With the new migration app "Migrate Your Data" the logic from the migration tool changed. The migration templates from new and old apps are identical, but the behavior is completely different. Within the old app each file is separated and will be processed one by one. With the new app all the data will be stored in staging tables and the complete content will be executed.

When product has been extended to plant, related data has been stored in staging table. When uploading second file to extend product to storage locations in the same migration project, error message "instance already exists in the table" will occur.

Extend the product to the plant and storage location simultaneously with one "Product - extend existing record by new org levels" migration template.
