Released in 2007, Drupal 5 was once a robust and flexible content management system (CMS), but today it is obsolete—unsupported, insecure, and incompatible with modern technologies.
Migrating a Drupal 5 website to a modern version of Drupal (such as Drupal 9, 10, or later) is not a simple upgrade.

Two of the most critical concerns for businesses undertaking this journey are timeline and cost.
Understanding how long the migration will take and how much it will cost is essential for planning, budgeting, and minimizing business disruption.
