FAQ
We try our best to merge fields with as little deviation from the original issue as possible. Unfortunately, due to some limitations of Jira, a few problems remain where we cannot merge all content of existing issues:
Comments and work logs with restricted visibility will not be merged.
Some ServiceDesk and other custom field types can not be merged.
Disabling Sync
You can disable the Merge Agent sync by going to the source ticket, that was merged, opening Merge Agent again and clicking the Disable Sync button.
