jazzl0ver / move_attachments.php.patch
Created September 8, 2020 12:49
A dirty hack to move MantisBT attachments to disk by 100 at a time. Might be needed to execute it several times. Useful when there're a lot of attachments out there. Don't forget to raise max_execution_time and memory_limit PHP parameters in php.ini.
