Hi everyone,
i have to migrate from Moodle version 2.3.1 to version 3.3.
On the 2.3.1 I have a bunch of courses and related students data (quiz attempts, grades, etc.).
It is safe / supported to do a backup on version 2.3.1 and a restore on version 3.3 ?
There are known compatibility issues or risk of data loss?
Thanks,
Nicola
