Shopware 5 to 6 Migration Blocked? Fix the SwagMigrationTimezone Error

Community Insight: Addressing the 'SwagMigrationTimezone' Error in Shopware 5 to 6 Migrations

Migrating from Shopware 5 to Shopware 6 can sometimes hit unexpected roadblocks. A recent discussion in the Shopware forum highlighted a critical issue preventing the migration process from starting: a '404 – Resource not found' error related to the SwagMigrationTimezone API endpoint.

The core problem arises because the newer Shopware 6 Migration Assistant expects to query the timezone from the Shopware 5 shop via the /api/SwagMigrationTimezone endpoint. However, many Shopware 5 installations use an older version of the 'Migration Connector' plugin (e.g., 2.3.0 from April 2026) which does not yet provide this specific API interface. This mismatch leads to the migration failing to initialize.

Official Update on the Horizon

A Shopware representative, Benjamin_Hummel, confirmed that an official update is imminent to address this problem. This suggests that a patched version of the Migration Connector will soon be available through official channels, resolving the issue for future migrations.

Immediate Workarounds for Blocked Migrations

While awaiting the official update, the community has provided two actionable workarounds:

1. Manual Update of the Shopware 5 Migration Connector Plugin

User Tanny provided a detailed guide to manually update the 'Migration Connector' plugin in Shopware 5 using the latest development version from GitHub:

• Download from GitHub: Get the latest SwagMigrationConnector from the GitHub 'trunk' branch: GitHub - shopware/SwagMigrationConnector. Click 'Code' and then 'Download ZIP'.
• Rename Folder: Unpack the ZIP file. Rename the extracted folder (e.g., SwagMigrationConnector-trunk) to SwagMigrationConnector.
• Adjust Version (if 2.3.0 is installed): If you already have version 2.3.0 installed, open the plugin.xml file within the SwagMigrationConnector folder and change 2.3.0 to 2.3.1. This ensures Shopware recognizes it as an update.
• Clean Up (Optional): For a leaner package, you can delete developer-specific files (e.g., Tests, .github, Makefile) as indicated in the .sw-zip-blacklist file before zipping.
• Re-zip and Upload: Zip the modified SwagMigrationConnector folder again and upload it via the Shopware 5 Plugin Manager.

Important: Always create a full backup of your Shopware 5 shop before attempting manual plugin updates.

2. Temporary API Mock for Timezone Data

User R4M offered a quick, albeit 'not clean,' temporary solution by creating a dummy API endpoint in the Shopware 5 root directory to provide the expected timezone data:

• Create Directory Structure: In the root directory of your Shopware 5 shop, create a folder named api, and inside that, another folder named SwagMigrationTimezone.
• Create index.php: Inside the SwagMigrationTimezone folder, create an index.php file with the following content:

This temporary endpoint will respond with a hardcoded timezone, allowing the Shopware 6 Migration Assistant to proceed past the initial timezone query error. R4M emphasizes using this at your own risk, as it's a quick fix rather than a robust solution.

Community Frustration and the Path Forward

The discussion also highlighted a degree of frustration among developers and merchants who are keen to migrate to Shopware 6 but are blocked by such issues. The sentiment is clear: a smooth migration path is crucial for Shopware 6 adoption, especially given the number of Shopware 5 shops still in operation.

These community-driven solutions provide essential relief for those facing immediate migration blockers. While the official update is the preferred long-term solution, these workarounds demonstrate the power of the Shopware community in overcoming challenges.
