Why Q4 2026 Is the Most Expensive Time to Migrate Drupal

FAQs

 

Drupal 10 security support ends on December 9, 2026. After that date, any newly discovered vulnerabilities will not receive patches, leaving sites exposed. For enterprises subject to GDPR, HIPAA, or PCI-DSS, operating on unsupported software crosses from a technical gap into an active compliance risk.

 

It depends on your starting point. Drupal 7 migrations, which are full rebuilds, not upgrades, typically require 7 to 12 months, depending on site complexity. Drupal 10 to 11 upgrades are less technically complex and generally take 2 to 4 months. 

 

Industry research shows enterprises spend 60–80% of IT budgets maintaining legacy systems. Separately, estimates suggest developers lose up to 42% of their time, roughly two full workdays per week, managing technical debt.

 

The recommended starting point is a migration readiness audit; from there, the priority is selecting and signing a migration partner in Q1. Organizations that haven't started that process by mid-year are unlikely to complete migration before the December deadline.
