How we modernise

In stages, with the business running throughout.

We assess the estate, steady what is fragile, move it in controlled slices and accept each slice on evidence agreed before the work started. The target state is chosen system by system, and the handover leaves your team able to carry it forward.

Answers from our published service information

01 / How we approach it

Modernisation as a series of bridges.

Legacy estates contain hard-won business logic whose original authors have long since left. A rebuild claims to recreate that logic. In practice it recreates the parts the team remembers and quietly drops the rest.

So we treat modernisation as a series of bridges. We keep what is stable, put modern interfaces in front of it where other systems need to reach it, and migrate the painful slices on a schedule the team can absorb. The existing system stays live throughout. Sometimes a rebuild is the right call, and we set out when.

02 / How we work

Keep what works.
Improve it in stages.

Scope and timing are agreed before work starts, and you decide after each stage whether to continue.

  1. 01

    Assess.

    We map the estate, its dependencies, patch status, test coverage and recovery readiness, then rank what to keep, wrap, migrate or retire by risk and value.

    You leave withPriorities, a target architecture, and cost and timeline ranges.
  2. 02

    Stabilise.

    Where something is hurting the business today, such as failing deployments, memory or queue problems, we steady it first. Remediation is scoped as delivery work.

  3. 03

    Migrate.

    We move the system in controlled slices, planned so the business keeps running. Where the application allows, old and new run side by side while a slice moves.

    You leave withEach slice moved, with its rollback approach agreed.
  4. 04

    Validate.

    A slice is accepted once its business behaviour is shown on the evidence agreed before the work started: tests, comparison with the existing system, performance and security checks.

    You leave withAccepted behaviour, documentation and a team ready to run it.

Evidence throughout. Every stage ends with something you can check, so the decision to continue is yours.

How we modernise

03 / Target state

Where each system ends up is decided one by one.

What moves and what stays is settled in the assessment, on cost, risk, dependencies and what the business needs next.

  • AWS

    Where the business already runs on AWS, or a workload suits its services. We work with the cloud you have rather than moving you between them.

  • Azure

    A natural home for many .NET workloads, and for businesses already on Microsoft 365 and Entra ID. Our published .NET Framework to .NET Core engagement was delivered on Azure.

  • Hybrid

    Some systems move and some stay, connected through managed integrations, where residency, latency or an on-premises dependency decides it.

  • Retained on-premises

    Keep the system where it is and modernise the code, releases and monitoring around it. That is a valid target state.

Cloud is not always the answer, and moving an application does not fix its design. A tangled system on new hosting is still tangled, and often costs more to run. Lifting and shifting to containers suits some workloads; for most it postpones the real work. The hosting side is covered under infrastructure.

04 / While the work moves

Built so the business never waits on a cutover.

The work moves in slices the team can absorb, each with a decision point, so you are never committed to a single large cutover.

  • Continuity

    The existing system stays in service while the work happens. A planned cutover is used only where it is genuinely the safer option.

  • Testing

    Before a slice moves, we agree the evidence that will prove it: tests, comparison with the existing system, and performance and security checks. Where tests are thin, adding them comes first.

  • Rollback

    Each slice has its rollback approach agreed before it goes live, so a problem means stepping back rather than an incident.

  • Observability

    Logging, metrics and alerts go in with the change, so the team can see how a new slice behaves in production.

  • Handover

    Documentation, runbooks and decisions are written as we go, not at the end, so your team can carry the codebase forward after we leave.

Common questions

What leaders ask before the work starts.

What does a Modernisation Assessment cover, and how long does it take?

Scope and timing are confirmed before the assessment begins. It covers dependency mapping, risk-ranked priorities, a target architecture, patch status, test and regression coverage, recovery readiness, and cost and timeline ranges, with a clear 'wait' option where that is the right call. Any remediation is scoped separately as delivery work.

Can the system stay live during the work?

In most cases, yes. Our default is phased delivery where the existing system stays in service throughout. A planned cutover is used only where it is genuinely the safer option, and the assessment says which approach fits each part of the estate.

The next step

Start with a Modernisation Assessment.

It maps your estate, ranks what to keep, wrap, migrate or retire by risk and value, and gives you cost and timeline ranges. Already have a modernisation quote? We can pressure-test it as part of the assessment.
