Renaming the File Attachments from Old Jira Version
After migrating from Jira Server to Jira Cloud, some attachments are broken due to different format of the file name in old Jira version.
This usually happens when Jira Server was running Jira 4.2 or earlier, then upgraded the version to the latest version.
In older version of Jira, the attachments are named as id_filename (Jira 4.2 and earlier). However, attachments are named only with IDs on the latest version of Jira (including Jira Cloud).
Even after upgrading Jira to the latest version, the old attachments remain with the old formatting,id_filename
