01

The Business Challenge

A UK retailer was trading on a heavily customised Magento store that had passed through several agencies. Upgrades had been deferred for years, extensions conflicted, and every change carried the risk of breaking checkout.

The business needed to modernise the platform without a risky big-bang rebuild and without pausing trading.

02

Existing Technology Environment

  • Magento with extensive legacy customisation and third-party extensions
  • Manual deployment processes with no automated testing
  • ERP integration built as undocumented point-to-point scripts

03

Our Approach

  1. 01Started with a full architecture and code review to map customisations, extension conflicts and upgrade blockers.
  2. 02Prioritised a stabilisation phase — removing dead code, replacing conflicting extensions and bringing deployments under CI/CD — before attempting the platform upgrade.
  3. 03Executed the upgrade in planned stages with automated regression testing around checkout and order flows.
  4. 04Re-engineered the ERP integration as a documented, monitored integration layer.

04

The Solution Delivered

  • A current, supportable Adobe Commerce platform with a clean upgrade path.
  • Automated deployment pipeline with regression tests protecting the revenue-critical flows.
  • A monitored ERP integration replacing fragile legacy scripts.
