By unlinking paired issues, the synchronization information as well as the sync info panel will be removed from two synced issues.  

This can be helpful when, for example, you accidentally synced the issues or because you moved an issue to a different project. 

How to unlink paired issues

You can find the menu entry for unlinking paired issues in the menu (•••) in the top right corner when you are viewing a single synchronization. If it's disabled, make sure that your synchronization is stopped. 

  1. Choose from which project you want to select issues. Note: in a distributed configuration you are not able to choose a project. You can only search in the project on your own instance.

  2. Add a JQL statement to select the issues you want to unlink. You can verify your query and/or run it in Jira search to check which issues are selected. When clicking "Next", the query will be checked on the correctness.
  3. Read the summary carefully and if everything is correct, click on 'Unlink issues'. The process to unlink paired issues will start.
