Project administrators can choose to either enable or disable QAlity - Test Management for Jira for any of their projects. This can be done via Jira Settings → Apps → QALITY → Settings. Simply toggle the switch on or off for the projects to enable/disable QAlity. This change will only cause the QAlity to stop showing up in the Jira issues, but no data will be removed. If you ever decide to re-enable QAlity for the project, all of the test cases that were created in the past will be there.
