In early 2009, it was determined that the Archdiocese of Saint Louis needed to upgrade its website, mostly for security concerns. After investigating a move from Joomla 1.0.x to Joomla 1.5.x, the Archdiocese determined it would be more cost effective and a more future proof decision to migrate the over 49 individual Joomla sites that comprised www.archstl.org into a single Drupal installation.
This upgrade/migration provides many benefits, not the least of which are a better end-user experience, a better administrative experience, and much improved page load and search indexing performance. In addition, Drupal's structure and content presentation provide much greater flexibility in design and information structure, as well as SEO (search engine optimization) than other popular CMS frameworks that were investigated.
The decision was made early on to partner with a development company that would help with the content migration and initial site buildout. Theming would be done in-house. We chose to partner with Palantir.net, a web development company located in Chicago, IL. After Palantir completed initial site work, I went up to meet them, and also attended my first DrupalCamp (Chicago); Chicago has a much more vibrant Drupal community than St. Louis... but perhaps that will change at some point!
After nearly a year's worth of planning and development, the Archdiocese launched its upgraded website on February 22, 2010.
