Hi my name is Zubair and I have been configuring, deploying and managing moodle for last five years now.
I have seen your requirements, image makes it clear to understand the structure of categories and courses, but unfortunately video didn't play.
Apart from that you need the moodle 2,3 both, I'm not able to understand why, and if for any reason you need, do you exact same copy on both versions.
If you can spare some time and elaborate a bit more about your requirements, I may come up with specific proposal for you.
Looking forward to hear from you and building a new business relationship.
Thanks and Regard s
