But it worked perfect for you only! The question was about ALL users data downloading INCLUDING passwords. But the linked docs don't answer the question, alas!
I need, e.g., to download all the users from 1-st system and upload this file to 2-тв one. Why? I have the mirrow systems and would like users to be registered themselves once in 1-st moodle only. Then Ill be ready to transfere their accounts to another system. How to do this?
