Legacy Modernization

Move off the old system without stopping the business.

The approach

Rewrites fail when they try to happen all at once. We modernize incrementally, strangling the legacy system service by service, so you keep operating throughout and can stop at any point with value banked.

What you get out of it

  • No big-bang cutover risk
  • Each phase independently valuable
  • Data migrated with verification, not hope

What you receive

  • Legacy audit & risk map
  • Phased migration plan
  • Incremental replacement services
  • Data migration & validation

Typical stack

Indicative, not fixed. We pick for what your team can maintain after handover.

Delivery

Every two weeks, something you can open.

Six phases. Each one ends in working software, in an environment you can log into and judge for yourself. Never a status report as the only evidence.

  1. 1–2 weeks

    Discover

    We map the problem, the constraints and the people. You leave with an architecture direction, a scope and an estimate you can hold us to.

  2. 2–4 weeks

    Design

    Flows, interfaces and data models get settled while they are still cheap to change. Prototypes meet real users before anyone writes code.

  3. Ongoing

    Build

    Two-week increments, each ending in a demo. Working software in an environment you can log into. Not a status report.

  4. 1–2 weeks

    Harden

    Load testing, security review, accessibility pass, and the failure cases nobody enjoys writing. This is the step most projects skip.

  5. 1 week

    Launch

    Staged rollout, monitoring live, rollback tested in advance. Someone is watching the graphs on the day.

  6. Continuous

    Evolve

    Support under an agreed SLA, and a next round driven by what usage data actually shows.

Next step

Need legacy modernization?

Send over the problem and any constraints you already know about. We will come back with an approach, a rough shape of the work and an honest view on feasibility.
