Thank you.You need to upgrade MySQL on the DirectAdmin server to 5.7 or higher
I did the following steps to doing a re-restoration from cpmove files.
1.- Users deleted from DA web interface (I don't know if there is a bash command to perform a bulk user's delete).
2.- After terminate all accounts (except admin) I tried to restore the backups but an error message prompt on my window regarding about there are no X reseller so, I check the backup folder (/home/admin/all_backups) and I can see files like user.* and reseller.* (I think these are backups generated by DA).
3.- Finally, I remove these files mentioned before and the backup process succesful executed.
4.- Upgrade to mysql 5.7 from 5.5 on step-by-step version
I will update you soon with the results.
