Ecommerce replatforming, from decision to launch

Common, legitimate triggers: the platform has reached end of life or stopped receiving security updates (Magento 1, Shopware 5); hosting, patching and extension maintenance cost more than the store can justify; the platform blocks something the business needs, such as new markets, B2B pricing, a headless storefront or a modern checkout; or the team spends its time keeping the platform alive instead of selling.

Weak triggers are a dated theme, a single missing feature an app could provide, or a sales demo. A redesign or a targeted integration is often cheaper than a new platform. We say so when that is the case.

We start from what the store actually does: catalog structure and product types, pricing rules and customer groups, markets, languages and currencies, fulfilment and ERP/WMS integrations, marketplaces and feeds, content and SEO footprint, and the custom features someone once paid for. Each requirement is marked as must-have, replaceable or retirable. That list, not a feature matrix, is what the candidate platforms are compared against.

The data model rarely matches: attributes, variants, bundles and category trees behave differently on the target. URL structures change, so every relevant URL needs a destination and a 301 redirect. Plugins and apps do not transfer; their data and behaviour need a replacement, a rebuild or a decision to retire them. Integrations with ERP, accounting, carriers and marketplaces must be re-pointed and tested. Customer passwords usually cannot move to a hosted platform. None of this is exotic; it just has to be found before launch rather than after.

Compare the full picture over several years: platform subscription or licence, hosting and security, payment and transaction fees, apps and extensions, development and agency time, the migration itself, and the internal time to run the store. A cheaper plan with five paid apps and a custom integration may cost more than it looks. We help you build that comparison from your real requirements; we do not sell platform licences.

Once the target is chosen, replatforming becomes a managed migration: source audit, data mapping, trial migration and sign-off, SEO and redirect plan, integration cut-over, content freeze, delta migration, launch and post-launch QA. Large stores are often moved in phases, for example catalog and content first, then customers and orders, then integrations, so each step can be verified.

We are a migration team, not a platform reseller. That means the recommendation follows your requirements and data, and the same person who assessed the risks runs the migration. Platform-specific build work such as a custom theme or complex app development can be done by your agency or partners; we coordinate the data, SEO and launch side with them.
