Modernisation & Migration
"Legacy systems quietly accumulate risk — we move them safely"
Legacy systems carry security exposure, heavy upkeep, and a ceiling on the pace your business can move. We migrate and re-architect applications to modern platforms while keeping everything that is already running fully operational.
What a modern estate gives you
Faster, smoother releases
Automated, repeatable deployment pipelines let teams ship with confidence.
Fully supported runtimes
Current, vendor-supported frameworks and runtimes keep you on solid foundations.
Shared, resilient knowledge
A well-documented codebase the whole engineering team understands and can evolve.
Efficient, elastic scaling
Infrastructure that scales in step with throughput and the demand you actually serve.
Effortless integration
New tools and data sources connect quickly through clean, modern interfaces.
Audit-ready security
A strong, well-evidenced security posture that satisfies compliance and audit teams.
Five modernisation pathways
We pick the right path — and often combine them — based on what the codebase and the timeline can support.
Move the application to cloud infrastructure with minimal code changes. Fast, low-risk first step.
Adopt managed services (databases, queues, autoscaling) without changing the core architecture.
Break a monolith into microservices or event-driven components for independent scalability.
Replace the application entirely on a modern stack when a fresh foundation is the smartest move.
Retire a custom application and migrate data and workflows to a best-fit SaaS platform.
A staged migration with a safe fallback at every step
Assessment & roadmap
Audit codebase, dependencies, data flows, and infrastructure. Output: risk-scored modernisation roadmap with effort and impact per pathway.
Strangler fig & parallel run
Incrementally replace legacy components while keeping the existing system live — routing traffic gradually.
Data migration & validation
Structured migration scripts, dual-write periods, and automated reconciliation — every record migrated intact and reconciled.
Cutover & decommission
Rehearsed cutover plan with tested rollback ready. Legacy decommissioned on a controlled schedule.
How we manage migration risk
Feature parity testing
Automated regression suites verify the new system matches existing behaviour before any traffic is moved.
Rollback at every stage
Each migration phase has a documented, tested rollback procedure — so we can always revert safely with data intact.
Knowledge transfer
Your team is embedded throughout — pair programming, documentation, and structured handover keep the knowledge firmly in-house.
Observability from day one
Logging, tracing, and alerting configured before the first component goes live, ready from the very first deployment.
