OpenCart Product Reviews Migration to Shopify

Last updated August 2026

A technical guide to handling product reviews migration when migrating from OpenCart to Shopify. This covers what transfers, what does not, the specific risks for OpenCart stores, and the recommended approach.

OpenCart-specific considerations

When migrating product reviews migration from OpenCart, the following platform-specific aspects must be considered:

Data model implications

OpenCart's data model stores this information differently than Shopify. In OpenCart: oc_order with product, total, history, and shipment tables.

Can Shopify's Store Migration app handle product reviews migration?

What transfers

• Review text content
• Rating values (stars/numeric)
• Review author name
• Review date
• Verified purchase status

What does NOT transfer

• Review images/photos (rare, most platforms)
• Review helpfulness votes
• Review replies / merchant responses
• Review approval status in some cases

Specific risks for OpenCart stores

• Shopify does not have a native product reviews system
• Review app data models differ significantly
• Review-to-product associations can break if product IDs change
• Some review apps have import limits on free plans
• Duplicate reviews if migrating to a new review app

Recommended approach

Choose a Shopify review app (Judge.me, Yotpo, Stamped, Loox). Export reviews from the source platform as CSV. Map fields to the review app's import format. Import reviews, ensuring product references are correct. If using WooCommerce Product Reviews Pro or similar, check if the Shopify review app offers a direct migration path.

Exporting product reviews migration data from OpenCart

• OpenCart Admin CSV export (via extensions)
• OpenCart API
• MySQL database export
• Third-party migration tools

Technical notes

• WooCommerce reviews are WordPress comments with comment_type='review'
• Magento reviews in review + review_detail tables
• Judge.me and Yotpo offer WooCommerce-to-Shopify review migration
• Some review apps support CSV import with product handle mapping
• SEO: review rich snippets need re-implementation
• Rating counts may reset in Shopify if using a new review system
