i will try to be as clear as i can.
so I had moodle running on server "A" and people taking course "A" on that, now I changed to a new server "B" and took the backup of course "A" and restored it but didn't close course "A" on the first server "A" now there are students enrolled and have learned on that server "A". so how can I take that data only and add it to this course because there are also new students enrolled on the new server "B" and learned on it.
