Top 8 Challenges of Migrating from Drupal 7 to Drupal 10/11

A recent blog post by the Droptica team highlights the top challenges faced when migrating from Drupal 7 to Drupal 10 or 11, offering insights on how to overcome them. Key issues include incomplete website analysis, which often leads to misaligned project estimates and scope expansion. The complexity of migrating content types, especially those with references or custom fields, adds further complications. Scope misdefinition is another common pitfall, with overlooked elements like SEO, accessibility, and security checks impacting project success.

The shift from Drupal 7 modules to newer versions often necessitates finding or creating replacements, while re-theming requires a complete design rebuild due to significant structural changes in Drupal 10/11. Performance optimization is critical as legacy configurations become outdated, and developer skills gaps can delay progress if teams lack experience with the new platforms. User training is also emphasized as a vital yet often neglected aspect, with unfamiliarity causing inefficiencies and higher support demands. The Droptica team recommends thorough audits, precise scoping, developer training, and proactive user support to mitigate these risks and achieve a smooth, cost-effective migration.
