Resolving Database Integrity Constraint Violations During eCommerce Data Migration

Encountering an error like "SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry" during an eCommerce data migration can be concerning. This usually indicates a conflict when inserting data into your new store's database.

This type of issue can occur with any platform, including Magento, and often arises from duplicate entries violating unique key constraints in the database.

Here's how to approach resolving this issue during your eCommerce data migration:

  1. Check Error Logs: Examine the detailed error message for clues about the specific table and field causing the conflict. This will help you narrow down the source of the problem.
  2. Identify Duplicate Data: Analyze the data being migrated to identify potential duplicate entries in your source platform.
  3. Clean Up Source Data (Recommended): The best approach is to resolve the data inconsistencies in your source platform before migrating. This ensures a cleaner and more stable migration.
  4. Consult Platform Documentation: Refer to the documentation for both your source and target platforms for information on database constraints and data import best practices.
  5. Contact Support: If you are using Cart2Cart for your eCommerce data migration, reach out to our support team. Provide them with the specific error message and details about your migration setup.
