Migrating your store to Shopify is one of the highest-stakes decisions you will make as a merchant. If you done right, it is invisible to customers and your SEO holds. Or done wrong, you lose 20 to 40 percent of organic traffic in the first 30 days and spend the next three months fixing problems that should have never existed.
This guide covers the full migration process: what to move, how to move it, what the honest costs and timelines look like, and the specific traps that catch WooCommerce, Magento and BigCommerce merchants off guard. By the end, you will know exactly what a Shopify migration involves and whether you need an agency to run it.
The Short Version
If you are looking for the bottom line before diving into the detail, here it is.
Shopify migration is right for you if your current platform is costing you more in maintenance, plugins, and developer time than it would cost to move. Most merchants who wait too long end up migrating under pressure, which is the worst possible time.
DIY migration works if your store has fewer than 500 SKUs, no complex integrations, and a simple theme. You can use Shopify's free built-in Store Importer (available in your Shopify admin under Apps) and finish in a few days.
Hire an agency if your store has more than 1,000 SKUs, custom integrations (ERP, 3PL, subscription billing), a bespoke checkout, or significant SEO traffic you cannot afford to lose.
For everything else, keep reading.
What Is Shopify Migration?
Shopify migration is the process of moving your online store from another e-commerce platform to Shopify. That includes your product catalog, customer records, order history, content pages, and all the integrations that keep your store running.
It is not a copy-paste operation. Your old platform's URL structure, theme architecture, app ecosystem, and data schema are different from Shopify's. A migration done well maps those differences carefully before a single file is moved.
The platforms most commonly migrated to Shopify in 2026 are WooCommerce, Magento (Adobe Commerce), and BigCommerce. Each one has a different complexity profile and a different set of things that go wrong.
What You Can Migrate to Shopify
Before you plan anything, you need to know what transfers cleanly and what requires rebuilding.
What migrates cleanly with the right tools:
- Products (titles, descriptions, SKUs, prices, inventory levels, images)
- Product variants and options
- Customer accounts and addresses
- Order history
- Blog posts and content pages
- Collections and categories
- Meta titles and meta descriptions
- Discount codes
What requires rebuilding or manual work:
- Your theme and storefront design
- Custom checkout flows
- Third-party app integrations (ERP, 3PL, subscription billing, loyalty programs)
- Custom business logic built into plugins or extensions
- URL structure and 301 redirect mapping
- Payment gateway configurations
The redirect mapping and theme rebuild are where most migrations go over budget and over schedule. Neither is optional. Both take longer than merchants expect.
WooCommerce to Shopify Migration
WooCommerce is the most common starting point for merchants moving to Shopify. As of early 2026, over 9,000 WooCommerce stores switched to Shopify in a single 90-day period, making it the highest-volume migration path on the platform.
Why merchants leave WooCommerce
The honest reason most WooCommerce merchants migrate is what industry practitioners call the WordPress tax. You pay for managed hosting, a security plugin, a backup plugin, a caching layer, a page builder, and a developer on retainer for when things break. None of those costs appear on your "WooCommerce is free" spreadsheet.
By the time a WooCommerce store is running serious volume, it is typically carrying 30 to 60 active plugins. Auditing which of those translate to Shopify apps, which become unnecessary, and which need custom Liquid development is week-one work on every migration.
The WooCommerce-specific traps
Plugin data does not transfer. Anything built into a custom WordPress plugin stays in WooCommerce unless you pay a developer to extract it. Membership data, custom user fields, loyalty points balances, and anything in a custom plugin table are case-by-case decisions.
WooCommerce Subscriptions require specialized handling. Payment token portability between processors is not automatic. If your store runs recurring billing, plan for a re-authorization flow with your customer base after migration.
SEO redirects are non-negotiable. WooCommerce and Shopify use different URL structures. Products on WooCommerce live at /product/[slug]. On Shopify they live at /products/[slug]. Every URL that changed needs a 301 redirect. Skip this step and you lose 20 to 40 percent of organic traffic in the first 30 days.
WooCommerce migration timeline
| Store size | Timeline |
|---|---|
| Under 500 SKUs, simple theme | 2 to 4 weeks |
| 500 to 5,000 SKUs, custom theme | 4 to 8 weeks |
| 5,000+ SKUs, subscriptions, ERP | 10 to 16 weeks |
Magento to Shopify Migration
Magento is the most complex migration source of the three. Merchants running Magento 2 or Adobe Commerce typically have custom ERP middleware, complex B2B pricing rules, multi-store setups, and bespoke checkout extensions. None of that transfers automatically.
Why merchants leave Magento
Adobe Commerce licensing costs have risen steadily over the last three years. Magento 1 reached end-of-life in 2020, leaving stores on it with no security patch path and an increasingly thin pool of developers willing to work on the platform. The operational cost of staying on Magento continues to climb while Shopify's feature set continues to close the gap.
The Magento-specific traps
EAV architecture does not map to Shopify's data model. Magento uses an Entity-Attribute-Value database structure for product data. Shopify uses metafields. Treating a Magento-to-Shopify migration as a CSV export problem is the most common mistake agencies make. It is an architecture problem. Getting this mapping wrong means re-doing the migration.
The URL rewrite table is easy to forget. Magento generates URL rewrites for every product, category, and CMS page. Exporting and mapping that table to Shopify 301 redirects is mandatory for SEO preservation.
Multi-store setups need a strategy before migration begins. Magento supports multiple storefronts from one admin. Shopify handles this through Shopify Markets or separate Shopify stores. Deciding which approach fits your business before migration day saves significant rework.
Custom B2B pricing. Magento's customer group pricing does not have a direct Shopify equivalent below Shopify Plus. If you run B2B with tiered pricing, you need Shopify Plus and its B2B Catalogs feature, or a third-party B2B app.
Magento migration cost range
| Migration scope | Estimated cost |
|---|---|
| Simple Magento 2 store, no B2B | $15,000 to $40,000 |
| Magento with ERP integration | $40,000 to $100,000 |
| Multi-store, B2B, full custom checkout | $100,000 to $250,000+ |
These are agency-led estimates. Self-service migrations of Magento stores at any complexity level above basic are not recommended.
BigCommerce to Shopify Migration
BigCommerce migrations have one friction point that catches merchants off guard: variant limits.
BigCommerce supports up to 600 variants per product natively. Shopify limits products to 100 variants and 3 option types. High-variant catalogs like apparel, configurable products, anything with size, color, and width options need restructuring before migration or a third-party variant app after it.
The theme rebuild also moves from BigCommerce's Handlebars templating to Shopify's Liquid. This is a full rebuild, not a conversion. Budget it as such.
The 7-Step Shopify Migration Process
Regardless of which platform you are migrating from, the process follows the same sequence. Skipping steps or reordering them is where migrations go wrong.
Step 1: Audit your existing store
Before moving anything, document what you have. This means a complete inventory of all products, variants, collections, customer records, orders, content pages, active integrations, and custom functionality.
The audit also includes your SEO baseline. Export your current keyword rankings, top-performing URLs, and backlink profile before migration begins. This is the benchmark you will measure against after launch.
Do not skip the plugin or extension audit. Document every integration, who owns it, what data it holds, and what the Shopify equivalent is.
Step 2: Set up your Shopify store
Create your Shopify store before any data moves. Configure your basic settings: currency, tax rules, shipping zones, and payment gateways. Choose a theme or begin the custom theme build.
Do not wait until data migration is complete to start the theme. Theme development runs in parallel with data migration on every well-run project.
If you are targeting Shopify Plus, this is also when you work through the Shopify Plus launch checklist and configure Checkout Extensibility, B2B Catalogs, and Flows.
Step 3: Export your data
Export your full data set from your existing platform. Products, customers, orders, and content.
Most platforms support CSV export. WooCommerce and Magento also support API-based exports, which are more reliable for large catalogs because they preserve data types and handle encoding consistently.
A few things that are easy to miss during export: downloadable product files, custom product fields, review data, and gift card balances. Add these to your export checklist explicitly.
Step 4: Map and import your data
This step requires the most attention. Data from your old platform does not map one-to-one to Shopify's data structure. Category trees become collections. Product attributes become metafields. Customer groups become Shopify customer segments or B2B Catalogs.
Shopify's built-in Store Importer (free, accessible in your Shopify admin) handles basic WooCommerce and BigCommerce imports. For Magento or large complex catalogs, purpose-built migration tools or a custom import script produce more reliable results.
Import into a test environment first. Validate product counts, variant integrity, image rendering, and customer record completeness before touching your live data.
Step 5: Build your 301 redirect map
Every URL that changed between your old platform and Shopify needs a 301 redirect. This includes product pages, collection pages, blog posts, and any CMS pages.
Build the redirect map as a spreadsheet: old URL, new URL, HTTP status. Import it into Shopify before go-live using the URL Redirects section in the admin, or use a redirect app for large maps above a few hundred redirects.
Missing redirects are the single most common cause of post-migration SEO traffic loss. This step is not optional and cannot be done after launch.
Step 6: Test everything before launch
Do not go live on a deadline without completing a full QA pass. The test should cover:
- Product pages: titles, descriptions, images, variants, pricing, inventory
- Cart and checkout: add to cart, discount codes, shipping rates, payment processing
- Customer accounts: login, order history, address management
- Search functionality
- Navigation and collections
- Blog and content pages
- Mobile rendering on iOS and Android
- Speed: run Core Web Vitals on key pages before and after migration
Place a real test order. Confirm the order confirmation email, fulfillment triggers, and inventory decrement all work correctly.
Step 7: Launch and monitor
Cut over your domain only when testing is complete. Point your domain DNS to Shopify's servers. Confirm SSL is active. Submit your updated sitemap to Google Search Console.
Monitor for 48 to 72 hours post-launch: 404 errors in Search Console, redirect chains, crawl errors, and any spike in customer support contacts about broken pages or checkout issues.
A post-launch monitoring plan is not optional. Every migration surfaces at least a few issues after go-live. The question is whether you catch them in hours or weeks.
Shopify Migration Cost: What to Actually Budget
The number on any agency's website is not the number you pay. Migration cost depends on catalog size, custom integrations, theme complexity, and how much legacy data you bring with you.
| Migration type | Who it is for | Estimated cost |
|---|---|---|
| DIY using Shopify Store Importer | Small stores, under 500 SKUs, simple data | $0 to $500 |
| Automated migration tool (LitExtension, Cart2Cart) | Mid-size stores, limited custom requirements | $500 to $2,000 |
| Agency-led migration | Custom themes, integrations, SEO-critical stores | $5,000 to $25,000+ |
| Enterprise migration (Shopify Plus) | Multi-store, ERP, B2B, complex checkout | $50,000 to $250,000+ |
The costs above cover data migration and basic store setup. They do not include:
- Custom theme design and development (add $5,000 to $30,000+)
- App replacement and configuration (varies per integration)
- Post-launch SEO monitoring and remediation
- Ongoing retainer for issues that surface in weeks 2 to 6
The most common budget mistake is treating migration cost and store build cost as the same number. They are not. Migration moves your data. A store build makes it ready to sell.
Shopify Migration Timeline: What to Expect
| Store type | Realistic timeline |
|---|---|
| Small store, DIY, under 500 SKUs | 1 to 3 weeks |
| Mid-market, agency-led, custom theme | 4 to 8 weeks |
| Large store with ERP integration | 10 to 16 weeks |
| Enterprise Shopify Plus migration | 12 to 24 weeks |
The timeline drivers that most merchants underestimate are the extension and plugin audit, custom theme development, and QA. Data migration itself is often the fastest part. It is the work around the data that takes time.
The 5 Mistakes That Kill Shopify Migrations
These are the decisions that turn a straightforward migration into a three-month recovery project.
Skipping the redirect map. Every agency that has done migrations at scale has seen this. The merchant or developer prioritizes launch speed, skips redirects, and spends the next two months chasing a 30 percent organic traffic decline in Search Console. Redirects take a day to build. Traffic recovery takes months.
Migrating dirty data. Moving your full product catalog without cleaning it first means bringing over duplicate listings, broken images, outdated descriptions, and incorrect inventory counts. Migration day is also your best chance to audit your catalog. Take it.
Underestimating the theme build. Your current theme does not come with you. Shopify uses Liquid templating. BigCommerce uses Handlebars. WooCommerce uses PHP templates. The design you loved on your old platform needs to be rebuilt in Shopify's theme architecture. Trying to convert it programmatically produces worse results than building it fresh.
Going live before QA is complete. There is always pressure to hit a launch date. The stores that launch before QA is done spend their first month fixing broken checkouts, missing product images, and redirect failures while simultaneously trying to run their business. Do the QA pass. Delay the launch if needed.
Choosing the wrong Shopify plan. Merchants with high variant counts, B2B pricing, or complex checkout customization often start on a standard Shopify plan and discover they need Shopify Plus after the migration is live. Evaluate your plan requirements before migration, not after. Shopify Plus starts at $2,500 per month and is typically worth it above $500,000 in monthly GMV.
DIY vs Hiring a Shopify Migration Agency
Most merchants try to do it themselves first. A portion of them succeed. The rest end up hiring an agency to fix what the DIY attempt broke, which is always more expensive than hiring the agency to begin with.
DIY migration makes sense when:
- Your store has under 500 products
- You have no active subscriptions or complex integrations
- Your current site has minimal SEO traffic at stake
- You are comfortable using Shopify's Store Importer app and doing basic CSV manipulation
- Your theme is a standard template, not something custom
Hire an agency when:
- You have more than 1,000 SKUs or significant variant complexity
- Your store runs subscription billing, a loyalty program, or ERP integration
- You have meaningful organic traffic that would cost you revenue to lose during a botched redirect setup
- Your checkout has custom logic that needs to be replicated in Shopify
- You are migrating from Magento at any complexity level above basic

Shopify Migration SEO: What You Need to Protect
Your search rankings are the most vulnerable asset in a migration. They take months to build and can be damaged in hours by a poorly executed migration.
The things that protect your SEO during a Shopify migration are not complicated. But they require discipline and sequencing.
301 redirect mapping. Already covered above. Non-negotiable.
Preserve meta titles and descriptions. Export them from your current platform before migration. Import them into Shopify's SEO fields for every product, collection, and content page. Do not let Shopify auto-generate them from content.
Maintain your URL structure where possible. If you can match your old platform's URL slugs in Shopify, do it. Fewer redirects mean fewer opportunities for errors.
Submit your sitemap after launch. Go to Google Search Console, remove the old sitemap, and submit the new one. This tells Google to re-crawl your updated URL structure.
Monitor for 404 errors. In the two weeks after launch, check Search Console daily for 404 errors. Each one is a URL that did not get a redirect. Fix them immediately.

My Recommendation
For most merchants making this decision in 2026, the question is not whether to migrate. It is when and how.
If your current platform requires a developer to change a product description, has a checkout that breaks under moderate traffic, or costs more to maintain than Shopify would cost to run, the migration math is clear. Move now, with a plan, rather than later under pressure.
The platform migration itself is straightforward when it is planned properly. The danger is in the parts that get skipped: the redirect map, the plugin audit, the QA pass, the theme build estimation. Every post-migration traffic loss story starts with one of those.
If your migration is straightforward like small catalog, standard integrations, no B2B complexity, use Shopify's Store Importer and move at your own pace.
If your store has any meaningful complexity, a Shopify migration agency saves you far more in time, traffic recovery, and developer cost than the upfront engagement fee.
