We are in the beginning stages of researching Moodle. I have found lots of information and it has been very helpful. What I haven't found is an institution of our size who has converted over to Moodle from Bb.
We are currently on Bb 8 Enterprise (or Learn whatever it is now) so we have the community system (about 90 sites) and we have just implemented the Bb Content Sytem to our instructors. For FA 09 we currently have over 1,900 course active, with over 800 instructors, and over 19,000 students (over 6000 total courses on the system with materials and over 84,000 user accounts (user accounts have to be cleaned up still)). I haven’t been able to find an institution that has transitioned that many sites and users or has the content system in place and completed the transition.
Any info anyone could provide would be great.
