My experience with Bpocanada has been extremely delightful. We had the complex task of migrating our portal, www.ilaaka.com, from a 2-year old Drupal version to a current supported version. With over 20,000 nodes, Ilaaka is an Alexa Top 100K site with content being added almost daily since the last two years. With a lot of custom hacks in the code, I was anxious by the magnitude of the task, so when we started the project I had some concerns whether any vendor would be able to pull off this complex migration in a smooth manner.
