Migrate BigCommerce to Squarespace: Your Expert Guide to a Seamless E-commerce Transition
A Comprehensive Guide to Transitioning from BigCommerce to Squarespace
BigCommerce offers a powerful suite of e-commerce tools, but many merchants find themselves seeking the streamlined design, intuitive management, and aesthetic focus that Squarespace provides. Replatforming your online store can appear to be a challenging undertaking, yet with the correct strategy and expert guidance, this transition can be both smooth and secure, safeguarding your valuable data and SEO standing.
This detailed guide will walk you through every essential step of migrating your e-commerce data from BigCommerce to Squarespace. Our focus is on ensuring data integrity, preserving your search engine rankings, and maintaining a positive user experience throughout the entire process.
Prerequisites for Migration
Before initiating the migration process, it's crucial to prepare both your BigCommerce source store and your Squarespace target store to ensure a seamless data transfer.
Prepare Your BigCommerce Source Store
- Data Backup: Always perform a complete backup of your entire BigCommerce store, encompassing products, customer information, order history, and all associated media files.
- Administrator Access: Confirm you have full administrator access to your BigCommerce store.
- Gather API Credentials: BigCommerce utilizes an "API only" connection method. You will need to generate specific API credentials:
clientId,accessToken, andapiPath. This typically involves developing a custom app within your BigCommerce admin panel (under Advanced Settings > API Accounts). Ensure this custom app has the necessary scopes to access all the data entities you intend to migrate. For more detailed instructions, refer to The Short & Essential Guide to Access Credentials for Cart2Cart. - HTTPS Requirement: Verify that your BigCommerce store is configured to use HTTPS, as this is a fundamental requirement for secure API access.
- Data Review: Take this opportunity to review your existing data for consistency and clean up any outdated or unnecessary information.

Prepare Your Squarespace Target Store
- Squarespace Account Setup: Establish a new Squarespace account or ensure your existing one is active and configured for e-commerce. Your Squarespace site must be on an eligible Commerce plan.
- Install Cart2Cart Squarespace Migration App: A critical plugin requirement for Squarespace is the installation of the Cart2Cart Squarespace Migration App. This app is vital for securely connecting your Squarespace store and facilitating the data transfer process.
- HTTPS Requirement: Confirm that your Squarespace site is also secured with HTTPS.
- Site Structure Planning: Prior to the data transfer, consider your new Squarespace site's structure, product categories, and any specific design elements you plan to implement.

Performing the Migration: A Step-by-Step Guide
With your stores prepared, you can now begin the data migration process using the dedicated migration wizard.
Step 1: Initiate Your Migration
Start your data transfer by navigating to the migration wizard. Here, you will be prompted to identify both your source and target e-commerce platforms. Select "BigCommerce" as your Source Cart and "Squarespace" as your Target Cart from the dropdown menus.

Step 2: Connect Your BigCommerce Source Store
Next, enter the URL of your BigCommerce store. You will then need to provide the previously gathered API credentials: the Client ID, Access Token, and API Path. These credentials, which originate from the custom app you developed within BigCommerce with the necessary scopes, enable the migration tool to securely access and extract your store's data.

Step 3: Connect Your Squarespace Target Store
Provide your Squarespace Admin URL, along with your administrator email and password. It is essential, as mentioned in the prerequisites, that the Cart2Cart Squarespace Migration App is already installed on your Squarespace site. This specialized plugin is crucial for establishing a secure connection and enabling the smooth transfer of your e-commerce data to the new platform.
While there isn't a specific screenshot for Squarespace target store setup, the process typically involves inputting your Squarespace store's URL and administrative access details, similar to connecting other platforms.
Step 4: Select the Data Entities for Transfer
This stage allows you to specify precisely which types of data you wish to transfer from your BigCommerce store to Squarespace. You have the flexibility to migrate a comprehensive set of entities, including:
- Products (including their variants, attributes, and images)
- Product Categories
- Customers
- Orders
- Coupons
- Blogs Posts
- CMS Pages
- Product Reviews (which Squarespace supports)
- Gift Cards (which Squarespace supports)
You can choose to select all entities for a complete data transfer or individually pick specific items based on your migration requirements.

Step 5: Configure Additional Options and Data Mapping
This is a critical phase where you can refine your migration settings and ensure data consistency.
Additional Migration Options:
You can select various options to tailor the migration process:
- Clear Target Store Data: Opting for this will remove any existing data on your Squarespace store before the migration commences. Read more about this at Clear current data on Target store before migration option.
- Preserve IDs: This important feature allows you to retain the original IDs for orders, products, categories, and customers, ensuring continuity and consistency. Learn more about How Preserve IDs options can be used?.
- Create 301 SEO URLs: This is vital for maintaining your SEO rankings and link equity. The tool will automatically generate 301 redirects from your old BigCommerce URLs to their new Squarespace counterparts.
- Migrate Images in Description: Ensure that all product and category images embedded within your descriptions are successfully transferred.
- BigCommerce Migrate Variants: This option specifically handles the proper transfer of complex product variants from BigCommerce.
- Migrate Groups to Tags: Map your customer groups from BigCommerce to tags within Squarespace.

Data Mapping:
Carefully map customer groups, order statuses, and any other custom fields from your BigCommerce store to their corresponding fields in Squarespace. This step is essential for ensuring data consistency and integrity post-migration, providing a coherent experience on your new platform.

Step 6: Run a Demo and Full Migration
It is strongly recommended to first perform a free demo migration. This allows you to review a sample of your migrated data on Squarespace and identify any potential issues or adjustments needed before committing to the complete data transfer.
Once you are fully satisfied with the results of the demo, proceed with the full data migration. During this final stage, you might also consider purchasing a Migration Insurance Service. This service provides peace of mind by allowing for multiple re-migrations within a specified period, offering flexibility for any unforeseen adjustments.

Post-Migration Steps
Completing the data transfer is a significant achievement, but the process doesn't end there. Several crucial post-migration steps are necessary to ensure your new Squarespace store is fully operational, optimized, and ready to welcome customers.
- Thoroughly Review and Test Your Squarespace Store:
- Content Verification: Meticulously check all product listings, ensuring SKUs, variants, categories, descriptions, and pricing are accurate.
- Customer Data: Verify customer accounts, order history, and coupon codes for accuracy.
- Checkout Process: Conduct comprehensive tests of the entire checkout flow, from adding items to the cart, through payment gateways, to final order confirmation.
- Media & Pages: Ensure all images, videos, and other media files have transferred correctly. Review CMS pages and blog posts for proper formatting and content integrity.
- Update DNS Settings: Once you are completely confident in your Squarespace store's functionality, update your domain's DNS records to point to your new Squarespace site. This action will direct all your online traffic to your newly migrated platform.
- Configure 301 Redirects: Even if the migration tool automatically created 301 redirects, it's vital to double-check them. Pay particular attention to any custom URLs or pages that may have changed during the replatforming process. This step is critical for preserving your SEO rankings and preventing broken links that can harm user experience and link equity.
- Update Internal Links and Marketing Materials:
- Internal Site Links: Ensure that all internal links within your Squarespace site correctly point to the new page structures.
- External References: Update any external links that still point to your old BigCommerce store, including those on social media profiles, advertising campaigns, and email signatures.
- Inform Your Customers: Proactively communicate with your customer base about the replatforming. Highlight any new features, improvements to the shopping experience, or changes they might encounter.
- Monitor SEO Performance: Continuously monitor your search engine rankings and website traffic using tools like Google Search Console. Be prepared to address any unexpected drops in performance promptly.
- Consider Recent Data Migration: If there were new orders or customer registrations on your BigCommerce store during the period while your DNS was propagating, consider utilizing a Recent Data Migration Service. This ensures that any latest updates are transferred to your Squarespace store, preventing data loss during the transition phase.
