AI Modernisation services: Turn legacy systems into AI-ready platforms

Modernise core systems end-to-end by replacing outdated architectures with scalable, cloud-ready solutions. Reducing costs, speeding up delivery cycles, and creating a strong foundation for AI at scale.

A barrier to innovation

Legacy systems are no longer just expensive to run. They are becoming harder to operate, slower to change, and increasingly risky to rely on. Rising costs, end-of-life technologies like COBOL, VB6, or legacy Java, and fragmented data landscapes are holding back innovation, delaying regulatory response, and preventing AI adoption. GFT Technologies modernises your core systems end-to-end, reducing operational costs, accelerating time-to-market, and turning legacy into a foundation for resilience and AI-ready architectures.

Why the time to act is now

Most organisations don’t choose to modernise. They are forced into it.

  • Core technologies like COBOL, VB6, and legacy Java are reaching end-of-life, and critical knowledge is disappearing with shrinking talent pools

  • Regulatory frameworks such as demand real-time resilience and traceability

  • Legacy platforms limit innovation and cannot support modern digital business models, real-time analytics, open architectures, and AI-driven personalisation.

The pressure isn't coming from one direction. It's coming from all sides at once. Cost. Regulation. Talent. Technology end-of-life. And AI adoption that's impossible to unlock on a legacy foundation.

Legacy modernisation goes beyond a technical challenge. It is now a business constraint limiting growth, compliance, and competitiveness.

What has changed is how modernisation can be delivered. By embedding Generative AI across the entire modernisation process, GFT has transformed what once considered a multi-decade effort into a structured, governed programme that can be executed with control and predictability.

Our AI Modernisation services

AI Modernisation Services are built on a strong and proven methodology refined over years. We combine a structured top-down strategy with bottom-up code execution, ensuring alignment between business goals and technical precision throughout the programme. This approach is further enhanced by specialised expertise, industry knowledge, governance frameworks, and effective change management, creating a comprehensive modernisation engine.

Advisory & portfolio assessment

Know what to modernise – and how

We give you a clear, fact-based view of your landscape and define the right modernisation path.

  • Dependency and risk mapping

  • 8R strategy (rehost, refactor, rewrite, etc.)

  • Target architecture definition

  • Business case and phased roadmap

Mainframe modernisation

Reduce cost. remove risk. future-proof your core.

We modernise mission-critical environments with the right approach:

  • Rehost → fastest cost reduction

  • Refactor → improved maintainability

  • AI-powered rewrite → future-ready architecture

Delivered with controlled risk and no disruption to running operations.

Application modernisation

From legacy applications to scalable, AI-ready systems

We transform outdated applications into modern platforms built for innovation:

  • Angular / React frontends

  • Spring Boot / .NET backends

  • API-first, modular architectures

  • AI-ready documentation

Integration & middleware modernisation

From fragile batch processing to real-time, event-driven systems

We replace fragile legacy integrations with scalable, event-driven architectures:

  • Kafka and event streaming

  • Microservices and APIs

  • Standardised integration patterns

Data, analytics & AI enablement

Make AI adoption possible – and practical.

We modernise your data foundation so AI initiatives can deliver value:

  • Migration from legacy data platforms

  • Real-time data pipelines

  • AI-ready data models and governance

  • LLMOps and advanced analytics enablement

Performance optimisation & cost take-out

Cut cost without standing still.

We identify and implement high-impact improvements while your future architecture takes shape.

  • Mainframe consumption reduction

  • Batch and workload optimisation

  • Licensing cost reduction

  • Prioritised savings backlog

Faster time-to-market
100%
Functional equivalence where required

Why GFT

We modernise the systems others avoid: mission-critical platforms where failure is not an option and transformation must happen without disruption. For nearly 40 years, GFT has delivered complex transformations in the most demanding environments – at scale, with control, and without compromise.

  • AI-accelerated delivery: Wynxx Transformer Edition automates reverse engineering, code conversion, test generation, and documentation – cutting effort and time at every stage of the modernisation journey.
  • AWS. Azure. Google Cloud: We deliver on the platforms enterprises run on. GFT's partnerships with AWS, Microsoft Azure, and Google Cloud mean your modernised systems are built, validated, and optimised on the infrastructure that powers your future.
  • Deep regulated-sector expertise: We modernise banking-grade, mission-critical systems, not generic enterprise apps.
  • Industrialised delivery: Reusable accelerators, CI/CD templates, security baselines, and transformation scripts reduce risk and uncertainty in every engagement.
  • No vendor lock-In: Open conversion standards and architecture governance aligned to your target stack. So you stay in control.
  • Global scale: Cross-border delivery teams with deep legacy expertise and modern platform capabilities.

Powered by Wynxx transformer edition

Our AI Modernisation approach combines deep engineering expertise with industrialised AI delivery, powered by Wynxx Transformer Edition, our proprietary multi-agent AI platform for legacy system understanding, business logic extraction, and governed code transformation.

Wynxx goes beyond code conversion. It understands legacy systems at scale, extracts business logic automatically, and enables governed transformation with built-in testing and documentation.

The Wynxx Transformer Edition is built on our long-term partnerships with major hyperscalers. It incorporates and optimises their key solutions and products into a comprehensive technology stack. This stack addresses nearly all infrastructure and product needs that customers have during their modernisation journey.

This allows us to deliver modernisation with speed, control, and predictable outcomes.
