BigCommerce to OpenCart Migration

Choose Your BigCommerce to OpenCart Migration Method

Choose the approach around the records you need to retain and the work your team can manage. A product-only import has a different scope from moving customer accounts, historical orders, reviews, manufacturers, tax records, and coupons.

Automated Migration is the primary workflow on this page. Use expert review for records owned by BigCommerce apps, custom fields, or integrations and for structures outside the listed scope. Document those requirements before choosing a service so the quotation describes the actual work.

Prepare and Back Up Your BigCommerce Store

Start with an inventory of the source data. Record the numbers of products, categories, customers, orders, manufacturers, taxes, coupons, and reviews. Identify information stored by BigCommerce apps, custom fields, external systems, or custom storefront components.

• Keep source exports and a target backup. Retain current BigCommerce exports and a record of the store settings your team will recreate. Back up the OpenCart files and database before importing data or clearing target records.
• Review data quality. Identify duplicate SKUs, obsolete records, broken images, and inconsistent descriptions. Agree on any cleanup before editing production data.
• Prepare OpenCart. Confirm the version, hosting, database, storage, SSL, and extension compatibility with your developer or hosting provider. Test the installation before connecting it.
• Document access. Arrange the access required by the connection instructions. Give the source only the permissions needed to read the migration data.
• Inventory apps and integrations. List fulfillment, search, subscriptions, wholesale, accounting, and other workflows. Choose OpenCart replacements and assign configuration work to your team.
• Record launch dependencies. Keep the current URLs, domain settings, payment providers, shipping methods, and email configuration available for the launch checklist.

Run an Automated BigCommerce to OpenCart Migration

Step 1. Connect BigCommerce and OpenCart

Create a migration in your LitExtension account and enter the Source and Target Cart types and URLs. Follow the connection instructions presented for your selected stores. For an open-source installation, the setup uses the LitExtension connector; arrange help from your developer if file access is managed by another team.

Confirm that both connections succeed before selecting records. Keep the OpenCart target available for testing and avoid switching the production domain at this stage. Check that the migration is pointing to the intended target installation before proceeding.

Step 2. Select Records and Additional Options

Select the entities you want to transfer. Products include the shared category fields. Customers, orders, manufacturers, taxes, coupons, and reviews have their own supported fields, shown in the data section below.

Review each option against your launch plan. Select Preserve Order IDs to retain the source order identifiers. Use 301 redirects to send old URLs to the corresponding OpenCart pages. Description-image migration handles images embedded in product and category descriptions, separately from the ordinary product and category image fields.

Clear Target Data removes existing records for the selected entities before transfer. Check your backup and decide which target records must remain before selecting it. Do not use this option as a substitute for reviewing duplicate data or testing the migration configuration.

Step 3. Run and Inspect a Free Demo

Use the Demo to examine a sample of your selected data in OpenCart. Compare names, descriptions, SKUs, prices, stock values, images, category assignments, customer details, and historical order totals with BigCommerce.

Check representative reviews, manufacturers, coupons, and tax records as well as ordinary product records. Document any discrepancies and resolve the relevant mapping or configuration questions before running the complete transfer. A Demo lets you review the data result; checkout and extension testing remain separate launch tasks.

Step 4. Start Full Migration

Once you approve the Demo result, start Full Migration with the agreed data and options. The transfer runs on LitExtension’s servers, so you can close your browser while it continues. Track progress in your account and inspect the target when the transfer completes.

Keep a record of new BigCommerce orders, customer registrations, and catalog edits made during the move. An initial transfer is not continuous synchronization. Plan the final data update and domain switch together so the launch includes the required recent activity.

How BigCommerce Data Maps to OpenCart

BigCommerce variants and OpenCart options need a defined representation before they are included in a custom project. Send examples of variant structures, SKU rules, prices, and stock to the migration team. The standard product fields listed below do not promise a transfer of every variant structure.

CMS pages, blog posts, themes, app functionality, payment credentials, and shipping configuration are outside this standard data transfer. Plan content recreation and OpenCart configuration separately. For app-owned data, custom fields, or page-builder content, request a review of the actual source records and intended destination before agreeing on additional work.

Migration Cost and Timeline

Use your product, customer, and order counts to estimate the migration cost. The selected records, images, options, source and target setup, and any separately agreed custom work determine the final scope. Use Estimate Migration Cost for this route.

Preparation, transfer, validation, and launch are separate stages. Allow time for reviewing the Demo, correcting data issues, configuring the OpenCart storefront, and testing checkout. Use the Demo and your store inventory to plan the work instead of relying on a fixed completion-time promise.

Post-Migration Checklist: BigCommerce to OpenCart

Check Migrated Records

• Compare source and target counts for the selected entities.
• Inspect product text, SKUs, stock, prices, images, metadata, attributes, and category assignments.
• Review customer names, emails, billing addresses, and links to historical orders.
• Compare historical order IDs, dates, statuses, totals, comments, and addresses.
• Inspect manufacturers, tax records, coupons, and reviews.

Complete the OpenCart Setup

• Configure the target theme, navigation, extensions, email delivery, and integrations.
• Set up payment providers and shipping methods; verify tax behavior against your business requirements.
• Recreate CMS pages and other content outside the standard transfer.
• Test product pages, search, cart, and checkout on desktop and mobile.

Review URLs and Search Visibility

• Map important old URLs to relevant OpenCart destinations and test the redirects.
• Review product and category meta titles and descriptions, internal links, canonical URLs, and indexing settings.
• Submit the target sitemap and monitor crawl errors and indexing after launch.

Update Recent Data and Launch

Before switching the domain, account for records created or changed in BigCommerce after the initial transfer. Recent Data Migration transfers new records; Smart Update handles supported changes to existing records; Re-migration reruns a transfer. Confirm the records, eligibility, and current service terms for the operation you need.

Approve the migrated data, checkout, redirects, and recent-data result before the domain switch. Monitor new orders, payments, customer access, and error reports after launch. Report migration discrepancies with example source and target records so support can investigate the specific issue.
