"attforblock" to "attendance":
- updated itemmodule field in the grade tables
- updated role_capabilities table to preserve old capabilities
- deleted old data from capabilities and role_capabilities tables
Using multiple table as x in the first section of an UPDATE is specific
to mysql "UPDATE {attendance_statuses} AS sta,{attforblock} AS att SET
sta.attendanceid=att.id WHERE att.course=sta.courseid"; is now
"UPDATE {attendance_statuses} SET attendanceid={attforblock}.id FROM
{attforblock} WHERE {attforblock}.course=courseid";
