moodlebox-rg Their are a lot of teachers who try to sychronize the data of their students in two Moodle platforms.
First of all you need exactly the same user accounts in the courses you want to use. In the best case you take a course from your official Moodle platform. You need to be a manager in your official Moodle to work with the users accounts. Save the course as a "backup with user accounts". Then you should "restore the course with user accounts" in your MoodleBox. This process will generate all user accounts of your course into the MoodleBox ... all students and all teachers. You will get an error if any person has the same username and a different email address!
When you imported all your users into the MoodleBox you need to set new passwords. During the import all old password are changed to unknown password so you need to set new ones. You can set these passwords manually for every person but you also can do it with a csv file. Download a user list from the MoodleBox. Set new password in the list and upload the list again.
Now every user can log into the MoodleBox with his normal username and with the new password. All users should change their passwords so nobody knows them. Now every user can use the official Moodle plattform and the MoodleBox. To be able to synchronize both platforms nobody is allowed to change his email address only in one platform! Both platforms need to have exactly the same username, firstname, lastname and email address. Otherwise you can't restore a activity backup from the MoodleBox into the official platform.
When you want to start a new activity with your students you must decide if you want to start it in the MoodleBox. You can't work with this activity in both platforms. If the students complete the activity in the MoodleBox you can backup the activity in the MoodleBox with all user data and you can restore the activity into your course in the official Moodle. All user data will be transported to the official Moodle ... all entries from forum, wiki and glossar, all grades and all badges. But remember that you will get a new forum, a new wiki and a new glossar in your official Moodle. The entries will not be integrated into the present forum, wiki or glossar.
I think it will no problem to try this with your students.
