Fix Shopware 5 to 6 Migration 'SwagMigrationTimezone' Error

Migrating your e-commerce store from Shopware 5 to Shopware 6 is a significant step towards modernizing your online presence. However, the path to a successful migration isn't always smooth. One common roadblock that many merchants and developers encounter is the dreaded '404 – Resource not found' error related to the SwagMigrationTimezone API endpoint. At Migrate My Store, we understand the frustration these issues can cause, and we're here to guide you through resolving them.

Understanding the 'SwagMigrationTimezone' Migration Error

The core of this problem lies in a version mismatch between your Shopware 6 Migration Assistant and the 'Migration Connector' plugin installed on your Shopware 5 source shop. As the Shopware 6 Migration Assistant evolves, it introduces new functionalities and expectations for data retrieval from the Shopware 5 environment. Specifically, newer versions of the SW6 assistant attempt to query the timezone information from your Shopware 5 shop via the /api/SwagMigrationTimezone endpoint.

However, if your Shopware 5 installation is running an older version of the 'Migration Connector' plugin (for instance, version 2.3.0 from April 2026, as noted in the community discussions), this particular API interface might not yet be implemented. When the SW6 Migration Assistant makes the request, the SW5 shop responds with a '404 – Resource not found' error, halting the migration process before it can even begin. This prevents the necessary data mappings from being generated, effectively blocking your migration.

Official Update on the Horizon

The good news, as confirmed by Shopware's Benjamin_Hummel, is that an official update is imminent to address this specific problem. This indicates that Shopware is aware of the issue and is actively working on providing a patched version of the Migration Connector plugin through official channels. Waiting for and installing this official update is always the recommended approach, as it ensures stability, compatibility, and ongoing support.

Immediate Workarounds for Blocked Migrations

While awaiting the official release, we understand that some migrations cannot wait. The Shopware community has identified and shared effective workarounds to help you proceed. Please remember to always perform a full backup of your Shopware 5 shop before attempting any manual modifications or updates.

1. Manual Update of the Shopware 5 Migration Connector Plugin

This method involves manually updating your Shopware 5 'Migration Connector' plugin to the latest development version available on GitHub. This version often includes fixes that haven't yet made it into the official Shopware Store release.

Step 1: Download from GitHub: Navigate to the official SwagMigrationConnector GitHub repository: GitHub - shopware/SwagMigrationConnector. Click on the 'Code' button and then select 'Download ZIP' for the 'trunk' branch.
Step 2: Unpack and Rename: Extract the downloaded ZIP file. You will likely find a folder named something like SwagMigrationConnector-trunk. Rename this folder to simply SwagMigrationConnector.
Step 3: Adjust Plugin Version (Crucial for Update Recognition): If you already have version 2.3.0 of the Migration Connector installed, Shopware 5 might not recognize the new version as an update. To force recognition, open the plugin.xml file located within your newly renamed SwagMigrationConnector folder. Find the line 2.3.0 and change it to 2.3.1 (or a higher, non-existent version number).
Step 4: Re-zip the Plugin: Compress the entire SwagMigrationConnector folder back into a ZIP file.
Step 5: Upload and Install in SW5: Log into your Shopware 5 backend. Go to the Plugin Manager, upload your newly created ZIP file, and then install/activate the updated 'Migration Connector' plugin.
Optional: Clean Up Development Files: Before zipping, you can optionally delete unnecessary development files (like Tests, .github, Makefile, etc. – refer to the .sw-zip-blacklist file in the repository for a list of files to exclude). This keeps your plugin package lean.

Disclaimer: This method involves using a development version and is without guarantee. Always back up your shop before proceeding.

2. Temporary API Endpoint (Use with Extreme Caution)

User R4M proposed a temporary, less conventional workaround. This method involves manually creating a mock API endpoint in your Shopware 5 shop to provide the expected timezone data. While it might allow the migration to proceed, it is not a clean or recommended solution for production environments due to potential security implications and maintenance overhead.

Step 1: Create Directory Structure: In the root directory of your Shopware 5 shop, create a new folder named api. Inside api, create another folder named SwagMigrationTimezone.
Step 2: Create index.php: Inside the SwagMigrationTimezone folder, create a file named index.php.
Step 3: Add Content to index.php: Paste the following code into the index.php file:


This code simply outputs a JSON string with a default timezone. While this might trick the SW6 Migration Assistant into starting, it's a workaround that bypasses the intended plugin functionality. Migrate My Store strongly advises against using this method in a live production environment. It should only be considered as a last resort for testing or development purposes, and must be removed immediately after the migration is complete.


  


Best Practices for a Smooth Shopware Migration
Beyond specific error resolutions, a successful Shopware 5 to 6 migration hinges on a few critical best practices:

  Comprehensive Backup: Always, always, always back up your entire Shopware 5 database and files before starting any migration process.
  Staging Environment: Perform your migration on a staging or development environment first. Never attempt a direct migration on your live production shop.
  Plugin Compatibility: Review all your Shopware 5 plugins. Not all will have direct Shopware 6 equivalents, and some may require manual data migration or alternative solutions.
  Thorough Testing: After migration, rigorously test all aspects of your new Shopware 6 store: product data, customer accounts, orders, payment gateways, shipping methods, search, and checkout flow.
  Consider Professional Help: For complex shops or if you lack the technical expertise, engaging e-commerce migration experts like Migrate My Store can save you significant time, stress, and potential data loss. We specialize in seamless Shopware migrations, ensuring your business continuity.
