GSI Commerce to BigCommerce Migration - Step-by-Step Guide & Expert Services

Seamlessly Transition Your Store from GSI Commerce to BigCommerce

Replatforming your e-commerce store is a strategic move that can significantly enhance your operational efficiency, scalability, and customer experience. If you're currently operating on GSI Commerce and considering a switch to a more modern, feature-rich platform, BigCommerce stands out as an excellent choice. This comprehensive guide will walk you through the entire process of migrating your store data from GSI Commerce to BigCommerce, focusing on clarity, actionable steps, and ensuring data integrity throughout your transition.

Given that GSI Commerce typically doesn't offer direct API connections for third-party migration tools, this guide will detail a robust method leveraging CSV file exports from your GSI Commerce platform. This approach ensures all your vital store data—from products and categories to customer information and orders—is meticulously transferred to your new BigCommerce environment.

Prerequisites for a Successful Migration

Before initiating any data transfer, proper preparation is key to a smooth and error-free migration. Here’s what you need to have in place:

• GSI Commerce Data Export: As GSI Commerce is not directly supported by most automated migration tools, you will need to export all your critical store data into CSV files. This includes:
  • Products (SKUs, variants, descriptions, images, prices, stock levels)
  • Product Categories
  • Product Manufacturers
  • Customer data (names, addresses, order history)
  • Orders (statuses, details)
  • Coupons
  • CMS Pages and Blog Posts
  • Product Reviews

  Ensure your CSV files are well-organized and include all relevant fields. For detailed guidance on preparing your source data, refer to our How to prepare Source store for migration? FAQ.

• BigCommerce Store Setup: You will need an active BigCommerce store. This can be a trial store or a paid subscription. Ensure you have administrator access.
• BigCommerce API Credentials: To allow the migration tool to connect and transfer data to your BigCommerce store, you'll need specific API credentials. These include the Client ID, Access Token, and the API Path. You can generate these by navigating to Settings > API Accounts in your BigCommerce admin panel. Remember that BigCommerce connections are API-only, require HTTPS, and might involve custom app development for comprehensive integration. For more details on acquiring these credentials, consult The Short & Essential Guide to Access Credentials for Cart2Cart.
• Backup Your Data: Always create a complete backup of your existing GSI Commerce store data before starting any migration. This ensures you have a fallback in case of unforeseen issues.
• Review BigCommerce Requirements: Familiarize yourself with BigCommerce's specific data import requirements and limitations, including API rate limits, to avoid delays. For target store preparation, see How to prepare Target store for migration?.

Performing the Migration: A Step-by-Step Guide

With your preparations complete, you're ready to begin the migration process. This guide outlines the steps using an automated migration wizard, which streamlines the data transfer.

Before you begin, head to the migration tool's website and select the option to start your migration.

Step 1: Connect Your Source Store (GSI Commerce via CSV)

The first step involves configuring your GSI Commerce data as the source. Since direct integration is not available, you'll utilize the CSV file migration method.

• From the list of supported platforms, select "CSV File to Cart" as your Source Cart.
• Upload the CSV files containing your exported GSI Commerce data (products, customers, orders, etc.). The wizard will guide you through mapping the fields from your CSV to generic data types.

Step 2: Connect Your Target Store (BigCommerce)

Next, you will set up the connection to your new BigCommerce store, which will serve as the destination for your data.

• Choose "BigCommerce" from the Target Cart dropdown menu.
• Enter your BigCommerce store's URL.
• Provide the necessary API credentials: Client ID (Username), Access Token (API Token), and the API Path that you generated earlier from your BigCommerce admin panel.

Step 3: Select Data Entities for Migration

This crucial step allows you to define exactly which data entities you want to transfer from your GSI Commerce CSV files to BigCommerce. You can choose to migrate everything or select specific items.

• Review the list of available data entities, which typically includes Products, Product Categories, Product Manufacturers, Customers, Orders, Coupons, Blogs Posts, and CMS Pages.
• Check the boxes next to the entities you wish to migrate. You can select "All entities" or pick them individually.

Step 4: Configure Additional Migration Options

Enhance your migration with a range of additional options designed to preserve SEO rankings, data integrity, and user experience:

• Preserve IDs: Options like "Preserve Orders IDs," "Preserve Product IDs," "Preserve Category IDs," and "Preserve Customers IDs" maintain the original IDs, which is beneficial for external integrations and record-keeping. Learn more about How Preserve IDs options can be used?.
• Create 301 SEO URLs: This is vital for maintaining your SEO equity. It automatically creates redirects from your old GSI Commerce URLs to the new BigCommerce URLs, preventing broken links and preserving your search engine rankings.
• Migrate Customer Passwords: If supported, this allows customers to log into their new BigCommerce accounts with their existing GSI Commerce passwords.
• Clear Target Store Data: The "Clear Target" option allows you to remove any existing demo data or products from your BigCommerce store before the migration starts, ensuring a clean slate. Read about Clear current data on Target store before migration option.
• Create Variants from Attributes: Essential for products with multiple options (e.g., size, color).

Step 5: Map Data Fields

Data mapping ensures that fields from your GSI Commerce CSV files are correctly assigned to their corresponding fields in BigCommerce. This step is critical for maintaining data consistency and integrity.

• Map customer groups (e.g., "Wholesale" to "Customer Group A").
• Map order statuses (e.g., "Pending" to "Awaiting Payment").
• Map product attributes and options as necessary, especially if you have complex product variants.

Step 6: Run Demo Migration and Full Migration

Before committing to a full data transfer, run a free demo migration to preview the results:

• Demo Migration: This transfers a limited number of entities (e.g., 10-20 products, customers, orders). Carefully review the migrated data on your BigCommerce store to ensure everything looks correct. Check product details, pricing, images, customer accounts, and order history.
• Full Migration: Once satisfied with the demo results, proceed with the full migration. This will transfer all selected data from your GSI Commerce CSV files to your BigCommerce store. Consider adding a Migration Insurance Service for additional peace of mind and the option for remigrations if needed. For more on this, see How Migration Insurance works?.

Post-Migration Steps

The migration doesn't end when the data transfer is complete. A few crucial post-migration steps will ensure your new BigCommerce store is fully functional and optimized.

• Thorough Testing: Conduct extensive testing of your BigCommerce store. This includes:
  • Frontend: Navigate through product pages, categories, perform searches, test the checkout process, and verify customer account functionalities.
  • Backend: Check order management, customer data accuracy, product inventory, and ensure all images and descriptions are correctly displayed.
• SEO Verification: Verify that all 301 redirects are working correctly. Update your sitemaps in Google Search Console and monitor your SEO rankings for any dips or improvements. Preserving your link equity is critical.
• Update DNS Settings: Once you are completely confident with your BigCommerce store, update your domain's DNS settings to point to your new BigCommerce site.
• Configure BigCommerce Settings: Set up your shipping options, tax rules, payment gateways, and any other specific BigCommerce configurations.
• Theme Customization and Apps: Customize your BigCommerce theme to match your brand's aesthetic. Install any necessary apps from the BigCommerce App Store to replicate or enhance functionalities from your GSI Commerce store.
• Consider Recent Data Migration: If there's a period between your GSI Commerce CSV export and the BigCommerce launch, new orders or customer registrations might occur. A Recent Data Migration Service can transfer these incremental updates to ensure no data is lost during the transition.
• Deprecate GSI Commerce: Once your BigCommerce store is live and performing as expected, you can safely decommission your old GSI Commerce platform.
