A Blackboard content conversion tool is available. It was designed to migrate Blackboard 6.1 to Moodle 1.4+ - it may be possible to make it work with other versions.
According to Michael Penney in the forum discussion Migrating 10000 students from Blackboard to Moodle?
- "It works pretty well with a couple of caveats:
- 1) It doesn't import all Blackboard question types: at CSU H, we wrote an essay question type and a 'rendered match' question type and a BB pool importer, we'd like to work with SF and others to get our qtype importer into theirs.
- 2) SF's tool is designed to make you think about your course when you import it and redesign it. That is a nice idea, however it can be pretty time consuming when you have hundreds of documents in a course (<rant>Blackboard's poor content development tools encourage what I call the 'datadump' course format, instead of delivering information in an effective elearning tool like Moodle's lesson, with BB folks tend to post hundreds of office documents and then massive quizzes about them</rant>)."
