HCL Technologies moved their website from ASP to Drupal in order to improve their online presence, user experience, and search functionality while reducing maintenance costs. They selected Drupal due to its abilities for content management, search engine optimization, and security through frequent updates as an open source platform. The transition faced challenges with content migration and performance optimization but provided benefits like enhanced content discovery, social sharing, and SEO friendliness. The project was successful and won an award with a small dedicated team.
