Replatforming is one of the most challenging things an ecommerce business can undertake. Data migrations go wrong. Redirects get missed. The new site launches slower than the old one. We’ve seen it all, and we’ve built a methodology specifically designed to avoid every one of those pitfalls and give you migrations without migraines. Our replatforming process is thorough, phased, and obsessively tested. We move your data, your SEO equity, your integrations, and your team’s confidence — intact — to your new platform. ### **This is for you if:** - You’re stuck on a legacy platform that’s holding your business back. - You’ve tried to replatform before and it went badly — and you need a team that won’t repeat those mistakes. - You’re evaluating platforms and want a partner who can handle the full migration, not just the design. ### **What you’ll get from this:** - A phased migration plan with clear milestones, risk mitigation, and rollback protocols. - Full data migration: products, customers, orders, and all the edge cases your previous agency missed. - SEO continuity: redirect mapping, structured data, and post-launch monitoring. - A launch that your customers don’t notice — which is exactly the point. [Get in touch](https://www.takefortytwo.com/en/contact/) ## Frequently Asked Questions How long does a typical replatforming take?3 – 6 months for mid-size B2B/B2C catalogs. Less if your data is clean, more if there are integrations (ERP, PIM, custom pricing engines, multi-storefront). We’d rather take 5 months and launch right than 3 months and spend 2 more recovering. Read [Seven Immutable Laws of Ecommerce Replatforming](https://www.takefortytwo.com/en/blog/seven-immutable-laws-of-ecommerce-replatforming/) for the methodology. What goes wrong in most migrations?Three things, almost every time: redirects that miss edge cases (faceted URLs, paginated archives), customer/​order data that doesn’t transform cleanly, and post-launch SEO regression because the [SEO Migration](https://www.takefortytwo.com/en/services/seo-migration/) workstream wasn’t a first-class workstream. We’ve built the methodology around exactly those three. Which platforms have you replatformed to and from?We’ve handled most combinations of BigCommerce, Shopify, Magento (Adobe Commerce), Prestashop, Squarespace, and Lemonstand, in both directions. Public examples: [EGO Magento → BigCommerce](https://www.takefortytwo.com/en/case-studies/ego/), [IGT Prestashop → BigCommerce](https://www.takefortytwo.com/en/case-studies/igt-microelectronics/), [Shimoda Squarespace → BigCommerce](https://www.takefortytwo.com/en/case-studies/shimoda/), and [Cinetics Lemonstand → BigCommerce](https://www.takefortytwo.com/en/case-studies/cinetics/). The platform pair matters less than the method: redirects, data transformation, and SEO migration fail the same way everywhere, and that’s what the methodology covers. We don't know yet which platform to move to. Can you help us decide?Yes, we can: that’s [Platform Selection & Evaluation](https://www.takefortytwo.com/en/services/platform-selection-evaluation/), a separate engagement that runs before the build starts. We don’t have a platform agenda, so the recommendation reflects fit, not affiliation: we’ve migrated stores across most combinations of BigCommerce, Shopify, Magento, Prestashop, and Squarespace. Deciding the destination properly is far cheaper than discovering mid-build that it’s wrong. How do you minimize launch risk?Phased migration with rollback protocols at every milestone. Staging environment that mirrors production. Pre-launch crawl and inventory. Post-launch monitoring with [Data Migration](https://www.takefortytwo.com/en/services/data-migration/) validation and weekly SEO reports for 90 days. The launch your customers don’t notice is the one that worked. We have an existing dev team. Can you work with them or do you replace them?Both modes work: we can run the full replatforming end to end, or plug in around your existing team. In the shared mode we typically lead the SEO migration, data migration, and platform setup while your developers build the front-end they know best. The split depends on capacity and where the gaps are, and we agree on it before the project starts. ## You might also like #### SEO Migration Years of SEO equity can evaporate in a careless migration.
