Addressing Entity ID Conflicts in Drupal 7 to 10 Migrations: Practical Solutions

Mauricio Dinarte, Senior Software Engineer and Drupal Migrations Expert at Tag1 Consulting, has shared insights on managing entity ID conflicts when migrating data from Drupal 7 (D7) to Drupal 10 (D10) in a recent blog post. Mauricio addresses a common migration challenge: preventing conflicts in entity IDs, which can arise when IDs in the staging and production environments overlap during incremental migrations. 

In episode #23 of the Migration How-To series published by Tag1 Consulting, Mauricio Dinarte presents two primary strategies for avoiding these conflicts: not reusing entity IDs from D7 or adjusting auto-increment values in D10. The post details a custom approach for manually setting auto-increment values and introduces the AUTO_INCREMENT Alter module, a tool that simplifies the alteration of auto-increment values across content entities. 

Mauricio’s guide highlights both technical solutions and the importance of effective communication to minimize friction and data loss, ensuring a smoother migration for development and editorial teams alike.
