How to Migrate from BigCommerce to Shopify (2026 Guide)

Migrating your BigCommerce store to Shopify can be a high-stakes task. Products, customers, URLs, payment settings, tracking pixels, and email integrations all need to move at once so you don’t miss a beat with sales or customers.

But it doesn't have to be chaotic. With the right sequence and a solid cutover plan, a BigCommerce-to-Shopify migration can be a relatively trouble-free process.

This guide gives you a reliable, step-by-step runbook for how to migrate BigCommerce to Shopify. It covers everything from premigration planning through post-launch optimization, with checklists, timelines, and decision frameworks you can act on immediately.

Why migrate from BigCommerce to Shopify in 2026?

Ecommerce replatforming is never a decision taken lightly. It takes time, money, and organizational focus. So why are so many merchants making the move?

The top reasons teams replatform:

• Scaling limits: Traffic spikes cause slowdowns, or the platform can't support expansion into new markets or sales channels without significant custom development.
• Checkout friction: Conversion rates stall because checkout customization options are limited.
• Slow deployment cycles: Simple changes (a new promo, a landing page tweak) take days instead of hours.
• Integration complexity: Connecting third-party tools, enterprise resource planning systems (ERPs), or marketing platforms requires heavy development resources.
• Rising costs without rising capability: Platform fees climb, but the feature set doesn't keep pace.

These are the kinds of pain points that drove brands like Bombas and Staples Canada to replatform.

Bombas, the mission-driven sock brand, was battling site crashes during high-traffic moments. After migrating to Shopify Plus, the brand saved $108,000 a year in platform costs, hit $17.2 million in sales in their first year after replatforming, and achieved 300% year-over-year growth.

Staples Canada, meanwhile, was stuck on a bulky custom platform that could only deploy new promotions once a day—at night, while the site was taken down. After replatforming to Shopify Plus in under 12 months, Staples could run four times as many online promotions per day. The brand set all-time sales records during Black Friday and Cyber Monday, and when the COVID-19 lockdown hit, their site handled 30 consecutive days of Black Friday-level traffic with no performance issues.

The broader market context reinforces why platform reliability matters more than ever. Ecommerce accounted for 16.4% of total US retail sales in Q3 2025, with online sales growing at 5.1% year over year, outpacing total retail growth at 4.1%. When your ecommerce platform is becoming a larger share of your revenue engine every quarter, a platform that can't keep up is actively holding you back.

What makes Shopify migration more compelling in 2026

The case for replatforming continues to grow. Several things have shifted recently that make Shopify a stronger landing spot than it was even two years ago.

• Checkout performance has widened the gap. Shopify's checkout converts up to 36% better than competitors, according to one study by a Big Three management consulting company. For a midsize store doing $5 million in annual revenue, even a few percentage points of checkout conversion improvement translates to hundreds of thousands of dollars in recovered sales.
• Speed of iteration is dramatically faster. Shopify's app ecosystem, theme architecture, and native tools like Shopify Flow for automation and Checkout Extensibility for customization mean teams can ship changes in days rather than months. Merchants aren't waiting on agency backlogs or custom development queues for things like new payment methods or international expansion.
• The integration ecosystem keeps expanding. The Shopify App Store has thousands of apps covering everything from ERP connectors and subscription billing to loyalty programs and advanced analytics. For BigCommerce merchants who've struggled with limited integration options or expensive custom builds, this is a major upgrade in what's possible without heavy development investment.
• Platform investment is accelerating. Shopify invested $1.4 billion in R&D in 2024 and reported full-year revenue growth of 26%. That level of reinvestment means the platform itself keeps getting better, with new features shipping regularly. Merchants benefit from continuous improvement without having to manage upgrades themselves.
• Migration isn’t just data transfer. A BigCommerce to Shopify migration touches SEO, analytics tracking, payment processing, and operational workflows. Plan for all of them, not only the product catalog.

Premigration planning

The difference between a smooth transition and a painful one usually comes down to preparation. This section covers the three planning steps that prevent the most common migration disasters.

1. Choose a migration method

There are three ways to move your BigCommerce store to Shopify: manually, with a migration tool (e.g., Matrixify), or with a specialist partner. The right choice will depend on your catalog size, data complexity, and how much SEO risk you're willing to absorb.

A quick note on Matrixify specifically: It connects directly to the BigCommerce API and can migrate products, custom collections, customers, and URL redirects in one flow. It also generates redirects from old BigCommerce product and collection URLs to their new Shopify equivalents. This can be a significant time-saver. 

That said, order history still needs to be exported from BigCommerce as a CSV file and manually converted to the Matrixify import template. Keep that in mind if preserving full order details in Shopify is important for your business.

For most merchants with a moderate product count and some data complexity, tool-assisted migration hits the right balance of speed and control. If you're running a complex multi-market store with deep ERP integration, a partner is often worth the investment.

2. Inventory the data that must move

Before you export anything, you need a complete picture of what's moving and what needs transformation. You’ll also need to know what Shopify won't import automatically. Surprises here will cause post-launch scrambles.

Use this checklist to audit your current BigCommerce store:

Pre-migration data inventory

• Products, including variants, options, and product descriptions
• SKUs, barcodes, and inventory counts (per location if applicable)
• Categories (these will map to Shopify collections)
• Customer data, including shipping addresses and marketing consent status
• Order history (decide how far back you need)
• Pages and blog content
• Product images and media files
• Reviews, wishlists, and loyalty points (usually migrated via third-party apps)
• URL structure documentation (for redirect mapping)
• Meta titles and meta descriptions
• Custom fields or metafields

There are few things to flag here. For security reasons, customer passwords can’t be migrated from BigCommerce to Shopify. Customers will need to reset their passwords upon their first login to your new Shopify store. Plan proactive communications around this, because it will affect customer accounts.

Reviews, wishlists, and loyalty data usually live in third-party apps on both platforms. Check whether your current app provider supports cross-platform export, or whether you'll need an intermediary tool to move that data.

3. Freeze window and cutover plan

Treat your migration like a software release. Define a content freeze window before your final data export so you're not chasing a moving target. And plan a soft launch behind a password so your team can QA everything before customers see the new site.

Here's a cutover timeline you can adapt:

Cutover timeline (T-7 to T+7 days)

T-7: Set a final content freeze on BigCommerce. No new products, price changes, or page edits from this point.

T-6 to T-5: Run your final data export from BigCommerce. Clean and transform CSVs or run a tool-assisted migration with Matrixify.

T-4 to T-3: Import all your data into Shopify. Validate products, customers, and collections. Upload all redirects.

T-2: Conduct QA. Test checkout flow, payment processing, shipping/tax calculations, discount codes, and email triggers.

T-1: Conduct a final redirect validation. Confirm analytics and tracking tags fire correctly. Run a test transaction end to end.

T-Day (go-live): Update the DNS to point to Shopify. Switch Shopify Payments to live mode. Remove password protection. Submit the new sitemap to Google Search Console.

T+1 to T+3: Monitor for 404 errors, crawl issues, and conversion anomalies. Watch Search Console for indexing problems.

T+7: Run a first-week review. Check organic traffic trends, revenue vs. baseline, and redirect coverage.

Export from BigCommerce

Export products, customers, and orders

BigCommerce provides CSV export functionality for products, customers, and orders through its admin panel. The exports are straightforward to generate, but the output format won't match Shopify's import templates exactly.

Here's where you'll typically need to do cleanup work:

• Product variants and options: BigCommerce structures product options differently from Shopify. You'll need to map these to Shopify's variant format (Option1, Option2, Option3 with corresponding values).
• URL handles: BigCommerce product URLs and Shopify product handles follow different conventions. Plan your handle mapping carefully, because this directly affects your redirects.
• Category-to-collection mapping: BigCommerce categories don't translate one-to-one to Shopify collections. Map each category to either a manual or automated collection in Shopify.
• Image URLs: Product images in your export will reference BigCommerce-hosted URLs. Shopify will attempt to pull these during import, but check that all images transferred correctly afterwards.
• Custom fields: If you're using BigCommerce custom fields, you'll need to map these to Shopify metafields. This usually requires manual CSV editing or a migration tool.

If you're using Matrixify, much of this conversion is handled automatically during the API-based import. The tool converts BigCommerce products into Shopify's format and creates collections and redirects as part of the same process.

Images and CDN URLs: The SEO pitfall most guides skip

Here's a detail that catches some merchants off guard. When you set up 301 redirects for your old BigCommerce URLs, you're redirecting page URLs on your domain. That works well for product and collection pages, as well as blog posts.

But BigCommerce product images are often served from a content delivery network (CDN) that you don't own or control. You can't create 301 redirects for those CDN image URLs, because you don't own that domain.

Reality check: Page URL redirects work. CDN image URL redirects usually don't.

If your BigCommerce images are served from a CDN you don't control, the only viable approach is to re-host all images on Shopify and update every internal reference. Don't plan on redirecting old image URLs.

In practice, what this means is you’ll have to upload all your product images to Shopify (which happens automatically during product import in most cases). Then check that no internal links, blog posts, or custom pages still reference old BigCommerce CDN image URLs. If they do, update them to point to the Shopify-hosted versions.

This is a manual process, but it's essential. Broken images hurt both user experience and SEO.

Import into Shopify

Import products first and validate everything

Products are the foundation of your new Shopify store. Import them first, then validate before bringing in customers or accepting orders. 

The recommended import sequence is:

1. Products (including variants, images, and SEO metadata)
2. Collections (mapped from BigCommerce categories)
3. Pages and blog content
4. Customers (including marketing consent)
5. Orders (optional, depending on your retention needs)

After your product import completes, run through this QA checklist before moving on:

10 things to verify after product import

• Total product count matches expected number
• Variant counts are correct for each product (spot-check at least 10–20 products)
• SKUs are unique and correctly assigned
• Inventory counts are accurate per location
• All product images display correctly (no broken thumbnails)
• Product descriptions render properly (check for broken HTML)
• Prices and compare-at prices are correct
• Meta titles and meta descriptions carried over
• Product URLs (handles) match your redirect mapping plan
• Collections contain the right products

If you're using Matrixify, take advantage of the dry-run option. It generates an Excel file showing exactly how your BigCommerce data will map into Shopify without actually importing anything. Review it carefully, make corrections in the spreadsheet, and then run the real import.

Rebuild key storefront elements

Migration is a chance to simplify your storefront, not replicate old clutter. BigCommerce category structures can accumulate years of decisions that no longer serve the business. Take this opportunity to clean up.

Focus on these areas to make the biggest impact:

Navigation: Map your BigCommerce categories to Shopify collections and menus. Keep your top-level navigation lean. If your old site had 15 items in the main nav, would 7 or 8 serve your customers better? It’s worth considering.

Search and filtering: Shopify's Search & Discovery app (available on the Shopify App Store) handles onsite search and filtering, alongside product recommendations. Set up your filters based on product tags and metafields rather than trying to replicate BigCommerce's exact filter structure.

Mobile-first layout: Choose a Shopify theme that prioritizes mobile user experience (UX). Check that your product and collection pages—and checkout—work well on smaller screens. 

Preserve SEO during the move

For many merchants, SEO preservation is the single highest-stakes element of a BigCommerce-to-Shopify migration. Get this wrong and you can lose months of organic traffic. Get it right and you'll maintain, or even improve, your search visibility.

Map URLs and build 301 redirects

The goal is simple: every important old URL should resolve to its closest new equivalent via a 301 redirect. This tells search engines that the content has permanently moved, and passes link equity to the new URL.

Here's how to map your URLs:

• Product pages: /products/product-name/ ➡️ /products/product-name
• Category pages: /categories/category-name/ ➡️ /collections/collection-name
• Blog posts: /blog/post-title/ ➡️ /blogs/blog-name/post-title
• Misc pages: /about-us/ ➡️ /pages/about-us

Google's site move documentation is the most authoritative reference here. The key principles involve preparing your new site fully before going live, and mapping old-to-new URLs comprehensively. Don't block important pages from crawling, and monitor everything closely after the switch.

Standard Shopify plans support up to 100,000 redirects. Shopify Plus supports up to 20 million. For most BigCommerce migrations, that's more than enough headroom.

If your store has thousands of products, build your redirect mapping in a spreadsheet and use Shopify's bulk redirect import (or a tool like Matrixify, which generates redirects automatically during migration). Prioritize redirects by traffic value: your top revenue-generating pages should be mapped first.

Note: A 301 redirect (permanent redirect) tells search engines the page has moved and to transfer ranking signals to the new URL. A 302 redirect is temporary and doesn't pass link equity. Always use 301s for migration.

Post-launch SEO actions

The first two to four weeks after launch are your main monitoring window. Here's what to focus on:

Post-launch SEO monitoring checklist (first 14 days)

• Submit your new XML sitemap in Google Search Console.
• If you changed domains, add and verify the new property in Search Console.
• Monitor the Coverage/Indexing report daily for the first week.
• Check for 404 errors. Prioritize fixing any that affect high-traffic pages.
• Verify that your top 20 landing pages (by organic traffic) are indexed and ranking.
• Verify that your top 10 revenue pages (by organic revenue) are indexed and ranking.
• Check that canonical tags are correct on all product and collection pages.
• Confirm robots.txt isn't blocking important pages.
• Monitor organic traffic daily against your premigration baseline.
• Check for crawl anomalies or sudden drops in indexed pages.

Some temporary fluctuation in organic traffic is normal after a migration. For smaller sites, recovery usually takes a few weeks. For larger sites with tens of thousands of pages, full recovery can take one to three months. The key is to catch problems early by monitoring your highest-value pages first.

Payments, shipping, taxes, and compliance

These settings directly affect your ability to process revenue. If any of them are wrong at launch, you'll either lose sales or create compliance problems. Keep your setup process crisp and test everything.

Payments: Set up Shopify Payments (or your preferred payment provider) and run at least one test transaction end to end. Confirm that payment capture, refunds, and multi-currency settings all work correctly. If you accept alternative payment methods (e.g., Shop Pay, Apple Pay, PayPal), test each one.

Shipping: Configure your shipping zones and rates to match your current setup. If you use calculated carrier rates, verify that the integration is working. Generate a test shipping label if you use Shopify Shipping.

Taxes: Configure tax settings based on your nexus obligations. Shopify handles basic tax calculations automatically, but make sure to verify rates for your key jurisdictions. Consult your tax advisor for compliance specifics if you’re not sure.

Launch-blocker checklist:If any of these fail, don’t go live.

• Payment gateway processes a test transaction successfully.
• Refund workflow works end to end.
• Shipping rates calculate correctly for all zones.
• Tax rates are accurate for your primary jurisdictions.
• Order confirmation emails send correctly.
• SSL certificate is active and the site loads over HTTPS.
• Checkout page renders correctly on mobile and desktop.

Analytics and tracking continuity

Most migrations don't "lose data" through missing products. They lose it through broken tracking. If your analytics tags don't fire correctly on the new site, you'll have gaps in attribution that take weeks to notice and longer to fix.

Here's what to verify:

Run at least two test transactions and verify each tool's real-time reporting. Don't rely on tag preview modes alone, because they don't always catch checkout-specific issues.

If your digital transformation involves consolidating analytics and marketing tools alongside your platform migration, plan those integrations as part of the same project rather than as a follow-up.

Post-migration optimization

A successful migration gets you to parity with your old site. Post-migration optimization is where you start to see the real returns on your investment.

Stabilize first, then optimize conversion

Resist the urge to start A/B testing on day one. The first 30 days are about confirming that everything works. After that, you can start improving.

Schleich, the German toy manufacturer, shows what's possible post-migration. After migrating to Shopify Plus, the brand improved their checkout abandonment rate by 31% and increased orders by 25%. Those gains came from Shopify's checkout performance and the flexibility to integrate marketing channels quickly after migration.

Italian coffee brand Kimbo took a phased approach. They migrated from Magento to Shopify Plus over about four months, starting with a "showcase store" before enabling full purchasing. Within three months of going live, Kimbo saw an 87% increase in organic qualified leads and a 5.7% increase in organic traffic, with a 1.1% conversion rate that continued climbing. The team used Shopify's Checkout Extensibility to customize their checkout for billing requirements, something that would have taken far longer on their previous platform.

Here's a 30/60/90-day framework for making it work:

Days 0–30: Stabilize

• Fix any remaining redirect gaps or 404 errors.
• Resolve tracking discrepancies.
• Monitor site speed and Core Web Vitals.
• Address customer-reported bugs or UX issues.
• Validate that inventory sync is accurate across all channels.

Days 31–60: Tune

• Refine collection merchandising and product sorting.
• Optimize onsite search and filtering.
• Review and improve navigation based on heatmap and click data.
• Set up or migrate email marketing flows (welcome, abandoned cart, post-purchase).

Days 61–90: Optimize

• Run conversion rate tests on product pages and checkout.
• Launch lifecycle email campaigns.
• Explore new sales channels available through the Shopify App Store.
• Evaluate apps for reviews, loyalty, or personalization that weren't available on BigCommerce.

Migrating from BigCommerce to Shopify doesn't have to be a white-knuckle experience. The merchants who do it well follow a clear sequence: Plan thoroughly, export cleanly, import methodically, and protect SEO.
