Problem

• 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.

Cause

• 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

• Example:

  • Old format:

    

  • New format:
