Legacy Modernisation & Cloud

Move At The Speed Your Market Now Demands.

Your customers expect real-time speed and personalisation, and AI keeps raising the bar. A legacy core holds you back - batching, delays, re-keying, reconciliation. We rebuild critical workloads on cloud infrastructure so you move at market speed. No forced replacement, no Big Bang.

A legacy core modernised onto cloud infrastructure by phased, parallel migration

Legacy Systems Slow You When Markets Speed Up

Most businesses are trapped in the same pattern: the systems keeping you profitable today are the same systems stopping you from building tomorrow. You can't make them move faster without breaking them. New products take months to launch because the core won't allow it. After-acquisition integration stalls because systems don't talk. Competitors can redesign in weeks. You move in quarters. Per Eurostat, 53% of EU enterprises used paid cloud services in 2025, up from 45% two years earlier - the shift off legacy infrastructure is accelerating, and the businesses still tied to it lose ground. Every release cycle, the gap widens.

What You Walk Away With

A detailed audit of your current systems: what's holding you back, and what has to change before new capability - AI, integration, speed, scale - can be deployed.

A modernisation roadmap, phased by business outcome, not by technology risk. Outcome first ("launch this product faster", "integrate after acquisition"); technology second.

A cloud-native production system live alongside your legacy infrastructure, running real work with your team - not a prototype, not a simulation.

Clear decommission and migration planning for the systems being replaced, with rollback proven at every stage.

A handed-over architecture your teams own and extend, with no lock-in to proprietary components.

How The Work Typically Runs

01
3-4 weeks

Assess

We audit your core and adjacent systems: performance, architecture, compliance risk, AI readiness. Output: a readiness report and a prioritised modernisation roadmap.

02
8-12 weeks

Pilot

A real workload - a new product, an acquisition integration, or a high-value transaction type - runs on the new platform, live with your team. Output: before-and-after metrics on speed, cost and capability.

03
12-20 weeks

Expand

More workloads migrate to the modern core. Legacy systems are decommissioned on a schedule you control. Output: adoption and cost metrics per phase.

04
2-3 weeks

Handover

Your team owns the modern platform. We stay available for questions.

Minimally invasive by default: 
we run the new system alongside your legacy core, so your operational load stays low and the risk stays managed.

The Proof Is On Our Impact Page

15+ Years

Questions We Get Asked

+
How Is This Different From A Big Bang Core Replacement?
Two ways. We run the new platform alongside your legacy core, so work keeps flowing while we migrate. And we prove each phase in production with your team before the next one commits - no surprises on go-live. Big Bang replacements fail when safety can't be proven until go-live.
+
How Long Does A Full Migration Take?
Typically six to nine months for a full shift, depending on your core's complexity and which workloads you migrate first. We phase it by business outcome, not by technology, so you see wins early - new capability, faster integration - before any legacy decommission.
+
What About Compliance And Audit During The Migration?
Built in from day one. The new platform maintains every control your legacy system provides today, and adds the ones you need next. Monitoring and rollback run in parallel throughout, so you can pause or reverse any phase.
+
What Size Of Organisation Is This For?
Mid-market and up, across all industries. Enterprise case-by-case where the scope is tight.
