Replatforming eCommerce: change the platform without forgetting the business system around it.

An eCommerce migration affects catalogue data, customers, orders, integrations, SEO, fulfilment and internal teams. Replatforming should start with evidence that the current platform is the constraint, then map what must survive the move.

Prove that replatforming is actually necessary

Slow delivery, poor performance or recurring bugs can be implementation problems rather than platform limitations. Compare the cost of remediation with the expected benefit of moving.

  • Current technical debt
  • Roadmap blockers
  • Operational pain
  • Supportability and skills

Map integrations before choosing the target platform

ERP, WMS, PIM, CRM, marketplaces, tax, payments and shipping often contain more project risk than the storefront. Document data ownership and interface limitations early.

  • Stock and pricing
  • Orders and fulfilment
  • Customer/account data
  • Product and content feeds

Plan data and SEO as dedicated workstreams

Data migration and URL continuity need their own acceptance criteria. “We imported the products” is not enough if attributes, customer relationships or redirects are incomplete.

  • Data mapping and validation
  • URL inventory and redirects
  • Metadata and content
  • Analytics continuity

Design the cutover and stabilisation period

Launch is not the finish line. Plan freeze periods, delta data, DNS, rollback, monitoring, support and rapid triage for the first trading days.

  • Launch checklist
  • Rollback decision
  • Post-launch monitoring
  • Reconciliation
Frequently asked questions

Questions to consider before you start

How long does replatforming take?

It varies enormously with catalogue, custom functionality, integrations, data quality and testing. A meaningful estimate requires discovery.

Should we redesign at the same time?

Sometimes, but combining every change can increase risk. The decision should reflect business goals and delivery capacity.

Can historic orders and customers be migrated?

Usually, but scope and data model differences need to be assessed carefully.

Can you migrate to or from Magento?

Yes. Magento migration and wider platform migration are both supported.
