Moving a live store from Magento to Shopify sounds like the kind of project that goes badly. The fear is rarely about Shopify itself; it’s about losing the search rankings you spent years earning, dropping orders during the switch, or mangling a catalogue in transit. All three are avoidable. Done with a proper plan, a replatform is routine rather than risky.
Why teams make the move
Magento is powerful and, for many businesses, more platform than they need: heavier to host, costlier to maintain, and dependent on specialist help for routine changes. Shopify trades some of that flexibility for something a team can run itself. The decision usually comes down to whether you want to own infrastructure or get out of that business entirely. Neither is wrong; what matters is doing the move without paying for it in lost traffic and revenue.
The three real risks
A migration has to protect three things, in roughly this order of fragility:
- Search rankings. Your existing URLs carry accumulated SEO value. Change them without care and you lose the traffic that took years to build.
- Uptime. The store can’t go dark during the switch; every minute down is a lost order and a frustrated customer.
- Data integrity. Years of products, variants, customers, and order history have to arrive intact and correctly structured on the other side.
Everything in the playbook below exists to defend those three.
The playbook
- Audit before you touch anything. Catalogue every product, category, URL, and integration. You can’t migrate what you haven’t mapped, and the audit is where you find the surprises while they’re still cheap.
- Clean the data before importing it. This is where most migrations go wrong. Catalogues accumulate inconsistent formatting, missing images, and tangled category structures, and importing a mess only moves the mess. Standardise and clean first; scripted cleanup beats manual fixing at any real scale.
- Map every old URL to its new equivalent. Build a complete old-to-new URL map and put a 301 redirect on each one. A 301 tells search engines the page has moved permanently and to carry the ranking across. Skipping this is the single most common way stores lose traffic in a replatform.
- Preserve what search engines read. Keep page titles, meta descriptions, and structured data intact or improved, and don’t change URL structures gratuitously. Every unnecessary change is risk for no reward.
- Test on a staging store first. Migrate into a non-public store, check the data, the redirects, and the templates, and fix problems before any customer sees them.
- Plan the cutover. Sequence the DNS switch so there’s no gap in availability. Do it at a low-traffic time, with the redirects already live, so the transition is invisible to customers.
- Verify after launch. Confirm the redirects resolve, submit an updated sitemap, watch rankings and order flow for the first weeks, and fix any straggler URLs quickly.
How long it takes
The honest answer is: it depends on the size of the catalogue and how clean the data is. A small store with a few hundred tidy products is a couple of weeks. A large catalogue with messy, inconsistent data is dominated by the cleanup, not the migration itself, which is exactly why the audit comes first.
A replatform handled this way is undramatic by design: rankings hold, the store stays up, and the data arrives clean. If you’re facing a migration you can’t afford to get wrong, it’s the kind of work our project rescue practice handles end to end.
