The integration offers a one-click option to migrate attachments from JIRA to Hansoft of your synced items. Simply mark and right click the item(s) you want to migrate attachments for and click "Migrate attachments from JIRA to Hansoft". The attachments will now be available in the Hansoft attachment list. See screenshots below.
Note: This is not a syncing of attachments, it is a one time copy of them from JIRA to Hansoft. If additional documents are added on the JIRA side the migration must be run again.
