About this service

Legacy systems don't just hold you back — they accumulate risk. Every month you delay modernization is another month of security vulnerabilities, scaling limitations and developer productivity loss. But a rushed or poorly planned migration can be far more damaging than staying put. We plan and execute migrations methodically — with thorough dependency mapping, data validation, parallel running periods and staged cutovers — so your business never skips a beat and you arrive on the other side with infrastructure you're proud of.

How it automates

From a system nobody dares touch to one you can build on

It starts the moment the legacy platform blocks a change. Here is what used to happen, and what happens instead.

Before

Done by hand

  • The software runs on unsupported technology
  • Only one person understands how it works
  • Every change risks breaking something unrelated
  • Security patches are no longer available

After

Handled automatically

  • Mapped. Every feature, integration and data path documented
  • Rebuilt. Moved onto a supported, modern stack
  • Migrated. Data transferred and reconciled record by record
  • Switched over. Cut across with a tested rollback plan

Scope this for my business
What we deliver

Everything included

Every project is scoped to your needs. These are the capabilities we bring to this service.

01

Migration Assessment & Planning

Full dependency mapping, risk analysis, data inventory, compatibility testing and a detailed migration plan with a realistic, business-approved timeline.

02

Re-platform & Re-architecture

Choose the right strategy — lift-and-shift for speed, re-platforming for better economics, or full re-architecture where the old design can't scale.

03

Database Migration

Verified data transfer with schema transformation, referential integrity validation, parallel running verification and rollback snapshots at every stage.

04

Cloud Provider Migration

Migrate from on-premises or between cloud providers — AWS, GCP, Azure, Cloudflare — with Terraform-managed infrastructure on the target side.

05

Staged Cutover & Rollback

Traffic split strategies, feature-flag-controlled cutovers and a tested rollback procedure mean the go-live moment is boring, not terrifying.

06

Post-Migration Optimisation

Right-size compute, tune caching, optimise database queries and reduce cloud costs in the weeks after migration while performance is under close observation.

How we work

A clear path from idea to live

You see progress at every stage, and nothing is built without your approval.

  1. 1

    Assess

    Inventory systems, dependencies, data volumes and business continuity requirements.

  2. 2

    Plan

    Define target architecture, migration strategy, timeline and rollback criteria.

  3. 3

    Prepare

    Build and validate the target environment; run data migration dry-runs.

  4. 4

    Migrate

    Execute the live data migration with real-time validation.

  5. 5

    Validate

    Parallel run old and new systems; compare outputs and confirm correctness.

  6. 6

    Cutover

    Staged traffic switch with instant rollback capability until confidence is confirmed.

Why it matters

What changes for your business

The practical difference you can expect once the work is done.

Every record accounted for

Multi-pass validation, checksums and parallel running confirm every record has arrived correctly before the old system is retired.

Minimal business disruption

Phased, parallel cutovers mean your business continues operating normally throughout — no planned outage windows for most projects.

Lower infrastructure cost

Right-sized, modern infrastructure is usually cheaper to run and maintain than the ageing environment it replaces.

Improved security posture

Move from unpatched, EOL infrastructure to modern platforms with automated patching, managed identity and encryption by default.

Developer productivity gains

Modern tooling, proper CI/CD and clean infrastructure dramatically improve how fast your team can ship new features.

Future-ready platform

A properly architected target environment is a foundation you can build on — not another legacy system in the making.

Questions

Common questions

Something else on your mind? Ask us directly and you will get a straight answer.

Will our business have downtime?

We plan migrations to avoid it. Old and new systems usually run side by side, and the final switch is scheduled for a quiet time with a tested rollback plan.

How do you make sure no data is lost?

Data is migrated in rehearsals first, then reconciled record by record with counts and checksums before the old system is retired.

Do we have to rebuild everything?

No. Sometimes moving the existing system to better infrastructure is enough. We recommend the least disruptive option that solves the real problem.
