- Legacy Modernisation

Old code.
New
future.

Legacy systems don't have to hold you back. We re-architect, refactor, and modernise incrementally - no big-bang rewrites, no downtime, no lost institutional knowledge.

- Modernisation Strategies

Four proven approaches

We choose the right strategy for your system - not the most complex one.

Incrementally replace legacy functionality with modern services, routing traffic to new components as they're built. The legacy system shrinks until it can be retired - with zero big-bang rewrites.

Best when

Large monoliths that can't stop running. Most common choice.

Legacy Assessment & Roadmap

Before touching a line of code we audit the system - mapping dependencies, cataloguing the debt, interviewing the team, and producing a phased modernisation roadmap with clear milestones and business cases for each phase.

  • ›Full codebase & dependency audit
  • ›Technical debt quantification
  • ›Risk assessment & migration sequencing
  • ›Business case & ROI modelling per phase

Incremental Re-architecture

We use the Strangler Fig pattern to modernise without big-bang rewrites. Each module is extracted, rewritten with tests, and deployed to production independently - the system keeps running throughout.

  • ›Strangler Fig pattern execution
  • ›Module-by-module extraction & rewrite
  • ›Data migration with zero-downtime cutover
  • ›Feature parity verification at each step

Downtime during migration

Technical Debt Payoff

Systematic elimination of the patterns that slow your team down - untested code, tightly coupled modules, missing documentation, outdated dependencies, and security vulnerabilities that have accumulated over years.

  • ›Test coverage from 0% to 80%+ in phases
  • ›Dependency upgrades & vulnerability patching
  • ›Documentation generation & architecture diagrams
  • ›Code quality gates enforced in CI

75% of IT budgets are spent maintaining legacy systems. That's budget that should be building new things.
