Migrate Miva Merchant to BigCommerce: The Ultimate 2025 Guide
Seamlessly Migrate Your Store from Miva Merchant to BigCommerce
Are you considering a pivotal move for your e-commerce business? Migrating your online store from Miva Merchant to BigCommerce can unlock a world of enhanced features, improved scalability, and a more robust platform to drive your growth. While the thought of a platform switch, or replatforming, might seem daunting, this comprehensive guide will walk you through every essential step, ensuring a smooth and efficient data transfer.
BigCommerce offers a modern, API-driven architecture, making it an attractive target for merchants looking to upgrade their user experience, streamline operations, and boost their online presence. This article provides a clear, actionable roadmap for transitioning your valuable store data, including products, customers, and orders, to your new BigCommerce storefront.

Prerequisites for a Successful Migration
Before initiating the data migration process, thorough preparation of both your existing Miva Merchant store and your new BigCommerce environment is crucial to ensure data integrity and minimize downtime.
- Miva Merchant (Source Store) Preparation:
- Data Export: Since Miva Merchant is not directly supported by our automated migration tool, you will need to export your store's data into CSV files. This includes critical information such as products (SKUs, variants, descriptions, images), product categories, customer data, order history, manufacturers, reviews, and CMS pages. Ensure your CSV files are well-structured and accurate. Learn more about CSV.File Data Migration.
- Data Review: Carefully review your Miva Merchant data for any inconsistencies, outdated information, or duplicate entries. Clean data leads to a cleaner migration.
- For a detailed guide on preparing your source store, consult our FAQ on preparing your source store for migration.
- BigCommerce (Target Store) Preparation:
- New Store Setup: Have a fresh BigCommerce store ready. While you can opt to “Clear Target” existing data during migration, starting with a clean slate is often recommended.
- API Access Credentials: BigCommerce relies on API access for data transfer. You will need to generate specific credentials: a Client ID, an Access Token, and your store's API Path. These are typically obtained by creating a custom API account or app within your BigCommerce admin panel, ensuring it has the necessary read/write scopes for the data you intend to migrate. Remember that HTTPS is required for BigCommerce API access.
- Plugin Requirements: BigCommerce migrations require a custom app with specific scopes to facilitate the data transfer.
- For guidance on setting up your target store, refer to our FAQ on preparing your target store for migration and The Short & Essential Guide to Access Credentials.
Performing the Migration: A Step-by-Step Guide
Step 1: Connect Your Source Store (Miva Merchant via CSV)
Begin by selecting “CSV.File to Cart” as your source platform in the migration wizard. You will then be prompted to upload your prepared CSV files containing your Miva Merchant data. Our system will analyze these files, readying your products, categories, customers, and other entities for the move.

Step 2: Connect Your Target Store (BigCommerce)
Next, choose “BigCommerce” as your target shopping cart from the dropdown menu. Enter your BigCommerce store's URL. You will then input the crucial API credentials you generated: the Client ID, Access Token, and API Path. These details securely establish the connection, allowing for the data transfer to commence.

Step 3: Select Data Entities for Migration
This is where you define the scope of your migration. You can choose to transfer all entities or select specific data types to move. Our tool supports the migration of a wide range of entities from your CSV files to BigCommerce, including:
- Products (including SKUs, variants, attributes)
- Product Categories & Manufacturers
- Customers
- Orders
- Coupons
- Blogs & Blog Posts
- CMS Pages
Select the checkboxes for the entities you wish to move to your new BigCommerce store.

Step 4: Configure Additional Migration Options
To tailor your data transfer, you’ll encounter a series of additional options. These settings allow for precise control over how your data is treated during the move:
- Preserve IDs: Options like “Preserve Orders IDs,” “Preserve Product IDs,” “Preserve Category IDs,” and “Preserve Customers IDs” help maintain your data structure. Learn more about how Preserve IDs options can be used.
- SEO URLs & 301 Redirects: Selecting “Create 301 SEO URLs” is highly recommended. This crucial feature automatically generates 301 redirects from your old Miva Merchant URLs to the new BigCommerce URLs, preserving your valuable SEO rankings and link equity.
- Migrate Images: Choose to “Migrate Images in Description” to ensure product images and other media embedded in your descriptions are transferred.
- Password Migration: This option allows for the secure transfer of customer passwords.
- Clear Target: Decide whether to clear all current data on your BigCommerce store before the migration begins.
- Create Variants from Attributes: If your Miva Merchant products use attributes that need to be converted into BigCommerce product variants, select this option.

Step 5: Map Customer Groups & Order Statuses
Data mapping is a critical step for ensuring consistency in your new store. Here, you will match your existing Miva Merchant (via CSV) customer groups and order statuses to their corresponding equivalents in BigCommerce. This ensures that your customer segments and order workflows remain accurate and functional post-migration.

Step 6: Run a Free Demo Migration
Before committing to the full replatform, we highly recommend running a free demo migration. This transfers a limited number of entities (e.g., 10 products, 10 customers, 10 orders) to your BigCommerce store. It allows you to:
- Preview how your data will appear in the new environment.
- Verify data integrity and accuracy.
- Familiarize yourself with the process and make any necessary adjustments before the full transfer.
Step 7: Initiate Full Data Transfer
Once you are satisfied with the demo results and all configurations, proceed with the full data migration. You can also select a Migration Insurance Plan for added peace of mind, offering remigrations for a specified period. The process will run in the background, allowing you to monitor its progress without interrupting your daily operations.

Post-Migration Steps: Securing Your New Store’s Success
The journey doesn’t end when the data transfer is complete. Several crucial post-migration tasks are essential to ensure your new BigCommerce store is fully operational, optimized, and ready for customers.
- Thorough Data Verification: Rigorously check all migrated data. Verify product details, images, prices, SKUs, inventory levels, customer accounts, order histories, and reviews. Ensure that metadata for SEO is also correctly transferred.
- Configure Store Settings: Set up essential BigCommerce store configurations, including shipping zones, tax rules (multi-tax allowed), payment gateways, and store currencies.
- Install Apps & Integrations: Explore the BigCommerce App Store to find apps that replicate or enhance the functionality you had on Miva Merchant. This might include marketing tools, accounting integrations, or customer service solutions.
- Design & Theming: Customize your BigCommerce theme to align with your brand identity. Ensure a seamless user experience (UX) and mobile responsiveness.
- Implement 301 Redirects: Even if you opted for automatic 301 redirects during migration, it's vital to manually check and implement any additional redirects for pages that might have changed URLs, preserving crucial SEO rankings and preventing broken links.
- Update DNS Records & Go Live: Once everything is verified, update your DNS settings to point your domain to your new BigCommerce store. Plan this step carefully to minimize downtime for your customers.
- User Acceptance Testing (UAT): Conduct comprehensive testing of all critical functionalities, including product browsing, adding to cart, checkout, account creation, and order placement.
- Inform Your Customers: Announce your new and improved store to your customer base. Highlight new features or improvements they can expect.
