PrestaShop to Shopify Migration with Custom Data Mapping – Five Star Jewelers

Migrating from PrestaShop to Shopify posed significant technical challenges due to fundamental differences in how the two platforms handle data structures. To address this, WebDesk Solution engineered a series of robust custom scripts and utilized a secure Linux-based temporary server to run the migration while protecting data integrity throughout.

We developed scripts to extract critical datasets from PrestaShop, including products, categories, customers, and order histories. This data was first staged on a Linux server for cleansing, validation, and transformation to match Shopify’s import-ready formats. Our team implemented multiple layers of validation logic to detect and eliminate duplicate or malformed entries, resolve field mapping inconsistencies, and ensure relational data-such as customer orders-remained intact. Each piece of data was manually checked, cleaned, and tested so there were no discrepancies.

Tech Stack & Execution Environment:

• Server Environment: Temporary Linux-based cloud server for data processing
• Scripting Language: PHP and Python for data extraction and transformation
• Database Layer: CSV-based intermediate storage with checksum validation
• Integration Points: Shopify Admin API for importing cleaned datasets

Key Technical Highlights:

• Migrated 100% of product catalog with titles, descriptions, images, tags, and collections
• Converted and stored PrestaShop order IDs into Shopify order notes for tracking continuity
• Migrated products with more than three options and sold them through the step-by-step option selector (Solution 2)
• Sanitized and imported every customer record; issued password reset emails post-launch

By developing a fully controlled, script-based migration process, we avoided the pitfalls of third-party tools and ensured a high-fidelity transfer of legacy data into the Shopify ecosystem. This solution laid the foundation for a smooth platform transition, enabling Five Star Jewelers to retain historical insights, uphold customer trust, and maintain operational continuity on day one of their new Shopify store.

Migrating from PrestaShop to Shopify is never a plug-and-play task-it’s a meticulous, multi-phase transformation. For Five Star Jewelers, WebDesk Solution designed a full-stack migration strategy that combined deep platform knowledge, hands-on scripting, and an understanding of operational dependencies. We began by auditing all PrestaShop modules, identifying legacy plugins, SEO assets, product types, and customer data structures that needed to be restructured for Shopify’s architecture. The migration process included careful staging, sandbox testing, and validation checkpoints at each milestone.

We avoided third-party auto-migration tools, opting instead to build our own suite of scripts to extract, transform, and import key data like products, customers, categories, and order histories. This allowed us to address Shopify’s platform nuances-such as variant limitations, metafield mappings, and collection structures-at a granular level. The end result was a smooth transition with zero data loss, full platform functionality, and a clean break from PrestaShop’s technical debt. This approach laid a stable, future-proof foundation for long-term eCommerce scalability on Shopify.

This migration was complex because Five Star Jewelers relied on PrestaShop-specific data structures, customer account behavior, pricing logic, and product relationships that did not map directly to Shopify’s architecture.

Key deliverables:

• Custom PHP and Python scripts extracted products, categories, customers, and order histories from PrestaShop.
• Data was staged on a temporary Linux server for cleansing, validation, and transformation into Shopify import formats.
• CSV-based intermediate storage used checksum validation before the Shopify Admin API imported the cleaned datasets.
• PrestaShop order IDs were stored in Shopify order notes to keep order tracking continuous.
• Result: 100% of the product catalog moved with its titles, descriptions, images, tags, and collections.

To navigate Shopify’s limitation of only three product options per product, we designed an elegant, step-by-step selection interface using conditional logic. Rather than overwhelming users with all options at once, customers would select one attribute (e.g., chain length), then be guided to the next relevant choice (e.g., metal type, then gemstone). This allowed us to simulate a deeper level of customization without breaking Shopify’s structural rules. The UX remained clean, intuitive, and true to Five Star’s luxury positioning-all while ensuring backend simplicity and compatibility.

Key deliverables:

• Shoppers choose one attribute, such as chain length, before being guided to the next relevant choice.
• Conditional logic sequences the choices, for example metal type first and then gemstone.
• The interface simulates deeper customization without breaking Shopify’s three-option structural rules.
• Result: products with more than three options were migrated and are sold through the selector.

We rebuilt Five Star’s complex product groupings by leveraging Shopify’s tags, metafields, and custom collection logic. Each product was tagged to belong to specific “virtual” bundles or themed collections, such as matching earrings and necklaces or seasonal gifting sets. Related products were also linked using custom-coded blocks within the product detail page template. Though Shopify lacks parent-child relationships natively, our solution delivered the same outcome-curated pathways for customers to discover complementary products and increase basket size.

Key deliverables:

• Shopify tags, metafields, and custom collection logic rebuilt Five Star’s complex product groupings.
• Products were tagged into “virtual” bundles such as matching earrings and necklaces or seasonal gifting sets.
• Custom-coded blocks in the product detail page template link related products.
• Result: curated pathways help customers discover complementary products and increase basket size.

Customer data was validated and cleaned using our custom scripts prior to import. We migrated every customer record with its name, address, email, and past orders. Post-launch, we triggered a branded password reset campaign using Klaviyo to help customers regain access securely and confidently. The reset emails included direct support links and FAQ content to minimize confusion. This helped Five Star retain customer loyalty while meeting both technical and privacy-related constraints around password encryption.

Key deliverables:

• Customer data was validated and cleaned with custom scripts before it was imported into Shopify.
• Every customer record moved with its name, address, email, and past orders.
• A branded Klaviyo password reset campaign ran after launch so customers could regain access securely.
• Reset emails included direct support links and FAQ content to minimize confusion.
• Result: Five Star retained customer loyalty while meeting the technical constraints around password encryption.

Using Shopify’s customer tagging and automated discount capabilities, we recreated group pricing logic for VIP or wholesale customers. Price lists were managed through Shopify Plus-compatible discount rules, and advanced sorting (e.g., sort by gemstone or popularity) was achieved using custom collection templates and metafields. While not a one-to-one match with PrestaShop, our solution provided a seamless experience for both admin users and customers-preserving personalized pricing strategies and enabling strategic product display for upselling opportunities.

Key deliverables:

• Customer tagging and automated discounts recreated group pricing logic for VIP or wholesale customers.

• Advanced sorting, such as by gemstone or popularity, used custom collection templates and metafields.
• Result: personalized pricing strategies were preserved for admin users and customers, though not one-to-one with PrestaShop.

We translated the Five Star aesthetic into a performance-optimized Shopify theme by rebuilding key design elements using Liquid, HTML5, and CSS. Interactive banners, promo sliders, and iconography were adapted to align with Shopify’s frontend constraints without sacrificing visual quality. We also made use of Shopify Sections to provide Eddie and Fannie’s team with easy drag-and-drop content editing. Every visual asset was re-optimized for speed and responsiveness, resulting in a mobile-first, high-converting design tailored to luxury shoppers. Some components were redesigned from scratch where they could not be carried over from PrestaShop.

• Shopify Sections give the Five Star team drag-and-drop content editing.
• Result: every visual asset was re-optimized for speed and responsiveness in a mobile-first design.

We staged the entire Shopify build on a private development domain while keeping PrestaShop operational. Once the Shopify store was finalized, tested, and SEO-mapped, we conducted a soft launch with a controlled DNS switch-over. Redirects were preloaded, caching settings were verified, and real-time analytics were monitored for anomalies. This “parallel migration” strategy was built to keep the customer experience uninterrupted and orders flowing during the transition.

The plan relied on comprehensive testing, detailed staging environments, careful DNS planning, and post-launch support, and every interaction from homepage to checkout was validated before and after the switch.

Key deliverables:

• The entire Shopify build was staged on a private development domain while PrestaShop stayed operational.
• The finalized store was tested and SEO-mapped before a soft launch with a controlled DNS switch-over.
• Redirects were preloaded, caching settings were verified, and real-time analytics were monitored for anomalies.
• Result: the Shopify Plus store went live on August 15, 2023 through a controlled DNS switch-over.

We conducted a comprehensive SEO audit before the migration, mapping every critical URL from PrestaShop to a corresponding Shopify path. 301 redirects were implemented site-wide, including for top landing pages and blog posts. Meta titles, descriptions, and image alt texts were carried over via CSV and verified post-import. Post-launch, we used Google Search Console and Ahrefs to monitor crawl errors and page indexation. In the three months after launch, site visits were 15% higher than in the three months before.
