Migrating from OpenCart to Wix is a strategic move from a self-hosted open-source platform to a website builder. In 2025, with OpenCart's technical management, and Wix's visual website builder with integrated e-commerce, the case for migration has never been stronger.

This comprehensive technical blueprint is designed for store owners, developers, and decision-makers. We will bypass the marketing fluff and dissect the database structures, the exact field mappings, the cost analysis, and the step-by-step execution required to move your data to Wix without losing a single byte.

1. The Strategic Pivot: Why Leave OpenCart?

OpenCart is a powerful open-source eCommerce platform, but it often becomes limiting for businesses that need visual website builder with integrated e-commerce. Moving to Wix opens specific opportunities:

💰 Visual Website Builder

The OpenCart Pain: OpenCart requires self-hosting, server management, and technical maintenance. You're responsible for updates, security, and performance optimization.

The Wix Gain: Drag-and-drop website builder. Create beautiful stores without coding.

🚀 All-in-One Platform

The OpenCart Pain: OpenCart has a smaller extension marketplace compared to major platforms. Limited third-party integrations.

The Wix Gain: Website, blog, and store in one platform. No need for separate tools.

🛠 Easy Management

The OpenCart Pain: OpenCart requires technical knowledge for advanced customization. Limited built-in features compared to hosted solutions.

The Wix Gain: User-friendly interface. Perfect for non-technical users.

⚡ Hosted Solution

The OpenCart Pain: OpenCart requires you to manage hosting, updates, and technical aspects yourself.

The Wix Gain: Fully hosted with automatic updates. No server management required.

2. The Pre-Migration Architecture Audit

Before touching any data, you must map the terrain. OpenCart and Wix speak different data languages.

A. Understanding the Platform Disconnect

OpenCart uses MySQL database with REST API for export. Wix uses API or CSV for data import.

OpenCart Version: Are you on OpenCart 2.x, 3.x, or 4.x? Database structure may differ. Migration tools handle all versions.
Database Access: OpenCart requires MySQL database access or bridge extension. Migration tools use bridge extension for safe data extraction.
Wix Setup: Ensure Wix is set up and ready. Configure API or CSV access if required.
Product Structure: OpenCart products with options map to Wix products. OpenCart's unlimited options may need mapping to Wix's structure.
Images: OpenCart images are in image/ directory. Need to be transferred to Wix's media system.

3. Exact Data Mapping: The Blueprint

This is the most critical section for developers. This is how OpenCart entities translate to Wix. We assume the use of an automated migration tool.

🛍 Product Data Mapping

OpenCart Field (Source)	Wix Field (Target)	Notes & Logic
`product_id`	`Product ID`	Wix generates new IDs. Use SKU for mapping.
`name` (oc_product_description)	`Product Name`	Direct string transfer.
`sku`	`SKU`	Direct mapping. OpenCart SKU at product level.
`price`	`Price`	Direct mapping with currency conversion if needed.
`description` (oc_product_description)	`Description`	HTML content. Images need re-uploading to Wix's media system.
`category_id` (oc_product_to_category)	`Category`	OpenCart categories become Wix categories.
`product_option` and `product_option_value`	`Attributes/Variants`	OpenCart's unlimited options map to Wix attributes/variants. May need consolidation if Wix has limits.

👥 Customer Data Mapping

OpenCart Field	Wix Field	Critical Logic
`email`	`Email`	Unique identifier.
`password` (hashed)	`Password` (on create)	Password migration depends on Wix support. OpenCart uses bcrypt. Migration tool handles conversion if supported, otherwise customers must reset passwords.
`oc_address`	`Address`	OpenCart addresses map to Wix customer addresses.

📦 Order Data Mapping

OpenCart Field	Wix Field	Mapping Logic
`order_id`	`Order ID`	Preserve OpenCart order number in Wix order ID or custom field.
`order_status_id`	`Order Status`	Map OpenCart order statuses to Wix order statuses.
`total`	`Total`	Direct mapping with currency conversion if needed.

4. The Toolkit: Selecting Your Vehicle

You have three vectors of attack for this migration. Choose based on budget and technical capability.

Option A: Automated Cloud Migration (Recommended)

Tools: Shopping Cart Mover, LitExtension, Cart2Cart

Specialized tools that connect via OpenCart bridge extension and Wix API or CSV.

✅ Pros: Handles database complexity, preserves relationships, formats data for Wix automatically.
❌ Cons: Cost scales with data ($200 - $400). Requires bridge extension on OpenCart.

Option B: CSV Import

Tools: OpenCart CSV Export + Wix CSV Import

Export from OpenCart, format for Wix, and import manually.

✅ Pros: Lower cost, direct control.
❌ Cons: Manual work required, may lose some data relationships. Limited to products and categories.

Option C: Custom Development

Tools: OpenCart REST API + Wix API or CSV

Build a custom script using OpenCart REST API and Wix API or CSV.

✅ Pros: Complete control, reusable.
❌ Cons: Expensive ($2,500+), time-consuming. Must handle OpenCart's MySQL structure and Wix's data format.

5. Execution Protocol: Step-by-Step

We will proceed using the Automated Cloud Migration method as it is the industry standard for minimizing downtime.

Phase 1: Environment Preparation

1.1. Prepare Target (Wix):
Set up your Wix store. Complete Wix setup wizard. Configure API or CSV access if required. Do not point your domain there yet. Use subdomain for testing.
Tip: Use password protection or maintenance mode to prevent public access during setup.

1.2. Prepare Source (OpenCart):
Install migration bridge extension on OpenCart. Ensure MySQL database access is available. Keep your OpenCart store live during migration.

Phase 2: The Connection Setup

2.1. Wix Access:
Configure API or CSV access in Wix. Generate API credentials or set up connection method as required.

2.2. OpenCart Access:
Bridge extension connects to OpenCart MySQL database. Migration tool authenticates via bridge extension API.

Phase 3: Migration Execution

Select what to move. Be careful with these specific settings:

Create 301 Redirects: Check this box if using custom domain. It creates redirects from OpenCart URLs to Wix URLs. Without this, your SEO dies.
Migrate Product Options: OpenCart supports unlimited options. May need to consolidate if Wix has variant limits.
Migrate Images: Images are downloaded from OpenCart image directory and uploaded to Wix's media system automatically.
Password Migration: Depends on Wix support. Customer passwords may be migrated if Wix supports it, otherwise customers must reset passwords.

Phase 4: The Full Migration

Launch the process. The migration tool handles OpenCart MySQL extraction and Wix API or CSV import automatically.

Time Estimation: 5,000 products + 10,000 orders usually takes 2-4 hours. Large catalogs migrate efficiently via automated tools.

Phase 5: Post-Migration Cleanup

5.1. Customer Communication:
Notify customers about the migration. They may need to reset passwords depending on Wix password migration support.

5.2. Verify Products:
Check all products migrated correctly. Verify images, prices, and product options. Note any variant limitations in Wix.

5.3. Design & Customization:
Choose or customize Wix theme. OpenCart themes cannot be migrated, but Wix offers its own theme options.

6. Financial Breakdown: Cost of Migration (2025)
