Magento to Shopify Migration: A Practical Guide

If you are weighing up a Magento to Shopify migration, you are probably not doing it for fun. You are doing it because Magento has quietly become the most expensive line item in your business that nobody talks about: hosting, security patches, developer retainers, and the low hum of anxiety every time a new version drops.

You are not alone in this. The number of active Magento stores has fallen from a peak of roughly 162,000 in late 2021 to around 112,000 by early 2026. That is not ecommerce shrinking. It is merchants leaving. This guide walks through why the exodus is happening, what a move to Shopify actually involves, and how to protect the SEO equity you have spent years building.

Why brands are leaving Magento

The trigger for most Magento replatform decisions is not one dramatic failure. It is accumulation. Adobe's ownership slowed the pace of open-source development, the pool of affordable Magento developers has shrunk, and self-hosting costs keep climbing while the platform demands more of your team just to stand still.

There is also a hard deadline. Regular support for the Magento 2.4.6 release line ends on 11 August 2026, and running an unsupported version puts your PCI compliance and your customer data at risk. Adobe publishes its own software lifecycle policy if you want to check where your version sits. For a lot of UK retailers, that date has turned a someday project into a this-year project.

None of this means Magento is a bad platform. For enterprises with genuinely complex, custom logic it can still be the right tool. But most mid-market brands are paying enterprise overheads for capability they never use.

What a Magento to Shopify migration actually involves

A migration is not a copy-and-paste job, and any agency that tells you otherwise is selling you a headache. At a practical level, a Magento to Shopify migration breaks down into a handful of workstreams that need to run in order.

Data migration. Products, variants, collections, customers, and order history move across. Custom attributes and configurable products are where Magento data gets messy, so this stage needs care, not just a plugin.Theme and front-end build. Shopify's theme architecture is different. You rebuild the storefront rather than porting the old one, which is a good moment to fix the design debt you have been living with.Apps and integrations. Your ERP, PIM, reviews, subscriptions, and payment flows all need Shopify equivalents or custom work. List every integration early; the forgotten ones cause the delays.URL and SEO mapping. Every old URL needs a plan. More on this below, because it is the part most likely to hurt you if it is rushed.Testing and cutover. QA on real data, a redirect check, then a controlled go-live. Rushing this stage is how brands lose a weekend of sales.

For a mid-sized catalogue you should expect a project measured in weeks, not days. Our own Shopify migration services run on a fixed scope so you know what you are getting before anyone touches your data. We have delivered this kind of work across more than 100 projects in over 12 years, and the pattern holds: the migrations that go wrong are the ones that skipped the mapping stage.

Protecting your SEO when you migrate Magento to Shopify

This is the section to read twice. When you migrate Magento to Shopify, your URL structure changes whether you like it or not. Shopify enforces prefixes like /products/ and /collections/, so even a page with the same name lives at a new address. Without a redirect plan, you hand your hard-won rankings back to Google.

The fix is a one-to-one 301 redirect map: every old URL pointing to its exact new destination in a single hop. A 301 tells Google the move is permanent and passes on nearly all of the page's ranking power. Avoid the two classic mistakes: blanket redirects that send everything to the homepage, and redirect chains that bounce a visitor through three URLs before they land.

Migrations do not lose rankings. Rushed redirect maps lose rankings. The technical move is the easy part; the discipline is in the detail.

Expect a short dip. Smaller stores usually stabilise within a few weeks, larger catalogues can take a couple of months, and clean redirects plus preserved metadata shorten the recovery. Shopify's own SEO migration guide is a sensible reference, and it is worth pairing the move with a hard look at site speed and Core Web Vitals, since a faster storefront is one of the quiet wins of leaving self-hosted Magento behind.

What migration costs, and what it saves

Migration project fees vary enormously with catalogue size and integration complexity, from a few thousand pounds for a simple store to well into six figures for a heavily customised Adobe Commerce build. That range is real, and anyone quoting a single number without seeing your setup is guessing.

The more useful comparison is ongoing cost. Adobe Commerce Cloud typically starts around $22,000 a year and climbs with order volume, before you add hosting, patching, and developer time. Shopify Plus sits near $2,500 a month with predictable scaling and no server to babysit. For most mid-market brands the three-year total cost of ownership drops sharply, which is usually what turns a nervous board into a decisive one.

Migration is not a growth strategy

Here is the honest bit an agency should tell you before you sign anything. Moving to Shopify will make your store cheaper to run and faster to change. It will not, on its own, sell more. Most Shopify brands do not have a traffic problem, they have a conversion problem, and a replatform does not fix a checkout that leaks or product pages that fail to persuade.

So treat the migration as the reset, not the finish line. The brands that see real returns use the move to clean up the storefront, then keep optimising once the dust settles. If your current store has visitors but flat sales, our piece on why your Shopify store has traffic but no sales is worth a read, and our Conversion Growth Retainer is built for exactly the phase that comes after go-live.

The practical takeaway

If you are on Magento and the support deadline is forcing your hand, do not panic-migrate. Plan the data, plan the redirects, and be honest about which integrations you genuinely need. Get those three right and the move is calm rather than chaotic. From our base in Glasgow we run these projects for brands across the UK and further afield, with a senior team and no work outsourced, so the person scoping your migration is the person doing it.
