Final Tips for Drupal 7 to 10 Migrations: Debugging, Performance, and AI Assistance

Tag1 Consulting concludes its comprehensive migration series with a blog post by Mauricio Dinarte covering advanced topics in transitioning from Drupal 7 to Drupal 10. This final entry focuses on essential post-migration practices, including debugging techniques, performance optimisations, and preparing for launch by handling broken links and URL changes. Mauricio shares practical guidance on using tools like XDebug, ID map tables, and logging query operations to troubleshoot common migration issues.

The post also addresses how to improve performance during large-scale migrations. Mauricio outlines steps such as disabling unnecessary services, running migrations in sequence or parallel where appropriate, and offloading indexing tasks. He emphasises understanding the impact of migration runners and recommends scripting migrations for greater control. The blog also explains how to optimise local environments and make informed decisions about disabling certain hooks or caches, always with a focus on safe and measurable outcomes.

In the closing section, Mauricio touches on Drupal CMS and the growing role of AI in streamlining migrations. He reflects on demonstrations from recent DrupalCons and highlights how AI-assisted tools are beginning to complement traditional migration methods. While acknowledging AI's potential, he advises caution and stresses the importance of understanding Drupal’s Migrate API in depth. The series wraps up with a reminder that successful migrations rely on preparation, validation, and the careful use of both manual and automated tools.
