Application Modernisation
We modernise legacy applications and platforms to reduce technical debt, improve performance and maintainability, and create a stronger foundation for cloud, integration, and future innovation.
The Challenge
What legacy systems cost you
01
Legacy systems slowing delivery and innovation
Older platforms and tightly coupled architectures can make change slower, more complex,
and more expensive—limiting the ability to respond quickly to business needs.
02
High maintenance costs
and technical debt
Accumulated technical debt, duplicated logic, outdated components, and workaround-heavy solutions can increase support effort and consume capacity that could otherwise be used for new development.
03
Limited scalability and performance constraints
Legacy architectures and infrastructure can struggle to support growing transaction volumes,
user demand, and evolving performance requirements.
04
Difficulty integrating with modern platforms and technologies
Older applications may lack the APIs, interfaces, and architectural flexibility needed to integrate effectively with cloud services, modern applications, data platforms, and automation capabilities.
05
Legacy technology becoming harder and riskier to support
Ageing or unsupported technologies can increase operational risk, security exposure,
compatibility issues, and dependency on increasingly scarce skills.​
Our Approach
Five steps, in order
1
Assess
Assess before we modernise
Understand the current application landscape, technical debt, dependencies, business constraints, and modernisation priorities before selecting the right path forward.
2
Architect
Architecture-led modernisation
Define a target architecture appropriate to the system and business need, using modular, API-first, cloud-native, or distributed patterns where they add value.
3
Transform
Incremental transformation
Understand the current application landscape, technical debt, dependencies, business constraints, and modernisation priorities before selecting the right path forward.
4
Enable
Platform and engineering enablement
Modernise the supporting engineering environment through cloud platforms, automation, CI/CD, observability, containers,
and modern development practices.
5
Accelerate
AI-assisted modernisation
Use AI-enabled engineering practices to speed up code analysis, refactoring, testing, documentation, and migration — while maintaining architectural oversight, security, and human review.
Outcomes
What changes once it's modernised
1.
Improved business value and adaptability
Modernised platforms are easier to evolve, so you can respond faster to changing priorities, customer needs, and new opportunities.
2.
Reduced technical debt and support overhead
Simplified architectures, updated technologies, and cleaner codebases free engineering capacity for higher-value work.
3.
Faster, more consistent delivery
4.
Stronger performance, scalability, and resilience
Modern engineering practices, automation, and improved
development environments help teams ship changes more quickly and reliably.
Modern architectures and platforms give growing workloads a firmer foundation, with better availability and headroom.
5.
Better integration and platform readiness
Modernised applications are better positioned to connect to cloud services, APIs, data platforms, automation, and AI capabilities.
6.
Governance and best-practice alignment
Modernisation is aligned to architecture standards, security requirements, and cloud platform guidance, for sustainable long-term operation.
Choosing the Right Modernisation Path
Modernisation is not a one-size-fits-all exercise. We assess each application based on business value, technical condition, risk, dependencies, cost, and strategic importance to determine the most appropriate path forward.
Least disruption
Retain
No change
Most transformation
Keep applications that continue to meet business and technical needs effectively.
Retire
Decommission
Decommission applications once their functionality has been consolidated or is no longer needed.
Rehost
Lift and shift
Move applications to a new hosting environment with minimal changes.
Replatform
Targeted change
Move applications to a more modern platform while making targeted improvements.
Refactor
Restructure
Restructure selected parts of the application to improve maintainability, scalability, and use of modern capabilities.
Rebuild
Re-engineer
Redesign and re-engineer applications where the existing solution has significant structural limitations.
Replace
Adopt new
Adopt a commercial, SaaS, or alternative platform where it provides greater value
than the existing solution.
