Platform Migration

Platform migration describes the movement from one technology platform to another. In ecommerce, this often means moving from an existing commerce platform, CMS, custom website, legacy stack or monolithic system to a newer platform or architecture.

A platform migration can include product data, customer records, order history, content, URLs, redirects, integrations, payment settings, analytics, user permissions and operational workflows. It is not limited to copying content from one system to another.

Platform migration is often one part of a wider ecommerce replatforming programme. Replatforming describes the broader business change. Platform migration describes the movement of systems, data and functionality that enables that change.

Platform migration matters because moving from one platform to another can expose hidden dependencies, poor data quality, fragile integrations and unclear ownership. These issues often remain invisible until the business attempts to move them.

For ecommerce teams, migration affects commercial continuity. A poorly planned migration can disrupt trading, break customer journeys, damage SEO visibility, interrupt order flows or create operational workarounds. A well-governed migration protects the value already built in the existing digital estate while enabling future improvement.

A retailer moving from an old ecommerce platform to a new SaaS commerce platform may need to migrate product catalogue data, customer accounts, order records, CMS content, URL redirects, analytics tracking and integrations with ERP, payment and fulfilment systems.

The platform migration is the movement of those assets and connections. The wider replatforming programme includes the business case, requirements, governance, vendor selection, testing, launch planning and post-launch optimisation around that move.
