business goals.We complete the migration to modern platforms while preserving data integrity and business continuity.
Legacy Modernisation Deliverables
Modernisation roadmap
A structured roadmap based on legacy system assessment and technical analysis. We define scope, risks and priorities to guide successful legacy application modernisation.
Modernised applications
Refactored or rebuilt applications using modern frameworks. We reduce technical debt, improve performance, and strengthen long-term maintainability.
Cloud & infrastructure setup
Secure cloud migration and infrastructure configuration aligned with your target architecture, enabling scalability and resilience.
Modern DevOps pipeline
CI/CD automation, integrated testing and streamlined release processes to accelerate delivery and improve reliability.
Documentation & knowledge transfer
Clear support documentation, runbooks, playbooks and system architecture diagrams to ensure smooth handover and internal capability building.
API & integration layer
REST APIs are designed with an API-first approach and supported by secure API gateways to enable seamless system integration.
What are the main approaches to modernising legacy systems?
Common approaches include rehosting, refactoring, replatforming, and full re-architecture. Legacy software modernisation services may also involve partial replacement or integration with modern platforms. The right approach depends on business goals, technical constraints, and the need for future scalability or cloud adoption.
How much does legacy system modernisation cost?
The cost of legacy application modernisation varies based on system size, architecture, integrations, and security or compliance requirements. Mainframe modernisation typically requires a higher investment due to complexity, but it often delivers long-term cost savings through improved performance, reduced maintenance, and better scalability.
How long does a legacy software modernisation project take?
The timeline for legacy software modernisation services depends on system complexity, technology stack, and business criticality. Smaller legacy application modernisation projects may take a few months, while large-scale systems or mainframe modernisation can take longer. A phased approach is often used to reduce risk and ensure business continuity.
