Tag1 Consulting Explores D7 to D10 Data Migration for Users and Taxonomy Terms
In part #25 of their Drupal 'Migrations How-to' series written by Mauricio Dinarte, Tag1 Consulting delves into the complexities of migrating user and taxonomy term data from Drupal 7 to Drupal 10. This continuation of their ongoing migration series follows a previous post on file migration, providing essential guidance for organisations planning a Drupal upgrade.
The blogpost, "Migrating Your Data from D7 to D10: User and taxonomy term migrations," highlights critical concepts like entity ID conflicts and high-water mark considerations. Notably, Drupal 7’s user and taxonomy term entities are revisionable by default, while in Drupal 10, only taxonomy term entities retain revision capabilities. To handle ID conflicts, Tag1’s approach involves assessing node and term IDs to properly configure AUTO_INCREMENT
values in the D10 database.
Tag1 also outlines practical steps for migrating users and taxonomy terms, emphasizing the use of Drush commands and the AUTO_INCREMENT
Alter module. They present strategies for managing configuration dependencies, which are crucial in custom migration projects.
To streamline user migration, the post explains how to exclude blocked users and map role IDs between Drupal 7 and 10. For taxonomy terms, it advises merging multiple migration files when vocabularies have no additional fields.
The post offers a blend of technical guidance and best practices, ensuring readers can execute clean, compact, and efficient migrations. Stay tuned for the next installment, which will tackle the challenge of transforming one entity type into another during migration.
