Copy MySQL table and ignore error, rename table

Supposed we have courses_offered table copied from courses_offered_temp:
CREATE TABLE  courses_offered LIKE courses_offered_temp;
I already enter some data in  courses_offered, now I want to copy data from courses_offered_temp.
As some of them may repeat, I need to ignore the error to continue:
INSERT IGNORE INTO `courses_offered` SELECT * FROM `courses_offered_temp` ; 
 INSERT IGNORE is used here.
Rename MySQl table  `course_tutorial_schedule` TO `course_tutorial_schedule_old`:
RENAME TABLE  `course_tutorial_schedule` TO `course_tutorial_schedule_old`;
