Problem

If an Epic is moved to another project and simultaneous changed to another issue type, existing Stories linked to this Epic is not removed.

• This then affects JQL queries results.

Steps to Reproduce

• Create a scrum project
• Create an Epic (let's say this is SSP-20)
• Add a Story to this Epic
• Confirm the JQL query:

  "Epic Link" = SSP-20
  

  • Note the Story is returned
• Move the Epic, SSP-20 to another project and change the issue type to a non-Epic

Expected Behaviour

As SSP-20 is no longer an Epic and moved to another project, all existing Epic links should be removed.

Actual Behaviour

• Notice that the UI no longer displays any Epic links
• JQL search continues to show that the Epic link exists:

  "Epic Link" = SSP-20
  

• Check the database issuelink table and notice that the link exists in the database

Workaround

• Manually remove the link from the database
• Perform a project re-index
