Expert tips & checklist for BigCommerce to Shopify migration

If you’re reading this, you’re probably already a little frustrated.

Maybe BigCommerce started strong, but now it feels clunky. Too rigid. Too expensive to customize. Or maybe your marketing team keeps asking for integrations that take weeks to implement, if they’re even possible. And don’t get me started on how hard it is to scale without tripping over hidden fees.

If that hits close to home, you’re not alone. We’ve worked with clients who tried to squeeze every last drop out of BigCommerce before finally deciding: it’s time to move on. And 9 times out of 10, they land on Shopify. Not because it’s the “trendier” option, but because it gives them something most platforms can’t: control.

Control over the customer journey. Over the tech stack. Over the cost structure. Over how fast you can launch, test, pivot, and grow.

Migrating from BigCommerce to Shopify is a strategic decision. One that can cut long-term costs, open the door to more sales, and drastically improve your team’s efficiency. For C-level execs and founders, it means fewer limitations and more room to build the experience your customers expect, not the one your CMS allows.

This guide is for you if you’re leading the migration internally or partnering with an external dev team. I’ll walk through key reasons to make the switch, what data you can (and should) move, how to dodge common pitfalls, and the tactical roadmap I’ve seen work across real e-commerce projects.

Key takeaways

Shopify offers more flexibility and control than BigCommerce, especially for teams looking to grow without hitting platform limitations.
Most core data can be migrated (products, customers, orders, discounts, content) but clean mapping and testing are critical.
SEO, UX, and app integrations require planning — rushing these steps is the fastest way to lose traffic and customer trust.
A successful migration follows four stages: assessment, planning, execution, and post-launch optimization. Each with its own risks.
The biggest cost isn’t the move itself, it’s fixing avoidable mistakes: broken redirects, bad imports, untested flows, and staff confusion.

Why migrate from BigCommerce to Shopify

In short, Shopify gives you more flexibility, better scalability, and fewer technical limitations than BigCommerce, especially as your business grows.

If you’re thinking about migrating from BigCommerce to Shopify, it’s probably not just a whim. It’s a signal that your current platform is starting to get in the way of how you want to run your business. We’ve seen this play out more times than we can count. The tools feel outdated. Customizations take forever. Scaling costs creep up without warning. And suddenly, your team is spending more time patching workarounds than actually growing the store.

Scalability and flexibility

Shopify is built for growth. Whether you’re adding new product lines, expanding into new markets, or handling flash-sale traffic spikes, it keeps up without breaking a sweat. No performance bottlenecks. No dev-side panic. You get flexible APIs, built-in multi-channel selling, and a backend your team won’t dread opening on Monday morning.

And when business needs shift? Shopify’s app ecosystem and integrations let you pivot fast, without hiring a full dev squad for every minor change.

Customization and user experience

If your current storefront looks like a template from 2015 — or worse, it acts like one — Shopify gives you a clean slate. Their themes are more functional, more flexible, and way easier to customize without breaking user experience in the process.

Want to guide users through a curated funnel? Done. Need to test new layouts for conversion? You’re in control. The result? A storefront that feels like your brand and performs like your best sales rep.

Improved mobile optimization

Here’s the uncomfortable truth: if your mobile experience is even slightly off, you’re bleeding revenue. And with BigCommerce, mobile optimization often means wrestling with outdated themes or layering plugins just to get responsive behavior.

Shopify, on the other hand, is mobile-first by design. Their themes adapt seamlessly across devices, checkout flows are optimized for thumbs, and speed is fast enough to keep customers from bouncing. It’s the kind of experience that doesn’t just look good, it sells better.

Advanced analytics and reporting

You can’t grow what you don’t track. Shopify gives you access to data that’s actually usable, not buried in confusing menus or scattered across plugins. Their analytics dashboards are clean, customizable, and deep enough to make real decisions from.

Want to see how a promo code impacted repeat purchases? Or which funnel step is leaking the most revenue? Shopify’s reports (plus integrations with tools like Google Analytics, Klaviyo, and more) make those insights accessible without hiring a data analyst.

Better app ecosystem and integrations

Shopify’s app store is more mature. You’ll find vetted tools for everything from AI-driven personalization to complex ERP connectors. And these aren’t janky workarounds. They’re apps built with Shopify’s architecture in mind, which means faster setup, fewer conflicts, and actual support.

If you’ve ever lost hours debugging a half-baked integration on BigCommerce, you know how valuable that is.

We’ve migrated stores where teams were spending 10+ hours a week just keeping things from breaking: fixing product feeds, chasing down sync issues, rebuilding abandoned cart flows that never worked right. Shopify doesn’t eliminate complexity, but it gives you the tools to manage it without babysitting every single integration. That’s what makes the difference long-term.

Lower long-term maintenance costs

BigCommerce’s pricing can be deceptive. Between plan limitations, extra fees, and paid add-ons, what starts off cheap often becomes an expensive compromise. Shopify’s pricing tiers are transparent. And once you’re on Shopify Plus, you’ll notice the operational cost curve flattens instead of ballooning.

Fewer dev hours. Fewer plugin disasters. Lower payment processing fees if you use Shopify Payments. That’s real savings, not just in money, but in time.

Need clarity before making the switch?

Data that can be migrated from BigCommerce to Shopify

You can migrate products, customer profiles, orders, discounts, content pages, and more from BigCommerce to Shopify. But not everything will transfer cleanly. Here’s the catch: just because something can be moved doesn’t mean it’ll map over neatly. That’s where businesses often hit a wall. To keep your operations intact post-migration, you’ll want to know what’s transferable, what needs adjustment, and what absolutely can’t be skipped.

Let’s walk through the main data categories and what to watch for.

Products

Products are the backbone of your store, and yes, they can be migrated, but not all fields are created equal. Here’s what typically comes over:

title
post URL
body/description
author (optional, mostly for internal tracking)

summary thumbnail image
publication date
tags (optional)
meta description

Watch out for: Complex product options, custom fields, and variant logic. Shopify handles product variants differently than BigCommerce, so if you’re using nested options or custom modifiers, you may need to restructure how your products are set up.

Also, if you’re using trashed products in BigCommerce (like archived SKUs), they’ll likely show up as archived in Shopify, not active.

Orders

Order history is critical for both customer service and tax reporting. And yes, you can migrate it. The order data you can bring over includes:

order ID
date ordered
status
contact info
tax, discount, subtotal, grand total

customer name (first and last)
company (if applicable)
shipping and billing addresses
phone
order items: product name, price, quantity, SKU

Watch out for: Order statuses don’t always translate 1:1. You may need to map your “Awaiting Fulfillment” or “Shipped” tags into Shopify’s status logic. Also, historical payment data might not carry over depending on how payments were processed, so check with your provider.

Collections

Collections (a.k.a. categories) are fully supported, but handled differently. Shopify focuses more on automated collections (rule-based) and manual ones.

Watch out for: If you have deep nesting or parent/child category logic in BigCommerce, you’ll need to rethink your structure using tags or rules in Shopify.

Redirects

This is a big one for SEO. Every single URL that’s changing should have a proper 301 redirect set up.

Watch out for: Don’t wait until after launch. Map your legacy URLs and set up redirects before the site goes live, especially for high-traffic product and category pages.

Customer profiles

Customer records are highly portable, and Shopify lets you bring over:

first name, last name
email
phone
store credit balances (optional, via metafields or apps)

customer address info
company (if used)
full address data (lines 1 and 2, city, ZIP/postcode, country, state/province)
phone number

Watch out for: Passwords can’t be migrated. Due to encryption differences, customers will need to reset their passwords the first time they log into your new store. This is unavoidable but manageable if you communicate it early (we’ll cover this in the risk section).

Discounts

Your discount logic may need adjusting, but the core fields migrate cleanly:

coupon name and code
discount type (percentage, fixed, etc.)
expiration

uses per customer
discount amount
qualifying conditions (applies to minimum purchase)

Watch out for: Shopify’s discount engine is flexible but works differently from BigCommerce. Some conditional logic (like user segmentation) might need to be recreated manually or via apps.

CMS pages

If you’ve got About pages, shipping policies, and FAQ sections, those come too, including:

page name
page URL
page content (HTML supported)

page title
meta description

Watch out for: Formatting might break, especially if your original content used hardcoded CSS or embedded scripts. Always review imported pages visually before launch.

Blogs

Blog content transfers over, including:

title
post URL
body
author

summary thumbnail image
publication date
tags (optional)
meta description

Watch out for: Shopify blogs are more limited than full-scale CMS platforms. If you rely heavily on dynamic blog layouts or content blocks, be prepared to adapt your formatting.

We know where migrations break — and how to keep yours on track.

Key considerations for a smooth migration from BigCommerce to Shopify

To migrate smoothly, you need to plan for data integrity, SEO preservation, UX consistency, app compatibility, and team readiness, not just the tech transfer.

Moving from BigCommerce to Shopify is basically rebuilding your store in a new ecosystem without breaking everything that was working. The tech side is only half the challenge. The real risk is operational disruption: lost orders, broken layouts, SEO drops, and confused customers. Here’s what to focus on if you want this migration to be smooth.

Data migration: products, customers, and orders

First things first — your data. If it’s inconsistent or incomplete, things unravel fast. Every product detail, customer profile, and order history needs to land in Shopify with accuracy and structure.

What to do:

Audit your current data before the move. Clean up duplicates, fix broken variants, and archive outdated listings.
Align fields early. Shopify and BigCommerce use different data schemas, especially for variants and collections.
Use a tool like Matrixify, or better yet, partner with a migration team that’s done this before. DIY might seem cheaper, but one broken import script can set you back days.

Website design and user experience

Your old theme isn’t coming with you. And that’s a good thing because it’s your chance to rethink the experience. But don’t just clone the layout. Shopify’s frontend is more flexible, so use that to your advantage.

What to do:

Choose a responsive theme that’s optimized for conversion, not just aesthetics.
Rebuild core UX flows (product pages, search, filters, checkout) with mobile-first behavior in mind.
Test, test, test. Especially on mobile. What looks good on desktop may fall apart on a phone.

SEO considerations

This is where even good migrations go wrong. One missed redirect or broken page can tank your rankings overnight. SEO should be planned at the same time as design and data, not slapped on afterward.

What to do:

Map every old URL to its new Shopify equivalent.
Set up 301 redirects before launch, not during.
Review and migrate meta titles, descriptions, canonical tags, and structured data.
Keep an eye on index coverage and crawl errors in Google Search Console post-migration.

Third-party app integrations

Here’s the part most folks underestimate. You’ll probably replace some of your old BigCommerce extensions with new Shopify apps, but not all replacements are plug-and-play.

What to do:

List out every integration you currently rely on: ERP, accounting, reviews, email, live chat, loyalty, subscriptions, etc.
Check compatibility and feature parity in the Shopify App Store.
Plan for testing time. Even apps with the same function often behave differently across platforms.

Testing and quality assurance

No matter how careful your setup is, things will break. Testing is where you catch the worst of it before customers do.

What to do:

Run full end-to-end user flows: homepage → product → cart → checkout → confirmation.
Test different device types, screen sizes, browsers, and payment gateways.
Double-check customer account access, including order history and password resets.
Don’t forget: 404 pages, search functionality, and mobile responsiveness need just as much attention.

Training and support

This one gets overlooked. You may be switching platforms, but your staff still has to run the store. Shopify’s admin is intuitive but different.

What to do:

Train your team on product updates, fulfillment, refunds, and reporting.
Create quick standard operating procedures (SOPs) or Loom videos for new workflows.
Set up internal support channels so people can ask questions before launch day hits.

Launch without SEO drops, broken flows, or surprise bugs.

Mitigating the risks of migrating from BigCommerce to Shopify

Every migration comes with risk: data loss, SEO drops, downtime, broken integrations. That’s not fear-mongering, it’s reality. And sweeping those risks under the rug is exactly how projects end up delayed, over budget, or worse, live with broken customer journeys. But here’s the upside: most of the damage is avoidable if you plan for it upfront.

Let’s break down the risks that catch teams off guard and what to do about them.

Data loss or corruption

It’s not just about missing SKUs. If order histories don’t migrate, customer records get scrambled, or product attributes go missing. And your team ends up scrambling for weeks. Worse, customers may lose trust if their accounts or past purchases disappear.

The non-negotiable reality: Passwords won’t transfer. That’s a platform limitation, not a bug. Shopify encrypts passwords differently, so your users will need to reset theirs.

What to do:

Back up everything: product feeds, customer lists, orders, CMS pages.
Do a pre-migration audit to identify gaps and prioritize high-impact records.
Communicate password resets ahead of time. Use email and in-store banners to prepare users.
Need expert backup? Our data protection services can handle sensitive migrations without cutting corners.

SEO ranking drops

You’ve worked hard to earn your search rankings. But during a migration, it’s easy to break everything Google likes about your site, especially if your URLs, metadata, or structured data are changing.

What to do:

Implement 301 redirects for every old URL (not just the top 20 pages).
Migrate meta titles, descriptions, and canonical tags precisely.
Set up Google Search Console for the new domain structure before launch.
Run a pre-launch SEO audit, preferably with someone who knows ecommerce platforms inside out.

Disruption of customer experience

Let’s say your store launches with broken filters, missing images, or a half-working checkout. That’s not just embarrassing, it’s expensive. Customers don’t wait around. They bounce.

What to do:

Run functional tests on every core user journey: homepage > product > add to cart > checkout > confirmation.
Test all payment methods, shipping options, and discounts.
Do soft launches (aka staged rollouts) where possible to reduce traffic disruptions.
Monitor post-launch performance closely for the first 7–14 days.

Integration issues with third-party apps

One broken integration can shut down order fulfillment or freeze customer support. If you’re using ERPs, CRMs, accounting software, or shipping platforms, they need to work on day one.

What to do:

Inventory every app or third-party tool you’re currently using.
Check Shopify compatibility. Look for native integrations or APIs if direct apps don’t exist.
Test integrations in a staging environment before cutover.

Unexpected costs and overruns

Migrations always cost more when you underestimate complexity. That plugin that “should’ve worked”? Suddenly, it needs custom dev work. That layout tweak? Now it’s a frontend rebuild.

What to do:

Work with a migration partner who can give you a detailed project scope, not just a ballpark figure.
Add a 15–20% buffer for surprise tasks or delays.
Get a realistic timeline based on actual data volume, custom features, and third-party systems.

Loss of custom features

If you’ve built custom workflows or third-party integrations into BigCommerce, you’ll probably need to rebuild some of them on Shopify. The two platforms don’t speak the same language under the hood.

What to do:

Audit all custom features: payment rules, subscription logic, multi-step forms, etc.
Identify which can be replicated with Shopify apps, which need custom development, and which should be retired.
Want help rebuilding unique ecommerce flows? Our app development team specializes in custom Shopify solutions that don’t fall apart post-launch.

Downtime during migration

No one wants to shut the store down. But depending on your architecture and go-live strategy, some downtime might be unavoidable.

What to do:

Schedule migration during off-peak hours (e.g., overnight or low-traffic weekends).
Use a phased migration strategy if you need to keep parts of the store live.
Communicate clearly with your audience, even a short banner with expected downtime can preserve trust.

Protect your traffic, data, and revenue during migration.

Strategic roadmap for a seamless transition

Migrating from BigCommerce to Shopify is a business-critical project with moving parts across data, UX, operations, and SEO. On paper, it only includes four stages — assessment, planning, execution, and post-migration — but don’t be deceived. Each one hides complexity that can derail your timeline if you’re not prepared.

Here’s the roadmap we follow, refined from years of doing this for ecommerce brands with thousands of SKUs, international fulfillment, and custom logic that can’t afford to go offline.

Phase 1 – assessment: map what you have before you move

Think of this as your pre-flight checklist. Before anything moves, you need to know what you’re working with — and what you’re walking away from.

What to do:

Inventory your store assets: Products, variants, categories, images, customer groups, discounts, custom shipping rules, blog content — all of it. Use this to plan the data migration schema.
List your integrations and automations: ERP, CRM, shipping, returns, marketing tools, subscriptions, loyalty programs. For each, note what it does, if there’s a Shopify-compatible version, what needs to be rebuilt from scratch.
Identify legacy issues: Are there bloated categories? Broken product relationships? Overcomplicated discounts? Now’s your chance to clean house instead of migrating a mess.
Review performance data: Use GA4, Search Console, and heatmaps to understand what’s working and what’s not. This helps you prioritize what needs to survive the migration.

Phase 2 – planning: don’t skip the boring stuff

This is the least glamorous phase, and the one that saves the most time later. You’re building your playbook: who’s doing what, when, and with what tools.

What to do:

Choose your Shopify plan wisely: Shopify gives you access to customizable checkout flows, API rate boosts, and support, which is crucial for high-volume or international stores.
Define your go-live date, then reverse-engineer milestones: Plan sprints for theme setup, data import and mapping, app installation and testing, SEO config and redirects, QA, staff training.
Create your field mapping schema: Match BigCommerce export fields to Shopify import templates. Flag anything that needs transformation (like options > variants logic).
Design user flows, not just screens: Focus on how people shop. This includes navigation logic, filtering behavior, mobile cart flow, and checkout speed.
Prep customer communication plans: If passwords will be reset, accounts will be unavailable, or site downtime is expected, don’t leave users guessing. A single email can prevent 100 support tickets.

You are all set to migrate BigCommerce to Shopify correctly.

Phase 3 – execution: build smart, test often

Now you’re in build mode. It’s iterative. That means testing early and fixing fast.

What to do:

Set up your staging Shopify store: Use this to sandbox theme dev, app installs, and data test runs.
Clean and import data in stages: Start with products. Then test customers, orders, and collections. Validate the structure, tags, variants, and SEO fields. Run spot checks.
Configure Shopify checkout and settings: Shipping zones, taxes, payment gateways, transactional emails, and GDPR settings — they all need manual setup.
Install apps one at a time, test each in isolation: Don’t dump 10 tools into the store and hope for the best. Conflicts are real.
Configure redirects, custom URL rules, and canonical tags: You want a 1:1 match where possible. Use Shopify’s URL redirect tool or an advanced app like Easy Redirects for large volumes.

Phase 4 – post-migration optimization: launch is not the finish line

Once you go live, things will break. Users will find edge cases your team didn’t. That’s expected. What matters is how fast you fix, optimize, and learn.

What to do:

Monitor key metrics daily for the first 2 weeks: Bounce rate, Add-to-cart rate, Checkout drop-offs, Revenue per session, 404 errors.
Use session replay tools like Hotjar or Lucky Orange: See what users are doing and where they’re getting stuck.
Tweak navigation, filter logic, or layout based on actual usage: Don’t just copy BigCommerce layouts out of habit, adapt based on user behavior.
Update and retrain internal SOPs: Your staff will need to learn new order management flows, inventory processes, or app workflows. Capture those in updated documentation.
Run SEO follow-ups after 30 days: Check for traffic drops, indexation issues, and redirect errors.

Pro tip: Every migration reveals things you didn’t know were broken in the old system. Use this as a reset.

Conclusion

Most migrations fail for one of two reasons: they’re rushed, or they’re treated like a simple content transfer. To transfer BigCommerce to Shopify is neither quick nor trivial. It’s a full-scale rebuild, and if done right, it becomes a turning point for your ecommerce operations.

You get a faster, cleaner, more flexible storefront. A backend your team can actually work with. Tools that don’t require weeks of dev time just to sync inventory or launch a discount. And in the long run, fewer hidden costs and more room to grow.

But the benefits only show up when the foundation is solid. That means detailed planning. Clean data. Real testing. A launch strategy that accounts for SEO, UX, and third-party tools.

If you want this done without the guesswork, with a team that’s handled the messy edge cases before, we’re here.
