VirtueMart to OpenCart Migration

Migration from VirtueMart to OpenCart: A Detailed Guide

This guide provides a comprehensive, step-by-step process for migrating a store from VirtueMart to OpenCart. A manual migration offers greater control and a deeper understanding of your store’s data. Note that this method is time-consuming and requires a strong understanding of database management.

Step 1: Data Backup and New Store Setup

Before beginning the migration, it’s critical to secure your existing data and prepare the new environment.

Backup Your VirtueMart Store

Create a complete and verified backup of your entire VirtueMart store. This includes both the database (via phpMyAdmin) and all store files (via FTP/SFTP). This backup serves as a safeguard, allowing you to revert to the original state if any issues arise during the migration.

How to backup your VirtueMart store:

• Access to VirtueMart Admin Dashboard.
• Go to Tools > Database Backup/Restore wizard.
• Select “Backup current store database” and click Next to proceed.
• Name the file and directory for the backup.
• Select the tables you want to back up. By default, all tables are usually selected, but you can choose to include or exclude specific ones based on your needs.
• Do not select the option ‘Backup database structure only (no data)’, as this will save only the table structures without any data in the .sql file. You can also back up all shopping cart files and choose to exclude specific files if necessary.
• Click the ‘Backup’ button. The backup will then be saved to the file you specified earlier.
• Finally, click ‘Finish’ to close the wizard.

Note: You need an active FTP connection to download the files. Keep in mind that this may slow down the process.

Install OpenCart

Install the latest stable version of OpenCart on your server. It is strongly recommended to start with a clean installation to prevent conflicts. If you plan to use an existing OpenCart installation, make sure it is fully updated and backed up before proceeding.

For detailed guidance, refer to our step-by-step OpenCart installation tutorial. In summary, the process involves:

• Choosing a Hosting Provider
• Downloading OpenCart
• Extracting Files and Uploading to the Server using FTP
• Creating a MySQL Database and User via cPanel
• Running the Installation Script
• Completing the Installation

This is not a beginner-friendly procedure, so review the instructions carefully and follow each step by step to avoid issues.

Step 2: Exporting Data from VirtueMart

Data must be exported from your VirtueMart database and formatted for use with OpenCart.

Export Database Tables

Use a database management tool like phpMyAdmin to export data from the specific VirtueMart tables you need to migrate. Focus on key entities such as products, categories, customers, and orders. You can export the entire database as a single .sql file, or for more control, export individual tables.

How to export VirtueMart tables with phpMyAdmin:

• Log into phpMyAdmin from your hosting control panel.
• Select the VirtueMart database.
• Go to the Export tab.
• Choose either all tables or only the key ones (products, categories, customers, orders).
• Pick the format: SQL for structure + data, or CSV for easier editing.
• Click Go to download the file.

Format the Data

Once exported, the data should be saved in a CSV (Comma-Separated Values) format. This format is easier to manipulate and review. Tools like Excel or Google Sheets can be used to open and edit the exported data. This step is crucial, as the VirtueMart data structure will not directly match OpenCart’s.

Step 3: Preparing Data & Importing Data into OpenCart

This is the most complex part of the manual migration process, as it requires you to align your exported data with OpenCart’s specific database schema:

• Map Database Fields: Open the exported CSV files and carefully compare the field names (column headers) from VirtueMart to the corresponding field names in OpenCart’s database tables (e.g., oc_product, oc_category, oc_customer, oc_order). Manually rename and reorder the columns in your CSV files to match the OpenCart structure exactly.
• Update File Paths and Images: If you have product images, they must be manually transferred from your VirtueMart server to the appropriate image directory within your new OpenCart installation (typically image/catalog/). After moving the files, you must update the image paths in your CSV files to reflect their new location in OpenCart.
• Clean and Validate Data: Review your CSV files for any inconsistencies or invalid data. This includes checking for correct data types (e.g., ensuring numeric fields contain only numbers) and removing any unnecessary or corrupted data.
• Import via phpMyAdmin: You can use phpMyAdmin to import the prepared CSV files directly into the respective OpenCart database tables. This is done by writing SQL INSERT queries that map the data from your CSV columns to the OpenCart table fields. This method is highly effective but requires a strong understanding of SQL.

After the import is complete, immediately log into your OpenCart admin panel. Thoroughly check that all products, categories, customers, and orders have been imported correctly. Look for any missing information, data mismatches, or formatting errors. It is best to spot-check a random sample of entries to ensure data integrity.

This step can be tricky, especially when formatting data to match OpenCart’s CSV structure. For detailed guidance, read our expert article: Migrate CSV Files to OpenCart.

Step 4: Post-Migration Tasks

Completing the data import is just the first step. The final phase involves configuring and testing your new store to ensure it is fully functional:

Point Domain & Set Redirects:

• Update your domain’s DNS to point to the new OpenCart server.
• On the new server, set up 301 redirects from old VirtueMart URLs to matching OpenCart URLs.
• Test redirects and confirm all pages resolve correctly.

Install Theme and Extensions:

• Select and install a new theme for your OpenCart store. Then, find and install any necessary extensions to replicate the functionality you had in VirtueMart.

Configure Store Settings:

• Go through all of the settings in your OpenCart admin panel. This includes configuring payment gateways, shipping methods, tax rates, and store information to match the previous settings from your VirtueMart store.

Perform a complete end-to-end test:

• Product Display: Ensure products are visible, and all images and descriptions are correct.
• Checkout Process: Run a test order from start to finish to confirm that the checkout, payment, and order confirmation processes work flawlessly.
• Customer Accounts: Verify that customer accounts are accessible and that they can log in and view their order history.
• Functionality: Test all other core functionalities, such as search, contact forms, and email notifications.

Once all checks and tests are complete and you are confident in the store’s performance, you can consider the migration a success.
