Forum .LRN Q&A: Re: Importing, Managing and Delivering Courses Using IMS Specifications out for Testing!

The advantage of versioning courses is that if you have metadata attached to course elements that you have added, that metadata won't be lost if a revised version is uploaded. If you simply delete the course, the comments, ratings, viewing history, etc for that course will be lost.

From that standpoint I think versioning is quite valuable and something I would certainly prefer to see.

Not to mention that I think it would be faster to version than to delete and re-upload.
