Thinking about this a little more, I seem to recall unzipping a v1.9 backup file, removing all but the most necessary blocks, or rather, blocks that I knew were not present in v2.x, any user information um.. Role IDs it may have been,, and anything else that did not seem to be essential, zip it back up and then restore. I am pretty sure I took out all the images but finished up having to fix the broken links to a few files, an external link and replaced the images manually. But still, as Ken has mentioned, it remained a "legacy" until I rewrote the course, or rather, created a new course and copy & pasted the course materials. A while ago though.
