Hi Séverin,
Thanks for your answer.
We are using Moodle 2.6. We will use Moodle 2.7 only for the next academic year (new install).
So, to avoid losing any data on backup/restore I should enable 'legacy logs'. But should standard logs be enabled also? Why? And in which order? 'Legacy logs' first? Dou you know why?
Thank you again,
Best regards,
