Legacy Application Modernisation
Replacing a load-bearing system without an outage
What we build
Modernising systems that cannot be switched off. Dependency and data-flow mapping of the estate as it actually runs, an assessment of what to keep, wrap, rebuild, or retire, strangler-fig sequencing in reversible steps, API facades in front of the legacy core so new work can start immediately, dual-run and reconciliation before any cut-over, data migration verified at every step, and rollback criteria written before the work starts.
Capabilities
- Dependency and data-flow mapping of the estate as it runs, not as it is documented
- A written disposition per component: keep, wrap, rebuild, or retire, with the cost of each
- API facades in front of the legacy core, so new work starts before the rebuild finishes
- Strangler-fig sequencing in reversible steps, each shippable and each stoppable
- Dual-run and reconciliation proving the new path before the old one is switched off
- Knowledge capture from the people who know the old system, before they retire
