The Ultimate Shopify Migration Guide for eCommerce Businesses
Something I've been noticing with almost every Shopify migration I've been part of: the part people worry about least (moving the products over) is usually the easy part. The part people worry about least in advance (what happens to SEO rankings three weeks after launch) is usually where the real damage shows up.
This guide is a working set of notes on what tends to go wrong, what tends to go right, and where a Shopify migration guide should probably spend more time than most do. If you're still in the planning phase, an AI Migration Checklist can also help identify potential migration risks before development begins. Most of what's out there covers the surface steps well enough. Fewer of them get into what actually happens once the store is live.
A quick note on scale, because it matters for how much of this applies to you. Shopify is processing something like $378 billion a year in merchant sales at this point, across more than 2.8 million stores. That's part of why so many merchants coming off Magento, WooCommerce, BigCommerce, and custom builds are migrating to Shopify right now. But the platform's size doesn't tell you much about how your specific migration will go. That depends on:
- How much custom logic your current store is carrying
- How large your catalogue and URL count are
- How carefully the SEO handoff gets managed
- Whether you're migrating with time to spare, or against a deadline
Why merchants tend to move to Shopify
A pattern I keep seeing across client conversations:
-
Cost creep on self-hosted platforms. Hosting, developer time, and plugin licensing add up in ways that don't register as a cost problem until someone actually totals it.
-
A traffic spike that broke the old site. A store that slows or crashes during a sale event tends to move fast on a migration decision after that happens once.
-
The app store. Bundles, wishlists, back in stock alerts, loyalty programs. Functionality that used to need a developer now exists as a purpose built app.
-
AI driven shopping. Orders coming from AI assistants and AI search tools into Shopify stores have grown a lot over the past year. Not the main reason most brands migrate yet, but it's showing up in more planning conversations than a year ago.
Before touching anything: the assessment phase
This is the step that gets skipped most often, and it's usually why a migration runs over budget or over timeline. Before picking a migration method, you want real numbers on:
- SKU and variant count, plus how many customer accounts and historical orders exist
- Every third party tool connected to the store right now (ERP, accounting, email marketing, reviews, loyalty, POS, shipping), each one needs a plan, even if that plan is "we're dropping this"
- Your current SEO footprint, pulled from Search Console before you touch anything. This becomes the backbone of your redirect plan
- Anything custom that isn't standard functionality (custom checkout fields, B2B pricing tiers, subscription logic), these rarely move over automatically
One more thing worth doing here that I didn't emphasize enough before: run an actual crawl of your site with something like Screaming Frog or Sitebulb before you migrate. It catches URLs, title tags, meta descriptions, and page structure you'd otherwise be relying on memory for. Trying to reconstruct this list after the migration is much harder than pulling it beforehand.
If you can't answer roughly how many products, how many customers, and which pages actually drive traffic, it's probably too early to pick a migration method.This applies whether it's a single storefront or a larger effort to migrate a website to Shopify infrastructure across multiple regions at once.
Timing matters more than most guides mention
A pattern I've seen bite people more than once: migrating right before a busy season. If there's any way to plan around it, migrating at least six months ahead of your peak season, or right after it ends, gives the site time to recover before the traffic that actually matters arrives. Migrating two weeks before Black Friday because "we finally found the time" is one of the more avoidable mistakes on this list.
Choosing a Shopify plan
The plan choice matters less than people expect for most small to mid size migrations, but it shapes a few decisions:
- Basic tiers work fine for smaller catalogs and single channel sellers.
- Standard mid tier plans cover most straightforward migrations without issue.
- Advanced or Plus tends to be driven by shipping rule complexity, B2B needs, or checkout customization, not catalog size alone.
- Shopify Plus adoption has been growing quickly among enterprise merchants,if multi currency at scale or a B2B storefront is part of the plan, it's worth having that conversation early rather than hitting limits on a mid tier plan later. We've gone deeper into what that specific move involves in our Shopify Plus migration guide.
What actually needs manual attention, by platform
This is the part most shopify migration fundamentals guides gloss over. "Migrate your data" means something different depending on where you're coming from.
Magento to Shopify. Magento stores tend to carry the most custom logic of the group, which is a big part of why more brands are switching from Magento to Shopify in the first place.
- Custom attributes usually need rebuilding as Shopify metafields
- Multi store setups need reworking, since Shopify handles regions through Shopify Markets rather than separate store instances
- Layered navigation and heavily modified checkouts rarely translate directly
WooCommerce to Shopify. Core product and order data usually moves fairly cleanly.
- Blog content built with a page builder (Elementor, Divi) tends to need manual rebuilding
- Plugin dependent functionality is the real time sink, WooCommerce stores often run fifteen or more plugins, and each one needs either a Shopify app equivalent or a decision to drop it
- SEO plugins specifically (Yoast, RankMath) don't come with you. Whatever schema and metadata they were generating needs a Shopify equivalent (Yoast SEO for Shopify, Smart SEO, or similar) planned in advance
BigCommerce to Shopify. Probably the closest to a like for like move among the major platforms.
- Custom field mapping is usually the main friction point
- B2B catalog rules need extra attention if you're on BigCommerce's B2B edition
Custom-built or legacy platforms. Budget the most QA time here.
- No native connector, so most of this runs through CSV exports or a custom script
- Passwords typically can't move over for security reasons, so customers reset on first login worth flagging in your launch email, since it generates support tickets if it's a surprise
Plan Your Shopify Migration With Confidence
Generate a personalized migration checklist and identify potential SEO and data migration risks before development begins.
Generate Free Checklist →Data migration, practically
| Data Type | Moves Natively? | Practical Approach |
|---|---|---|
| Products (title, price, images, variants) | ✅ Yes, via CSV importer | Native import works well for stores with a few thousand SKUs. |
| Customer accounts | ⚠️ Records yes, passwords no | Import customers via CSV. Customers will reset their password when they log in for the first time. |
| Order history | ❌ Not as live orders | Use Matrixify or a similar migration tool, or keep read-only access to the old platform for historical records. |
| Product reviews | ❌ No | Import reviews using a dedicated review app with SKU matching. |
| Blog content and URLs | ❌ No (manual) | Export content from your previous CMS, rebuild posts in Shopify, and preserve existing URL slugs with redirects where necessary. |
| Subscriptions | ❌ No | Use a subscription platform such as Recharge or Shopify Subscriptions, each with its own migration process. |
| Gift cards and store credit | ⚠️ Partial | Usually requires manual reconciliation. This step is frequently overlooked during migrations. |
On method:
-
Native CSV import: free, fine for straightforward catalogues under a few thousand SKUs
-
Migration apps (Cart2Cart, LitExtension): worth the cost for mid-size catalogues where order history needs to come along
-
Custom API build: needed past roughly 10,000 SKUs, or with unusual data relationships
-
A migration partner: mostly saves time on QA and redirect mapping rather than doing anything a merchant couldn't technically do themselves
The SEO piece, which deserves more attention than it usually gets
I've been testing this across a handful of migrations, and the pattern holds: rankings don't drop because Shopify is worse for SEO. They drop because of a short, repeatable list of mistakes, and this is usually the section a Shopify migration guide either gets right or skips entirely. Once the store is stable, our Shopify SEO checklist is worth working through as a follow-up, since a few of these items overlap with ongoing SEO maintenance beyond just the migration itself.
Build the redirect map first. Pull every indexed URL from Search Console's coverage report, cross-referenced against top organic landing pages, before the migration starts.
| Old URL | New Shopify URL | Redirect Type | Priority |
|---|---|---|---|
/products/blue-widget |
/products/blue-widget |
301 | High |
/category/widgets |
/collections/widgets |
301 | High |
/blog/how-to-choose-a-widget |
/blogs/newsroom/how-to-choose-a-widget |
301 | Medium |
/about-us.html |
/pages/about-us |
301 | Low |
The mistakes that actually cause traffic loss, in roughly the order I see them:
- Missing redirects on category or collection pages and older blog posts. These carry more backlinks than people assume, so missing them hurts more than missing a single product page
- Redirect chains, old URL points to page B, which points to page C. Google has to follow the whole chain, and it bleeds link equity along the way. Point old URLs straight to their final destination
- Using a 302 instead of a 301. A 302 signals "temporary" and doesn't pass ranking value the way a 301 does
- Leaving "noindex" turned on from staging. This is the one that does the most damage fastest, since it tells search engines to deindex the whole site. Double-check robots.txt and the theme's indexing setting before launch, not after
- Losing title tags, meta descriptions, and alt text in the CSV import, since most importers don't carry these over automatically. Budget time to re-enter these for at least your top 50 to 100 pages by traffic
- Shopify's native redirect tool tops out at 10,000 entries. Large catalogs need a bulk redirect app past that point
After launch: add the domain in Search Console, submit the new sitemap, request indexing on priority pages through URL Inspection, and keep the redirects live for at least a year (longer if you can manage it). Then watch Search Console daily for the first couple of weeks. A short dip in impressions during recrawling is normal. A sustained drop in indexed pages or a spike in 404s usually means something in the map got missed.
Protect Your Rankings Before Launch
Review redirects, metadata, indexing, and URL structure before migrating your store to Shopify.
Run Free SEO Audit →A rough way to estimate the size of the risk, borrowed from Shopify's own migration guidance: take the percentage of your traffic that comes from SEO, multiply by the percentage of that traffic that's non-branded, multiply by 15 to 30 percent, and that's roughly the revenue dip you might see over one to six months if things go reasonably well. It's a conservative, prepare-for-the-worst number, not a prediction, but it's a more useful planning figure than "traffic might drop a bit."
Still figuring out how much of this changes as redirect maps run into the thousands of rows. That part seems to need more manual review than smaller migrations do.
Setting up the store itself
- Pick a theme that roughly matches your current navigation depth and product presentation. Free themes aren't automatically slower than paid ones
- Rebuild navigation and megamenus to match, or ideally improve on, the current structure, it affects both how customers move through the store and how internal links pass equity between pages
- Expect functionality to split across separate apps rather than one plugin doing everything (wishlists, bundles, back in stock, loyalty each usually get their own app), worth explaining to a client early so they're not expecting one tool to cover it all
- Configure payments, shipping zones, and tax settings before importing products, since pricing display depends on them
Testing before launch
Roughly in this order, since each layer depends on the one before it:
- Payment methods process a real or sandbox transaction correctly
- Shipping rates calculate correctly for every zone you sell to
- Tax calculates correctly for wherever you have nexus
- Product variants, pricing, and inventory counts match the old platform exactly
- Mobile checkout completes end to end, something like 79% of purchases on Shopify stores happen on mobile checkout, so this isn't optional testing
- At least 50 priority redirects are spot-checked manually
- Site search returns reasonable results
- Order confirmation, shipping, and password reset emails actually send
- Connected apps (reviews, loyalty, subscriptions) behave as expected
- Page speed is equal to or better than the old site

Book a Free Migration Consultation →Launch day
- Point DNS to Shopify using the A record and CNAME Shopify provides
- Confirm SSL is active (usually automatic, but worth checking rather than assuming)
- Activate the redirect map through Shopify's native settings, or a bulk redirect app if the map runs past 10,000 entries (our Shopify launch checklist covers the rest of what's worth confirming on launch day beyond redirects)
- Submit the new sitemap
- Watch server response codes for the first few hours
- Have a rollback plan written down, not just in someone's head, in case DNS needs to revert fast
The first ninety days, which almost nobody talks about
Most guides stop at launch. This is the phase that actually decides whether the migration worked.
-
Week 1: daily Search Console checks for crawl errors and indexing status, daily comparison of conversion rate and checkout completion against your pre-migration baseline
-
Weeks 2 to 4: weekly review of organic traffic by landing page against your pre-migration export, plus a check for orphaned pages that exist but aren't linked from anywhere
- Days 30 to 90: monthly ranking check on your top 20 to 50 keywords. Most pages should be at or close to pre-migration rankings by then. If a page hasn't recovered, it's usually a missed redirect, thinner content than the original, or a backlink still pointing to the old URL
| Store Size | Typical Scope | Rough Timeline |
|---|---|---|
| Small (Under 500 SKUs) | Native product import with a standard Shopify theme setup. | 1 to 3 weeks. Often feasible as a DIY migration. |
| Mid-size (500 to 5,000 SKUs) | Migration app, custom theme development, and app reconfiguration. | 4 to 8 weeks with agency involvement. |
| Large or Enterprise (5,000+ SKUs, B2B, Subscriptions) |
Custom API-based migration with Shopify Plus implementation. |
8 to 16+ weeks, depending on integrations and business complexity. |
These ranges move around a lot by region, agency, and scope. Treat them as a planning reference, not a quote.
Mistakes I keep seeing, and what they actually cost
-
Skipping the redirect map. Lost rankings that can take months to recover, if they recover fully at all
-
No backup of the old platform's data. No fallback if something gets corrupted during import, which happens more often than people expect
-
Not testing tax and shipping before launch. Shows up fast as incorrect checkout totals and cart abandonment
-
Assuming plugin functionality just carries over. Broken features on launch day, subscriptions and loyalty points being the most common casualties
-
Launching without telling customers about the password reset. A wave of support tickets that's mostly avoidable with one email
-
No post-launch monitoring plan. SEO and conversion problems go unnoticed until revenue has already dropped, which is a much harder position to fix from
Most of these overlap with the broader pattern we've seen across launches generally, not just migrations. Worth a look if you want the wider list: 15 reasons Shopify stores fail after launch.
Should you migrate now, or wait
Roughly:
-
Migrate now if the current platform is genuinely limiting growth, plugin and maintenance costs keep climbing, or a redesign or rebrand is already planned
-
Wait if you're within about 60 days of peak season, the SEO footprint hasn't been audited yet, or the bandwidth to properly test the migration isn't there right now

A Shopify migration guide can only get you so far on paper. A Shopify migration itself isn't a weekend project, even when the checklist makes it look like one. The stores that come through it cleanly tend to be the ones that treat the redirect map, the timing, and the 90-day monitoring period as seriously as the actual data move.
This might not apply to every store or every catalogue size, but it's the pattern I keep running into: the migrations that go quietly and well are rarely the ones with the fanciest tooling. They're the ones where someone checked the redirect list twice and didn't schedule the launch two weeks before their biggest sale of the year.
If you're in the middle of planning one of these and want a second look at your redirect map or data structure before launch, that's something worth talking through with a Shopify specialist before you're locked into a launch date.
Frequently Asked Questions About Shopify Migration
How long does a Shopify migration take?
A Shopify migration typically takes 1 to 3 weeks for stores with fewer than 500 products, 4 to 8 weeks for mid-sized stores with custom themes and third-party integrations, and 8 to 16 weeks or longer for enterprise businesses with Shopify Plus, B2B functionality, multiple storefronts, ERP integrations, or custom applications. The biggest factors affecting the timeline are data complexity, custom functionality, SEO migration, testing, and the number of integrations rather than product count alone.
Will I lose my SEO rankings when migrating to Shopify?
A properly planned Shopify migration should not result in permanent SEO losses. Temporary fluctuations in rankings and traffic are common while Google recrawls the new site, but long-term ranking drops are usually caused by missing 301 redirects, changes to URL structure, lost metadata, broken internal links, duplicate content, or indexing issues. Creating a complete redirect map, preserving metadata, submitting the new sitemap, and monitoring Google Search Console after launch significantly reduce SEO risk.
Can customer passwords be migrated to Shopify?
No. Customer passwords cannot be transferred from Magento, WooCommerce, BigCommerce, or most other ecommerce platforms because passwords are encrypted and cannot be exported in a reusable format. Customers will need to create a new password or reset their existing password after the migration. Sending password reset instructions before launch helps reduce support requests and improves the customer experience.
What data can be migrated to Shopify?
Most Shopify migrations include products, collections, customers, historical orders, blog posts, pages, images, product variants, redirects, and SEO metadata. Custom functionality such as subscription logic, loyalty programs, B2B pricing rules, ERP integrations, custom checkout workflows, or proprietary plugins usually requires manual redevelopment or replacement with compatible Shopify apps.
Can order history be migrated to Shopify?
Yes, but with some limitations. Historical orders can usually be imported using migration tools such as Matrixify or custom migration scripts. However, imported orders typically function as historical records rather than fully active Shopify orders. Many businesses also keep read-only access to their previous ecommerce platform for accounting, reporting, warranty claims, and customer support.
What's the biggest risk during a Shopify migration?
The biggest migration risks are incomplete redirect mapping, missing SEO metadata, incorrect product data, incompatible third-party applications, and insufficient testing before launch. Most migration issues are preventable through detailed planning, multiple rounds of quality assurance testing, and continuous monitoring after the new Shopify store goes live.
Can I migrate to Shopify without downtime?
Yes. Most businesses build and test their new Shopify store in a staging environment while the existing store remains live. Once testing is complete, the domain's DNS records are updated to point to Shopify. If the migration has been planned correctly, customer downtime is usually limited to a few minutes during DNS propagation.
Which platforms can migrate to Shopify?
Businesses commonly migrate to Shopify from WooCommerce, Magento, BigCommerce, Adobe Commerce, OpenCart, PrestaShop, Wix, Squarespace, Salesforce Commerce Cloud, Shopware, and custom-built ecommerce platforms. The migration process varies depending on the platform because each stores products, customers, orders, URLs, and custom functionality differently.
Should I use a migration app or hire a Shopify migration expert?
Migration apps work well for straightforward stores with standard product catalogs and minimal custom functionality. Stores with complex SEO requirements, thousands of products, Shopify Plus implementations, ERP integrations, B2B features, subscriptions, or extensive custom development often benefit from working with an experienced Shopify migration partner to reduce technical risks and post-launch issues.
How do I know if my Shopify migration was successful?
A successful Shopify migration means more than transferring products. After launch, verify that all important pages return a 200 status code, 301 redirects work correctly, Google indexes the new URLs, organic traffic begins to recover, orders process successfully, customer accounts function properly, and third-party integrations operate as expected. Monitoring Google Search Console, Google Analytics, and Shopify Analytics for the first 30 to 90 days helps identify and resolve migration issues before they affect revenue.
