Worked on enhancing data migration reliability in the shopware/SwagMigrationAssistant repository by improving the OrderConverter component. Focused on ensuring that migrated orders have accurate primaryOrderDeliveryId and primaryOrderTransactionId fields by automatically populating them from the first delivery and transaction, respectively. This PHP-based backend solution addressed gaps in data completeness, reducing the need for manual post-migration cleanup and supporting more accurate downstream reporting and analytics. Employed unit testing to validate the new logic and maintain code quality. The work targeted a specific migration issue, demonstrating attention to data integrity and usability within the Shopware ecosystem during the migration process.
