Open Source Document Management System | OpenKM

Hello
I have a question about migration. I have version( 6.2.1 (build: 7659))
I follow this instruction http://wiki.openkm.com/index.php/Migrat ... 1_to_6.2.2
I understand everything up to the point Run from your preferred SQL client these queries:
Is there possible write detail instruction how do it?

Thank you for any advice

Do you use mysql or embeded database ( have you done any change on database configuration which comes by default with openkm ? )
