This document summarizes an organization's transition from a proprietary content management system to an open source system using Drupal. It describes how the proprietary system had become expensive to update and maintain. The open source Drupal platform provided more flexibility, security, and an engaged developer community. While the migration was mostly smooth, some challenges remain in developing the Arabic open source community and customizing the new system. Overall, the organization is pleased with becoming less reliant on consultants and more in control of its technology choices and future.
