Restore Backup from FPBX 16 into FPBX 17

In a newly installed FPBX 17 there are several error messages in connection with mysql when restoring the backup of FPBX 16.
I have solved the problem by removing the string - in the first line of the SQL backup files.
Instead of
/*M!999999- enable the sandbox mode */
then reads
/*M!999999 enable the sandbox mode */

By the way, I am very surprised why the Devices.sql file is restored several times as you can see in the error messages.

Enclosed the error messages:
