Magento to Shopify Migration Checklist: How to Switch Platforms Without Breaking Your Business

Every eCommerce team considering this move asks some version of the same question: “We want to move to Shopify, but what actually breaks?" The honest answer is: more than most teams plan for, and almost always the things that hurt revenue first.

The fear isn’t irrational. Orders in-flight during migration. Customers who can’t log in to track a purchase. Inventory counts that drift out of sync. Checkout flows that worked on Magento but don’t exist natively on Shopify. And underneath all of it, the slow SEO drop that doesn’t announce itself until three months later.

This is why a Magento-to-Shopify migration is better understood as a business continuity challenge rather than a data transfer exercise.

In this checklist, we’ve broken down what a Magento-to-Shopify migration really demands, so you’re not just following steps but making the right decisions at each stage of the transition.

Protecting your ROI starts with prioritizing business continuity over everything else. Make sure your revenue-critical functions, orders, payments, checkout, and inventory are working reliably from day one.

Once that foundation is stable, move to your operations layer: ERP, 3PL, and support tooling. SEO validation comes after that, not alongside it. Most migrations lose ROI when teams try to tackle all three layers at once without a clear sequence.

Most of these failures aren’t inevitable, they’re planning gaps. The checklist below is structured to close them before they reach your customers.

Before anything moves, you need a clear picture of what you actually have. This means understanding every extension, custom module, and what your team and customers depend on. This is a critical first step in the Magento-to-Shopify migration process and defines what to check before migrating.

Most Magento stores carry years of layered decisions that aren’t fully documented. This is where migrations quietly break.

If you don’t surface these dependencies early, they show up later as missing functionality or unexpected gaps during testing.

• List every active extension and check if Shopify has equivalent functionality.
• Document all custom checkout, pricing, and tax logic.
• Map every integration (ERP, CRM, 3PL, email, loyalty, support).
• Identify high-traffic URL patterns for redirect planning.
• Audit data quality- check for duplicates, orphaned records, malformed SKUs.

This isn’t just about choosing Shopify Plus or the standard plan. It’s about defining how your business will operate: store structure, international setup, pricing logic, and workflows. These choices directly affect your team’s day-to-day operations and the success of your Magento-to-Shopify migration.

• Define your Shopify plan based on feature and scale requirements.
• Decide on store structure (single, multi-store, or markets).
• Map your product taxonomy to collections and metafields.
• Finalize your theme or build approach before migration begins.

Migration isn’t a one-time activity; it’s a controlled process and a key part of your Magento to Shopify migration steps.

Moving everything at once often hides data issues until late-stage testing. A staged approach allows you to validate each layer before progressing, reducing risk and rework.

• Migrate products, variants, images, and metafields first.
• Migrate customer records with controlled account activation.
• Import historical orders for reference (not operations).
• Migrate content with URL structure preserved.
• Validate all data against Magento before moving forward.

Magento often relies on custom logic and extensions. In Shopify, every feature needs to be evaluated to determine whether it can be handled natively, via apps, or requires custom development. These decisions define your Magento-to-Shopify migration process and its long-term complexity.

• Replace Magento extensions with Shopify-native features( if possible).
• Use apps selectively to avoid unnecessary stack complexity.
• Rebuild custom logic using Shopify Functions or custom development.
• Recreate workflows (discounting, fulfillment routing, notifications).
• Rebuild loyalty, rewards, and subscription payments.

Integration failures are one of the biggest reasons Shopify migrations break after launch, not design or performance, but disconnected systems. ERP, 3PL, and marketing integrations must be tested deliberately, not assumed to work.

• Reconnect ERP with verified field mapping and sync validation
• Test 3PL flows (order routing, fulfillment updates, returns)
• Reconfigure email, SMS, and automation triggers
• Validate all webhook endpoints under real conditions.

SEO preservation during migration is primarily a continuity issue, not a content issue. This is a critical part of your checklist, especially if you want to migrate a Magento store to Shopify without losing SEO.

Shopify uses a different URL structure than Magento, which means your product, category, and content URLs will change. Without proper redirects, you risk losing traffic tied to those pages.

• Export all indexed URLs before migration
• Build a complete 301 redirect map.
• Preserve metadata (titles, descriptions, canonical tags)
• Submit the updated sitemap after go-live.
• Monitor performance (including Core Web Vitals)

You might test the storefront, but what really matters is how your business runs after launch. This is where most migration issues show up.

• Run end-to-end order scenarios (all fulfillment types)
• Test all payment methods (including BNPL)
• Validate returns, refunds, and exchanges.
• Confirm inventory sync across systems.
• Test customer account flows (registration, login, reset)

Going live is where your planning meets reality. Without proper coordination, even a solid migration can break under pressure. The goal is to migrate from Magento to Shopify without downtime, or at least keep it under two hours with a tested rollback plan ready if anything fails.

• Define your maintenance window.
• Assign a go/no-go owner with rollback criteria
• Brief your support teams on expected issues.
• Notify your customers in advance.
• Monitor performance closely after launch.

The first few days after go-live are when most issues in the Magento to Shopify migration process surface. Close monitoring helps you stabilize the store quickly after a transition.

• Track all key metrics (traffic, orders, errors)
• Watch integrations and order flows closely.
• Respond quickly to any anomalies.

The checklist tells you what to do. We make sure it actually gets done, without your revenue, operations, or SEO taking a hit along the way.

This is the category that determines whether your Magento-to-Shopify migration takes six weeks or six months. Some things simply cannot carry over; they need to be rebuilt to work with Shopify’s actual architecture.

Moving from Magento to Shopify is not an upgrade you install; it’s an operational redesign that happens to include a platform change. The teams that do it well spend as much time on operations readiness as they do on development. They test orders, not just pages. And they define what “ready" looks like before they start building, not the week before go-live.

Shopify won’t automatically make your business faster or more profitable. Your execution determines that. What Shopify does offer is a more maintainable, scalable foundation, but only if the migration is treated with the seriousness it deserves.

The checklist above gives you a starting point for your Magento to Shopify migration steps. The harder work lies in the decisions around it: what to migrate and how to keep the business running while everything is in motion.

At Digital Radium, our Magento-to-Shopify migration service is built around these exact decisions. We’ve worked through enough of these transitions to know where teams typically lose momentum, and how to keep things on track.
