We've been working with the GW Law School to convert their existing ASP.NET-based Sharepoint public website to an open source solution. The decision was made to utilize the Drupal 7 Content Management System. The DC-based Law School wanted to reduce their Microsoft dependency while simultaneously coming inline with the Drupal community that exists at GWU.
We worked together to migrate content, alter content templates, change workflow, and convert MS SQL data to MySQL records as structured for Drupal 7. The ongoing project, as of early 2015, connects the GW Law School to the Drupal community within GWU's business units.
