Application Modernisation

Move legacy systems off ageing platforms incrementally, without a risky big-bang rewrite or a feature freeze.

Legacy systems are rarely replaced in one go — the successful ones are strangled gradually, with new functionality built alongside the old and traffic moved across piece by piece. We assess what you have, identify which parts carry real business logic worth preserving, and plan a migration that keeps the lights on throughout. Your team keeps shipping features while the platform underneath changes, and every migration step has a tested route back.

What this includes

  • Legacy assessment and migration strategy
  • Incremental re-platforming, no big-bang rewrite
  • Data migration with verification and rollback

How we deliver

From first workshop to live service

Seven stages, one accountable team. Each stage ends with something you can review and a decision that is yours to make — nothing moves forward without your sign-off.

Discover

Typically 2–4 weeks

Workshops with your stakeholders, interviews with the people who will use the product, and a hard look at the systems it has to live alongside.

What you get

  • Problem statement and success measures
  • User journeys and current-process map
  • Risky assumptions, tested
Your decision point You decide whether to proceed — with no obligation to use us for the build.

Plan

Typically 1–2 weeks

Discovery becomes a delivery plan you can budget against: what gets built first, what waits, and what it is likely to cost.

What you get

  • Prioritised backlog and release roadmap
  • Architecture recommendation
  • Costed estimate as a range, assumptions written down
Your decision point Scope, budget range and change process agreed in writing.

Design

Runs a sprint ahead of build

Clickable prototypes tested with real users, then a design system your engineers can build from without guesswork.

What you get

  • Tested prototypes of the core journeys
  • Design system and component library
  • Accessibility checked against WCAG 2.2 AA
Your decision point You approve each journey before it goes into a sprint.

Build

Two-week sprints

Small senior teams shipping working software every fortnight, in your repositories, against a backlog you control.

What you get

  • A demonstrable increment every sprint
  • Peer review and automated tests on every change
  • Documentation written as we go
Your decision point Sprint review with you; reprioritise freely between sprints.

Assure

Continuous, plus pre-release

Quality built into the pipeline rather than discovered by a customer — regression, performance and security checks before anything ships.

What you get

  • End-to-end regression suite on key journeys
  • Load and performance testing
  • Dependency and security scanning
Your decision point Release readiness review against agreed acceptance criteria.

Deploy

Release-ready from the first sprint

Infrastructure as code, automated pipelines and monitoring, in your own cloud accounts — so going live is routine and reversible.

What you get

  • Infrastructure as code in your cloud account
  • CI/CD with automated rollback
  • Monitoring, alerting and runbooks
Your decision point Go-live sign-off and a rehearsed rollback plan.

Support & evolve

Ongoing, or a clean handover

A support agreement with response times in writing and time each month for improvements — or a structured handover to your own team.

What you get

  • Support agreement with defined response times
  • Monthly improvement allocation
  • Handover sessions and pairing, if you take it in-house
Your decision point You own everything — code, infrastructure and documentation.
