Moving an online store to a new platform is one of the largest projects a merchant takes on. Products, customers and order history have to move, URLs change, staff learn new tools, and for a few weeks the risk to sales and search rankings is real. Ecommerce replatforming is sometimes exactly the right call, and sometimes an expensive way to avoid fixing a store that could be repaired. This guide helps you tell the difference and, if you do move, choose the destination with your eyes open.
Ecommerce replatforming: when to switch, and when not to
Signs you have outgrown your platform:
- The version is out of support. Magento 1 reached end of life in June 2020, and stores still running it have had no official security patches since. Every platform version reaches that point eventually.
- Core requirements need fragile workarounds: B2B pricing, several warehouses, multiple currencies or subscriptions bolted on through code nobody wants to touch.
- Integrations are the bottleneck. The ERP, warehouse or marketplace connections you need are unavailable or unreliable on the current platform.
- Running costs keep climbing: app and extension subscriptions, transaction-related fees or hosting that grows faster than sales.
- Nobody can support it. Developers for the platform or version are hard to find.
Not reasons on their own: a slow site, which is usually the theme, images or hosting; a dated design, which a redesign fixes; or one missing feature, which is often an extension away. Deciding when to replatform starts with ruling those out.
SaaS vs open source ecommerce
| Question | SaaS (for example Shopify or BigCommerce) | Open source (for example WooCommerce, Magento Open Source or PrestaShop) |
|---|---|---|
| Hosting and security patches | Handled by the platform | Your responsibility, or your provider's |
| Customization | Within the platform's APIs, apps and theme system | Full access to the code |
| Cost structure | Subscription, app fees and, depending on plan and payment setup, transaction fees | Hosting, development, extensions and ongoing maintenance |
| Upgrades | Continuous, applied by the platform | Planned projects you schedule |
| Data access | Through the platform's export tools and APIs | Direct access to the database |
The SaaS vs open source ecommerce decision is mostly about who you want to be responsible for what. Neither is cheaper in every case, which is why the comparison has to be made on total cost, and why teams that switch ecommerce platforms for price alone are often disappointed.
Where headless commerce fits
Headless commerce separates the storefront from the commerce engine, which then runs the catalog, checkout and orders behind an API. It makes sense for brands with several storefronts, apps or content-heavy sites. For most small and mid-sized stores it doubles the systems to build and maintain without a matching benefit. If you are unsure, start with the platform's own storefront: most commerce engines offer APIs that let a custom front end be added later, while going back from headless is harder.
Compare total cost of ownership, not launch price
Put the current and candidate platforms side by side over three years or more, and include every line: subscription or license, payment processing and any platform transaction fees, app and extension subscriptions, hosting, development of missing features, maintenance and upgrades, staff time, and the migration itself. A realistic total cost of ownership often reverses the first impression. A platform with a low monthly fee can end up costing more than one with a higher fee once the apps it needs are added, and the reverse happens too.
A replatforming checklist before you choose
- Write a platform requirements document: must-have features, integrations (ERP, shipping, payments, marketplaces, email), catalog size and structure, languages and currencies, B2B needs, and who will run the store day to day.
- Inventory the data: products and variants, customers, order history, reviews, gift card balances, loyalty points, blog and content pages. Decide what must move and what can be archived.
- Inventory the search traffic: the URLs that bring visits and links, taken from Search Console and analytics, because each will need a redirect.
- Ask for a scripted demo: have each vendor or implementer show your real scenarios, such as a customer-specific price or a split shipment, rather than a standard tour.
- Pilot the migration with a sample of real products, customers and orders before committing to the full project.
- Agree on ownership after launch: who applies updates, who watches the checkout and integrations, and whom staff call when an order fails. A store that nobody is clearly responsible for drifts back into the state that prompted the move.
The switch itself, with data transfer, redirect mapping and a final sync before launch, is what our e-commerce re-platforming service covers.
Frequently asked questions: ecommerce replatforming
Will we lose search rankings if we switch platforms?
Some movement around launch is common. Lasting losses usually come from missing redirects, lost content or changed internal links. Google's site move guidance recommends mapping every old URL to its new equivalent and keeping the redirects in place for the long term.
Can customer passwords and order history be moved?
Order history, customers, products and reviews usually can. Passwords usually cannot, because each platform stores them differently, so customers set a new one at their first login. Saved cards stay with the payment provider.
Should we redesign at the same time?
Many teams combine the two to avoid building the design twice. The cost is that any change in sales after launch is harder to attribute. Decide based on how much risk you can absorb in the first weeks.
Weighing a move? Our e-commerce platform migration page explains how products, customers, orders and 301 redirect mapping are handled. If your store runs on Magento, an upgrade through Magento 2 development may be the option to compare, and PrestaShop development is another open source destination. Contact us with your current platform, the one you are considering and your main concerns, and we can discuss both routes.
