As a user, I expect and request that all boards use the same information for the epic-story-task hierarchy.

It is unacceptable that different boards use different information to get the connection between stories and Epics:

• the classic boards use a custom field
• the rapid boards use an issue link

The request is to update the classic boards in GH6 to use the same link as the rapid boards.

GHS-6828 (https://jira.atlassian.com/browse/GHS-6828) can be regarded only as a first step to bring things together.

The update procedure would then be the following:

• Update GH
• Find that the Epics in the classic boards are not connected to their stories
• Call the maintenance procedure from GHS-6828

... and have consistent data.

Having to call the Maintenance procedure from GHS-6828 regularly and manually is not an option to users which need to use both board versions:

• A change in the rapid boards would be overwritten
• A change in the classic boards would not take immediate effect on the rapid boards
• Using only one type of board is not acceptable.
