Why merchants move off Magento
Magento Open Source and Adobe Commerce give you full control of the codebase, hosting and checkout - which is exactly why they're expensive to keep running. Someone has to patch PHP and Magento security releases, manage the server or cloud infrastructure, and keep PCI compliance current for the checkout you host yourself. Shopify takes hosting, PCI compliance and platform security patching off your team's plate in exchange for less low-level control.
A common trigger is that the ongoing cost of a developer or agency to maintain a Magento instance no longer matches the size of the store, especially once Magento 1 (long past end-of-life) or an ageing Magento 2 setup starts accumulating unpatched extensions.
What actually changes in the data model
Magento's product catalog is built on an EAV (Entity-Attribute-Value) structure, which lets you define arbitrary custom attributes per product type. Shopify's product model is simpler: a product has a fixed set of core fields plus up to three variant option dimensions (like size and color) and metafields for anything else. Magento configurable products and custom options map onto Shopify variants and metafields, but the mapping isn't 1:1 - attribute sets with many custom attributes usually need a metafield scheme designed on purpose, not attribute-by-attribute autoconversion.
Categories are another real difference: Magento lets you nest categories arbitrarily deep and assign a product to many of them with different display settings per store view. Shopify collections are flatter - manual or rule-based ("smart") lists rather than a true category tree - so a deeply nested Magento catalog needs a deliberate collection structure, not a straight export.
URLs, redirects and what breaks silently
Magento URL keys and rewrites are configurable per store view. Shopify enforces URL patterns such as /products/{handle}, /collections/{handle}, /pages/{handle} and /blogs/{blog}/{handle} that cannot be restructured at will. Each relevant indexed Magento URL therefore needs a documented Shopify destination and, when the address changes, an explicit 301 redirect. A map built and tested before launch reduces avoidable 404s and SEO risk, although no migration can guarantee unchanged rankings.
Extensions, checkout customizations and multi-store
Magento's extension ecosystem and its ability to customize checkout, pricing rules and admin workflows in code have no direct Shopify equivalent - Shopify uses an App Store plus, on Shopify Plus, Checkout Extensibility and Shopify Functions for custom checkout logic. Every custom Magento module needs an explicit decision: is there an equivalent app, does it need a custom app built on Shopify's APIs, or is the functionality dropped. The same applies to Magento multi-website/multi-store setups, which don't translate directly to Shopify's single-store-plus-Markets model for international selling.
Our managed migration process maps this out during the assessment - cataloging your active extensions and custom modules before quoting the work, not discovering them mid-migration.
Frequently asked questions
Can Shopify handle Magento's custom product attributes?
Yes, through metafields, but they need to be defined and mapped deliberately - Shopify has no automatic equivalent to Magento's EAV attribute sets. We map your actual attribute usage during the assessment rather than migrating every attribute Magento happens to have defined.
Will my Magento URLs redirect automatically?
No. Shopify's URL structure is fixed, so every meaningful Magento URL needs an explicit 301 redirect to its new Shopify equivalent. This is core to the migration plan, not an optional add-on - see our SEO & Redirect Migration service.
What happens to my Magento extensions and custom modules?
Each one gets evaluated individually during the assessment: replace with an existing Shopify app, rebuild as a custom app or theme customization, or confirm it's no longer needed. We flag this list before scoping the project, not after.
Can I keep multi-store or multi-website functionality?
Magento's multi-website model doesn't map directly onto Shopify. Depending on what you actually need - separate brands, separate regions, separate currencies - the right Shopify equivalent might be Shopify Markets, a second store, or a Shopify Plus Organization. We help you pick based on the actual requirement, not a generic answer.
