Hi
Given that there's almost no chance of getting your 'backwards' migration, there are still things you might do depending on the actual content of your courses.
e.g. If you have tests with banks of questions, you could export the questions in a format such as GIFT and reimport them into 1.9. You'll then need to retype instructions and labels (copy and paste) etc. Better than nothing at all. You'll have to tell us what sort of course content you have for more specific help.
