Main Part: The Upgrade Process
The following steps outline the recommended process for upgrading your WooCommerce store to version 3.
1. Backup, Backup, Backup!
This cannot be stressed enough. Before making any changes to your site, create a complete backup of your website files and database. This backup will be your safety net if anything goes wrong during the upgrade process. Use a reliable backup plugin like UpdraftPlus, BackupBuddy, or your hosting provider’s backup solution. Ensure your backups are stored in a safe, off-site location (e.g., cloud storage like Dropbox or Google Drive).
2. Staging Environment is Essential
Never upgrade your live store directly. Set up a staging environment – a copy of your website – to test the upgrade process without impacting your customers. Most hosting providers offer staging environments.

3. Check System Requirements
Before upgrading, verify that your server meets the minimum requirements for WooCommerce 3. These include:
You can typically find your current PHP and MySQL versions in your hosting control panel (cPanel, Plesk, etc.) or by using a plugin like “Display PHP Version.”
4. Disable Caching Plugins
Temporarily disable all caching plugins (e.g., WP Super Cache, W3 Total Cache) on your staging environment before starting the upgrade. Caching plugins can sometimes interfere with the upgrade process and cause unexpected issues.
5. Upgrade WooCommerce
Now you’re ready to upgrade WooCommerce in your staging environment. Here’s how:
1. Deactivate WooCommerce: In your WordPress dashboard, go to Plugins > Installed Plugins and deactivate the current WooCommerce plugin.
2. Delete WooCommerce (Optional): If you’re upgrading from a very old version (e.g., WooCommerce 2.x), deleting the old plugin files first can Discover insights on How To Bulk Order Using Woocommerce prevent conflicts. This is optional but recommended. Make sure you still have your backup!
3. Install WooCommerce 3: Go to Plugins > Add New and search for “WooCommerce.” Install and activate WooCommerce 3.
4. Run the Database Update Wizard: After activating the new version, WooCommerce will likely prompt you to run the Database Update Wizard. Follow the on-screen instructions carefully to update your database schema to be compatible with WooCommerce 3. This is a crucial step.
6. Update Themes and Plugins
After upgrading WooCommerce, thoroughly test your website’s functionality. Pay close attention to:
If you encounter any issues, update your theme and plugins to their latest versions. Outdated themes and plugins are often the culprit behind compatibility problems. Contact the theme or plugin developers for support if needed.
7. Code Compatibility (Important for Developers)
If you’re using custom code or a custom theme, review your code for compatibility with WooCommerce 3. Some functions and filters may have been deprecated or changed. Consult the WooCommerce 3.0 upgrade guide for developers for detailed information.
Key changes for developers included:
Here’s an example of how you might update code using the new CRUD classes:
update( $wpdb->posts, array( 'post_title' => 'New Product Title' ), array( 'ID' => $product_id ) );
// New way (recommended)
$product = wc_get_product( $product_id );
$product->set_name( ‘New Product Title’ );
$product->save();
?>
8. Testing and Debugging
Thorough testing is crucial. Use browser developer tools to check for JavaScript errors and PHP notices. Review your server error logs for any warnings or errors related to the upgrade.
9. Update Your Live Site
Once you’ve thoroughly tested the upgrade on your staging environment and resolved any issues, you can proceed to update your live site. Follow these steps:
1. Back up your live site again. This is a final precaution.
2. Put your live site into maintenance mode. Use a plugin like “Maintenance” or “Coming Soon Page & Maintenance Mode” to display a message to your customers that the site is undergoing maintenance.
3. Repeat steps 5 and 6 on your live site: Deactivate, delete (optional), install, and activate WooCommerce 3. Run the Database Update Wizard.
4. Update your theme and plugins on the live site.
5. Remove maintenance mode.
6. Monitor your live site closely for any issues after the upgrade.
Conclusion
Upgrading to WooCommerce 3, while an older upgrade, can still be a worthwhile endeavor for older installations. By following these steps carefully, you can minimize the risk of problems and ensure a smooth transition. Remember that thorough planning, testing, and backing up your data are essential for a successful upgrade.
