Migrating Media from Drupal 7 to 10: Custom Source Plugins and Best Practices

Staff Reporter

In a recent blog post on Tag1 Consulting, Drupal migration expert Mauricio Dinarte explores how to migrate media content from Drupal 7 to Drupal 10. He emphasizes understanding the source site's media modules, such as Core’s file and image modules, and the YouTube Field module. The migration process varies based on the modules used and the target content model.

Dinarte explains how to prevent entity ID conflicts using the AUTO_INCREMENT Alter module and details the creation of custom source plugins. These plugins retrieve data from Drupal 7 databases, JSON, XML, CSV, and more, utilizing the prepareRow method for data adjustments.

A practical example involves migrating YouTube field data into remote video media entities in Drupal 10. The post also covers extending existing source plugins, such as modifying the d7_file plugin for image migrations. This guide provides essential techniques for developers handling Drupal media migrations.
