Hi,
by Before upgrading from 5.4.5, it's recommended to remove all success jobs. This will expedite the upgrading process. Administration > Scheduled Jobs > Jobs in the top right corner > filter jobs by status = 'Success' > Select All Results > Remove.

or by another way (direct database) : truncate table scheduled_job_log_record
