Every year, thousands of brands outgrow their eCommerce platforms; some even call it the “digital molting” stage of business. BigCommerce sellers in particular often feel the squeeze of revenue-based fees and scaling limits.
Learning how to migrate from BigCommerce to Shopify is less about moving data and more about unlocking a storefront built to grow without hidden penalties.
BigCommerce Migration Blueprint: Your 14-Step Business-First Approach
Successfully migrating from BigCommerce to Shopify requires careful planning and systematic execution to protect your revenue stream and customer relationships. This business-first methodology ensures data integrity while maintaining operational continuity throughout the entire process.
Let's walk through the complete 14-step process that covers everything from initial planning to post-launch optimization:
Step 1: Complete Store Assessment and Business Impact Planning

Your migration's success starts with understanding every aspect of your current business operations. This comprehensive assessment prevents costly oversights and ensures nothing critical gets lost during the transition.
- Document all BigCommerce store features currently in use
- Identify critical business periods to avoid during migration
- Calculate current BigCommerce costs vs projected Shopify costs
- Create a detailed inventory of all integrations and third-party tools
- Establish success metrics and KPIs to track migration performance
Pro Tip: Create a comprehensive spreadsheet documenting every payment gateway, shipping rule, promotional setup, and custom feature. This document becomes your migration roadmap and prevents feature gaps that could disrupt customer experience. Include screenshots of complex configurations that might be difficult to recreate from memory.
Step 2: Choose Your Shopify Plan and Initial Setup
Selecting the right Shopify plan impacts your migration strategy and long-term operational costs. Your plan choice should align with transaction volume, team size, and advanced feature requirements.
- Select an appropriate Shopify plan based on BigCommerce's transaction volume
- Set up a Shopify account with business information
- Configure basic store settings (currency, timezone, tax settings)
- Purchase and install the chosen Shopify theme
- Set up password protection for the development phase
Consider Shopify Basic for stores under $50K monthly revenue, Standard for growing businesses needing advanced reports, or Advanced for high-volume operations requiring detailed analytics. Factor in transaction fees, staff account requirements, and international selling capabilities when making your decision.
Step 3: Export All Data from BigCommerce
Data extraction requires precision to ensure complete information transfer without corruption or loss. BigCommerce's export tools are comprehensive but need systematic use for optimal results.
Export Your Product Catalog Systematically
Navigate to BigCommerce Admin → Settings → Data Export to access native export functionality. Export your product catalog first, ensuring inclusion of all variants, custom fields, bulk pricing rules, and product relationships.
- Product names, SKUs, and descriptions with full details
- Pricing information, including special prices and bulk discounts
- Product attributes, categories, and variant configurations
- Stock levels, weight data, and inventory tracking information
Extract Customer Information Securely
Customer data represents your business's most valuable asset, requiring careful handling throughout the export process. Focus on essential information while maintaining privacy compliance standards.
- Main customer files with names, emails, and registration dates
- Billing and shipping address information is stored separately
- Customer group assignments and newsletter subscription status
- Purchase history and customer lifetime value calculations
Remember that customer passwords cannot be exported for security reasons, requiring customers to reset passwords on your new Shopify store.
Handle Order Data with Special Care
Order export presents unique challenges due to complex relationships between customers, products, and payment information. Prioritize recent order data for business continuity.
- Recent orders from the last 6-12 months for most businesses
- Complete order details, including product variants and quantities
- Payment status, shipping information, and customer notes
- Order status tracking and fulfillment history
Consider using specialized tools like Cart2Cart or LitExtension for complex order data that includes custom fields or specialized configurations.
Secure All Digital Assets
Download all product images and media files from your BigCommerce File Manager. These visual assets require special organization for efficient import.
- Product images, including main photos and additional gallery images
- Category banners and promotional graphics
- PDF files, user manuals, and downloadable content
- Custom graphics and brand assets are used throughout the store
Organize files logically with clear naming conventions that include product SKUs or categories for easier identification during the import process.
Step 4: Prepare and Clean Your Data for Shopify

Clean, organized data imports faster and performs better in your new environment. This preparation step prevents ongoing operational headaches and ensures optimal store performance.
- Review exported CSV files for data quality issues
- Remove duplicate or outdated customer records
- Standardize product SKUs and naming conventions
- Organize product images and rename them for easy identification
- Create a product collections/categories mapping document
Use this opportunity for strategic data cleanup by removing discontinued products, inactive customer accounts, and outdated category structures that no longer serve your business model. Clean data migrates faster and performs better on your new Shopify store.
Step 5: Import Products to Shopify
Product import success requires patience and systematic verification to ensure accurate pricing, variants, and product relationships transfer correctly.
Format Your CSV Files Perfectly

Download Shopify's official CSV templates from their help documentation. Proper formatting prevents costly import failures that can set back your migration timeline significantly.
- Match column headers exactly to Shopify's requirements
- Clean up special characters that might break imports
- Verify data types, ensuring numbers are formatted as numbers
- Test with small batches before importing your entire catalog
Map BigCommerce Data to Shopify Structure
Understanding how BigCommerce data translates to Shopify's structure prevents import failures and ensures smooth data transition.
- Product titles and descriptions transfer with minimal modification
- BigCommerce categories become Shopify collections
- Custom attributes may need restructuring as product tags or metafields
- Pricing must match Shopify's decimal formatting requirements
Handle Shopify's Variant Limitations Strategically
Critical limitation alert: Shopify allows a maximum of 100 variants and 3 options per product, which may require restructuring complex BigCommerce products.
- Audit complex products before migration to identify issues
- Split products exceeding variant limits into multiple listings
- Restructure option combinations to fit within Shopify's constraints
- Plan alternative solutions for highly customizable products
Use Shopify's native CSV import tool found in Products → All Products → Import. Upload product data in manageable batches of 50-100 products to monitor for errors and verify successful imports.
Step 6: Import Customer Data to Shopify

Customer data migration requires careful handling to maintain privacy compliance while ensuring smooth account transitions for your valued customers.
- Use Shopify's customer import feature in the Customers section
- Upload the customer CSV file with required fields (email, name, addresses)
- Send account activation emails to customers for password setup
- Verify customer groups/tags are properly assigned
- Test customer login functionality
Prepare a clear communication explaining the migration process and account access changes. Send account activation emails to customers after import, providing simple instructions for password setup. This proactive approach prevents customer service overwhelm during the transition period.
Step 7: Configure Shopify Store Settings
Proper store configuration ensures smooth business operations from day one. These fundamental settings affect payment processing, tax calculations, and customer communications.
Set Up Payment Processing Systems
Configure payment gateways to match your current BigCommerce setup while taking advantage of Shopify's competitive rates.
- Enable Shopify Payments as the primary gateway for the lowest transaction fees
- Add PayPal Express and customer-preferred payment methods
- Configure regional payment options for international customers
- Test each gateway with small transactions to verify processing
Configure Shipping and Tax Systems
Recreate your shipping configurations exactly to prevent customer confusion about delivery costs and tax calculations.
- Set up shipping zones and rates matching BigCommerce setup
- Configure free shipping thresholds and promotional rates
- Establish tax calculations for all applicable regions
- Test shipping calculations for various location combinations
Customize Communication Templates
Configure email notification templates for order confirmations, shipping notifications, and customer communications. Customize templates to match your brand voice and include essential business information that customers expect.
Step 8: Recreate Store Design and Navigation
Visual consistency maintains customer trust during platform transition. Focus on brand recognition while leveraging Shopify's modern design capabilities.
Maintain Brand Identity Through Design
Your store's design affects everything from user experience to conversion rates. Maintain visual consistency to prevent customer confusion during the transition.
- Customize the Shopify theme to match the brand colors and typography
- Upload logo and configure visual elements for brand recognition
- Recreate key design elements that define your brand identity
- Ensure mobile responsiveness across all devices and screen sizes
Structure Navigation for User Experience
Create intuitive navigation systems that help customers find products easily while taking advantage of Shopify's navigation capabilities.
- Recreate the main navigation menu structure from BigCommerce
- Set up footer links, including legal pages and customer service
- Add homepage content featuring the best products and promotions
- Optimize category structures for improved product discovery
Mobile optimization is critical since over 60% of e-commerce traffic comes from mobile devices. Test thoroughly on various devices to ensure optimal user experience.
Step 9: Set Up SEO and URL Redirects
Preserving search engine rankings protects years of SEO investment and prevents devastating traffic losses that can take months to recover.
Understanding URL Structure Differences

BigCommerce and Shopify use different URL structures that require comprehensive mapping for proper redirect implementation.
- BigCommerce Products: yourstore.com/product-name/
- Shopify Products: yourstore.com/products/product-name
- BigCommerce Categories: yourstore.com/category-name/
- Shopify Collections: yourstore.com/collections/category-name
Create Comprehensive URL Mapping
Build a detailed spreadsheet mapping every important URL from your BigCommerce store to its new Shopify equivalent.
- Export all URLs from your BigCommerce sitemap
- Map each old URL to its corresponding new Shopify URL
- Prioritize high-traffic pages and revenue-generating products
- Include blog posts, category pages, and informational content
Don't skip any pages - even a few missing redirects can cost significant traffic and revenue.
Implement 301 Redirects in Shopify
Navigate to Online Store → Navigation → URL Redirects in your Shopify admin to configure redirect rules.
- Import redirect lists using Shopify's CSV template for bulk uploads
- Test critical redirects manually to verify proper functionality
- Use pattern-based redirects for systematic URL changes
- Monitor redirect performance using Google Search Console
Preserve SEO Assets and Meta Data
Transfer all meta titles, descriptions, and image alt text from your BigCommerce store to maintain SEO continuity.
- Copy product meta information for search engine optimization
- Transfer category descriptions and collection SEO settings
- Preserve image alt text for accessibility and image search
- Set up Google Analytics 4 and Search Console tracking
This SEO data represents significant optimization value accumulated over years of work.
Step 10: Install and Configure Essential Apps
Strategic app selection replaces BigCommerce functionality while often providing enhanced capabilities not available on your previous platform.
Research Apps for Functionality Replacement
BigCommerce includes many native features that require apps on Shopify. Research thoroughly to find the best replacements.
- Judge.me or Yotpo for customer reviews and ratings
- Klaviyo or Mailchimp for email marketing automation
- ReConvert or Bold Upsell for post-purchase optimization
- Searchanise or Instant Search+ for advanced search functionality
Configure Marketing and Customer Tools
Set up email marketing integration if you're changing platforms from your BigCommerce setup, ensuring continuity in customer communication.
- Export customer email lists from BigCommerce
- Configure automated welcome sequences and cart abandonment emails
- Set up customer segmentation based on purchase history
- Install loyalty program apps if needed for customer retention
Research apps using reviews, feature comparisons, and free trial periods before committing to paid subscriptions that affect your operational budget.
Step 11: Test Everything Before Going Live
Comprehensive testing prevents costly mistakes and ensures flawless functionality when customers visit your new store.
Execute Comprehensive Functionality Testing
Testing every aspect of your store prevents embarrassing launches and lost sales due to technical issues.
- Place multiple test orders using different payment methods and shipping addresses

- Monitor customer service channels for migration-related inquiries
Keep your BigCommerce store active for at least 30 days as a safety backup while monitoring traffic transition and resolving any unforeseen issues.
Step 14: Post-Launch Monitoring and Optimization
The first 30 days after launch are critical for success. Active monitoring prevents small issues from becoming major customer complaints.
Establish Performance Tracking Systems
Monitor key performance indicators daily to measure migration success and identify areas needing immediate attention.
- Track website traffic, conversion rates, and average order value
- Compare metrics against BigCommerce baseline performance
- Monitor page loading speeds and site performance metrics
