| Rules |      * Replace existing link when a link that uses a different link type is added to the same issue    |

## Use Case

## Rules

This workflow supports the following rule:

| Title | Description |
| --- | --- |
| Replace existing link when a link that uses a different link type is added to the same issue |       This on-change rule checks the list of linked issues for a link to an issue that is added as a link when the issue is updated. If the new link is duplicated by a link to the same issue with a different link type, the link is replaced with the link specified in the update.     |
