I have been working on this as well...I am running moodle 2.1 but would like to upgrade to 2.3
Rather than doing the on-server upgrade (which seems very challenging) I am looking at just starting a new Moodle 2.3 and copying everything in. This should be easy enough for my plugins and theme, but how can I export 1000+ courses and then import them into a new site?
So far I've been unable to get the automated course backup to actually give me the .mbz files in a specific directory as well.
Thank you for your assistance.
