How to Migrate Your Website to Shopify: A Step-by-Step Guide for 2026

More than 6.9 million merchants now run their stores on Shopify, according to website-technology tracker BuiltWith, making it the platform most businesses land on when they outgrow WordPress, WooCommerce, Wix, or a legacy custom build. If you are reading this, you have likely already decided Shopify is the right move. The harder question is how to get your existing site there without losing the search rankings, customer data, and order history you have spent years building.

This guide walks through the full migration process in order, flags the step most guides skip, and shows what actually breaks when businesses handle a migration without a plan.

Why Businesses Migrate to Shopify

Most migrations are triggered by one of a few recurring problems: the current platform cannot handle traffic or catalog growth without expensive infrastructure work, the business needs a unified point-of-sale that actually talks to the online store, or the existing site depends on a patchwork of plugins that has become fragile and expensive to maintain. Shopify addresses all three directly. It is built specifically for retail, which means pricing pages, product catalogs, and checkout are optimized for conversion rather than adapted from a general-purpose content management system.

The practical benefits show up quickly after migration. Shopify’s hosted infrastructure removes the need to manage servers, security patches, or uptime monitoring, work that previously fell on internal IT or an agency retainer. Shopify POS gives physical and online sales a single source of truth for inventory, so a sale on the shop floor updates online stock in real time instead of running two disconnected systems. And the Shopify App Store, with more than 13,000 apps as of 2026, means most new functionality is a configuration task rather than a custom development project, at least until a business’s requirements get specific enough to need custom work.

None of that value is realized, though, if the migration itself damages the search visibility and customer relationships the business already has. That is the part this guide focuses on.

Consideration	Typical Legacy Setup	Shopify
Hosting and uptime	Self-managed or agency-managed servers, patching is your responsibility	Fully hosted, uptime and security patching handled by Shopify
In-store and online inventory	Usually two separate systems requiring manual reconciliation	Shopify POS syncs inventory in real time across channels
Adding new functionality	Custom development for most non-trivial features	13,000+ apps cover most standard needs, custom development reserved for specific requirements
Checkout optimization	Depends entirely on what the platform or plugins support	Built for conversion, with Checkout Extensibility available on Plus
Scaling for traffic spikes	Requires infrastructure planning ahead of high-traffic events	Handled by Shopify’s infrastructure automatically

The Real Risk in a Shopify Migration Isn’t the Move, It’s What Happens to Your Rankings

A 2024 Search Engine Journal study of 892 domain and platform migrations found the average recovery time for lost organic traffic was 523 days, and 17 percent of the sites studied never recovered their pre-migration traffic at all. Only about one in ten migrations end with better rankings than before. The other nine either hold flat at best or lose real ground, and the loss is rarely a clean, one-time drop. It tends to arrive quietly: organic sessions soften over several weeks, long-tail keywords stop ranking one at a time, and Search Console impressions trend downward without any single metric looking alarming enough to trigger an investigation until real revenue is already gone.

The severity tracks almost entirely with how the migration was executed, not with the platform change itself. A clean move, where every old URL maps to a specific new one, typically holds losses to 10 to 20 percent in the first month with recovery inside a few weeks. A standard move with some gaps in redirect coverage commonly lands in the 20 to 40 percent range. A migration with no redirect plan at all, where old URLs simply return a 404 and the business waits for Google to figure out the new structure on its own, has been documented losing 60 to 80 percent of organic traffic, occasionally more.

The businesses that avoid the worst outcomes treat SEO as a required migration step, sequenced alongside data migration and store setup, not something to circle back to after the store is live and functional.

Step-by-Step: How to Migrate Your Website to Shopify

The order below matters. Skipping ahead, especially on the data migration order or the SEO step, is the most common cause of the problems covered above and below.

Step 1: Choose the Right Shopify Plan

Basic and Standard Shopify plans cover most small and mid-sized stores. Shopify Plus is built for high-volume merchants, roughly 44,000 stores worldwide use it, and it unlocks Checkout Extensibility, higher API rate limits, and multi-store management that a growing catalog or multi-brand business will eventually need. If your current site processes high order volume, has complex B2B pricing, or runs multiple storefronts, evaluate Plus before you migrate rather than after, since moving plans post-migration means redoing parts of the setup, including re-testing checkout customizations that behave differently on each tier.

Step 2: Audit and Map Your Existing Data

Before moving anything, list what exists on your current platform: products and variants, customer accounts and their order history, active discount codes, blog content, and any custom fields your current system uses that Shopify does not have a native equivalent for. This is also the point to pull a full list of every indexed URL on your current site, from Search Console or a crawler, since that list becomes the input for the redirect map in Step 4. This audit becomes your migration checklist and the reference point for catching anything that fails to transfer in the next step.

Step 3: Migrate Data in the Correct Order

Shopify’s own migration guidance is specific on sequencing: products first, then customers, then historical orders. Importing in this order lets Shopify correctly link each historical order to the right customer and product record, which preserves full purchase history instead of leaving orders as orphaned records with no connection to a customer profile. Most migrations use one of three methods. A dedicated migration app, Matrixify and LitExtension are the most commonly used for moves into Shopify, handles the bulk of standard data through a guided interface and works well for catalogs in the low thousands of SKUs. Manual CSV export and import suits smaller catalogs, generally under a few hundred products, where the extra control is worth the manual effort. A custom-built migration script becomes necessary when the source platform has no clean export path, has heavily customized data structures, or when order history needs to be preserved in a way the standard tools do not support. The right method depends on catalog size and how much of your data lives in non-standard fields, and it is common for a single migration to use more than one method for different data types.

Step 4: Preserve Your SEO Before You Preserve Anything Else

This is the step most do-it-yourself migrations skip, and it is the direct cause of the traffic loss statistics covered earlier. Four things need to happen before launch, not after. First, map every old URL to its new Shopify equivalent with 301 redirects, covering every page type: products, collections, blog posts, and any custom landing pages. Second, carry over meta titles and meta descriptions rather than accepting Shopify’s auto-generated defaults, which are functional but rarely match the search intent your existing rankings were built around. Third, set canonical tags correctly on any page where Shopify’s URL structure creates duplicate-content risk, most commonly on collection pages with multiple sort or filter parameters. Fourth, prepare an updated XML sitemap to submit to Search Console the day you go live, so Google discovers the new URL structure immediately instead of waiting for organic re-crawling. A clean, well-mapped migration with all four of these in place typically holds traffic loss to 10 to 20 percent in the first month, with recovery inside a few weeks. Skipping redirect mapping is the single biggest predictor of the 40 to 60 percent traffic drops seen in poorly executed migrations.

Step 5: Set Up Your Store: Theme, Payments, Shipping, and Taxes

With data and SEO handled, configure the storefront itself. Choose and customize a theme that matches your current brand rather than starting from a generic default, since a jarring visual change on top of a URL change compounds customer confusion and can itself depress conversion during the transition period. Connect payment gateways, set shipping rates and zones, and configure tax settings for every region you sell into. Shopify supports region-specific tax rates out of the box, but custom tax rules for specific product categories, common in regulated categories like supplements or alcohol, usually need manual configuration or a dedicated tax app.

Step 6: Test Everything Before You Flip the Switch

Place real test orders through the full checkout flow, on both desktop and mobile, using every payment method you offer. Verify that redirects actually resolve to the correct new pages rather than throwing 404s, a spot check of ten to twenty percent of your redirect map catches most mapping errors before they become a live problem. Check that customer accounts can log in and see their historical order data. This is also the point to fix any data that imported incorrectly, product descriptions, pricing, or images that did not map cleanly from the old platform, since these are far cheaper to fix before launch than after.

Step 7: Go Live and Monitor Closely for the First 30 Days

Switch your domain’s DNS to point to Shopify, set the store to live, and immediately submit your sitemap in Google Search Console. Monitor organic traffic, keyword rankings, and crawl errors daily for the first two weeks, then at least weekly through day thirty. Some fluctuation is normal as search engines re-crawl and re-index the new URLs, but a sustained drop of more than 20 to 30 percent, or a spike in crawl errors, signals a redirect or indexing problem that needs immediate attention rather than a wait-and-see approach.

Data Migration Methods Compared

The three approaches referenced in Step 3 each fit a different situation. Choosing the wrong one is a common source of mid-migration delays, usually discovered when a catalog turns out to be too large for a manual process, or too customized for a standard migration app to handle cleanly.

Method	Best For	Limitations
Migration app (Matrixify, LitExtension)	Catalogs up to a few thousand SKUs with mostly standard fields	Custom or non-standard data fields often need manual mapping before import
Manual CSV export and import	Small catalogs, generally under a few hundred products	Time-intensive at scale, higher risk of manual entry errors
Custom migration script	Complex data structures, order history preservation, no clean export path	Requires developer time, longest lead time of the three methods

Platform-Specific Notes

The general process above applies regardless of where you are migrating from, but a few details differ by source platform.

• From WordPress or WooCommerce: Product data typically exports cleanly through WooCommerce’s built-in exporter or the WP All Export plugin. The bigger risk is usually blog content and any custom post types, which need a separate migration path since they are not standard e-commerce fields.
• From Wix or Squarespace: Domain transfer can take up to seven days to fully propagate, plan the DNS cutover around this rather than assuming it completes instantly. Theme customizations rarely transfer in any recognizable form and are effectively rebuilt from scratch on Shopify.
• From Magento or a custom-built platform: These typically have the most non-standard data structures and the highest likelihood of needing a custom migration script rather than an off-the-shelf app. Budget the data audit accordingly, since discovering custom fields mid-migration is the most common cause of schedule slips on these moves.

A Realistic Migration Timeline

Timelines vary with catalog size and customization, but the phase breakdown below reflects a typical mid-sized migration, roughly 500 to 2,000 SKUs with a handful of third-party integrations to replicate.

Phase	Typical Duration	What Happens
Audit and planning	1 to 2 weeks	Data audit, URL inventory, redirect map drafted, plan selected
Data migration	1 to 2 weeks	Products, customers, and orders imported in sequence, data validated
Store setup	1 to 2 weeks	Theme, payments, shipping, taxes, and any custom app work configured
Testing and QA	3 to 5 days	Full checkout testing, redirect spot checks, data accuracy review
Go live and monitoring	30 days	Cutover, sitemap resubmission, daily monitoring tapering to weekly

What Doesn’t Transfer Automatically

Even with a migration app handling the bulk of the work, several data types commonly require manual intervention or a workaround. Confirming these before migration day prevents last-minute surprises that push back a launch date.

Data Type	Transfers Automatically?	What to Do
Products, images, prices	Yes, via CSV or migration app	Standard process, verify variants and images after import
Customer accounts	Partially	Customers typically need to reset their password on first login
Order history	Not on standard plans	Requires Shopify Plus or a developer API integration to fully preserve
Product reviews	No	Export from the old platform, re-import through a reviews app like Judge.me or Loox
Subscriptions	No	Requires manual re-onboarding through a subscriptions app such as Recharge or Skio
Custom plugin data	No	Needs developer extraction, this is the most common source of scope surprises

Common Mistakes That Turn a Migration Into a Traffic Loss Event

• Redirecting everything to the homepage instead of the matching page. This is technically a redirect, but Google treats it as a soft 404 for every page that lost its specific destination, which erases the ranking value of each individual URL rather than transferring it.
• Changing URL structure and content at the same time. Rewriting product descriptions in the same window as the URL change makes it impossible to tell whether a ranking drop came from the platform move or the content change, and it doubles the number of variables you would need to unwind if something goes wrong.
• Launching without a sitemap resubmission. Google eventually finds a new sitemap on its own, but resubmitting immediately at launch shortens the re-indexing window from weeks to days, which matters most for the pages carrying the bulk of your existing organic traffic.
• Skipping the redirect spot check. Migration apps and manual redirect maps both produce occasional errors at scale, a five to ten percent spot check before launch catches most of them while they are still cheap to fix, rather than after launch when every broken redirect is actively losing visitors.
• Treating the migration as purely a technical project. Marketing, customer support, and whoever owns paid acquisition all need to know the launch date, since paid campaigns pointing at old URLs and support scripts referencing the old interface both break the moment the new store goes live.
• Not communicating the change to existing customers. Customers who land on a suddenly unfamiliar site, especially one requiring a password reset, are more likely to abandon a purchase than to troubleshoot. A short email explaining the change ahead of launch reduces this friction meaningfully.

How to Evaluate a Shopify Migration Partner

If you decide to bring in outside help, four questions separate a partner who will protect your rankings from one who will simply get the store functional and leave the SEO risk for you to discover later.

• Do they build a redirect map before touching the store? A redirect plan should exist as a reviewable document before any data migration begins, not as an afterthought handled during testing.
• Can they show a past migration’s traffic recovery, not just the launch? A successful launch and a successful migration are different things, ask to see organic traffic data from thirty and sixty days after a previous client’s go-live date.
• Do they handle order history and custom data, or only the standard fields? Many migration vendors handle products and customers well but treat order history, custom fields, and subscription data as out of scope unless asked directly.
• Who owns the sitemap resubmission and post-launch monitoring? This should be an explicit deliverable with a defined monitoring window, not an assumption that either side will handle it.

Special Considerations for Multi-Region or Multi-Language Stores

Businesses selling into multiple markets, a common pattern for companies serving both Western and Japanese retail, need one additional layer of planning that single-market migrations do not: hreflang tags. These tell Google which language and regional version of a page to show a given searcher, and they need to be rebuilt correctly on the new Shopify URLs, not simply carried over from the old site’s structure, since URL patterns for language and market variants often change during a platform move. Getting this wrong does not just cost individual page rankings, it can cause Google to show the wrong regional version to searchers entirely, which is a harder problem to diagnose after the fact than a straightforward broken redirect. Stores using Shopify Markets to manage multiple regions from a single store should map hreflang configuration as part of Step 4, alongside the standard redirect and metadata work, not as a separate follow-up task.

What to Watch in the 90 Days After Launch

The first thirty days catch redirect and indexing problems. The next sixty matter for a different reason: this is the window where you find out whether the migration actually held. Compare organic traffic, conversion rate, and average order value against the same period last year, not against the weeks immediately before migration, since pre-migration weeks are often not representative of normal performance. Watch Search Console’s coverage report for pages that show as indexed but not ranking, a common sign that a redirect resolved technically but lost the ranking signal Google previously associated with that URL. If organic traffic has not returned to within 10 percent of baseline by day sixty, that is the point to audit the redirect map again rather than assuming the dip will resolve on its own.

Should You Migrate Yourself or Bring in Professional Help?

A small catalog with a handful of products and no custom integrations is realistic to migrate yourself over a weekend using Shopify’s built-in import tools. The calculation changes once your store has custom fields, third-party integrations, a large product catalog, or meaningful organic search traffic you cannot afford to lose. At that point, the redirect mapping and data validation work alone can take longer than the actual data transfer, and mistakes are expensive to unwind after launch, both in lost traffic and in the time spent diagnosing what went wrong after the fact rather than preventing it beforehand.

Signs it is worth bringing in a development team rather than handling the migration internally:

• Your catalog has custom fields or product relationships that do not map cleanly to Shopify’s standard structure
• You rely on third-party integrations, ERP, CRM, or a custom loyalty system, that need to keep working after launch
• Organic search drives a meaningful share of revenue and a 20 percent traffic dip would materially affect the business
• You need to preserve full order history, which requires API-level work beyond what standard import tools support
• Your team does not have someone who can own redirect mapping and post-launch SEO monitoring as a defined responsibility

SupremeTech’s Shopify development services handle the full migration process end to end, including data migration and integration, custom app development for anything Shopify does not support natively, and store setup and testing before launch. One example: the team’s offline-to-online commerce work on Shopify Plus involved exactly this kind of platform transition, moving established retail operations onto Shopify without disrupting the customer relationships and purchase history already in place.

Budgeting for a Shopify Migration

Three factors drive most of the cost variance between migrations: catalog size and complexity, the number of third-party integrations that need to be replicated rather than simply reconnected, and whether full order history preservation is a requirement. A straightforward migration, a few hundred SKUs, standard fields, no order history requirement, is realistic as a fixed-scope project. A migration involving custom data structures, multiple integrations, or order history preservation is harder to fix-price accurately upfront and is usually scoped after the data audit in Step 2 reveals exactly what needs custom handling. Budgeting time for that audit before requesting quotes tends to produce more accurate numbers than quoting from a high-level description of the store alone.

It is also worth budgeting for the thirty to ninety day monitoring window as part of the project, not as a separate future task. A migration that looks complete at launch but has no owner for the follow-up monitoring period is the most common way a fixable redirect gap turns into a permanent traffic loss.

Pre-Launch Checklist

Before switching DNS and setting the store live, confirm each of the following. Most migration problems trace back to one of these being skipped or only partially completed rather than to anything exotic.

• Every indexed URL from the old site has a mapped 301 redirect, spot-checked at a five to ten percent sample
• Meta titles and descriptions are carried over or intentionally rewritten, not left as Shopify’s defaults
• Canonical tags are set correctly on any page type with duplicate-content risk, especially filtered collection pages
• An updated XML sitemap is ready to submit to Search Console the moment the store goes live
• Products, customers, and orders have been imported in that order and spot-checked for accuracy
• Payment methods, shipping rates, and tax settings have been tested with real transactions, not just configured
• Customer accounts can log in, and password reset communication is prepared if accounts require a reset
• A monitoring owner and schedule are assigned for the first thirty to ninety days after launch

A migration that clears every item on this list before launch is the difference between the 10 to 20 percent temporary dip that recovers in weeks and the 40 to 60 percent drop that takes months, or longer, to undo.
