6.2.3 Considerations before deleting published Operational Content
Before deleting Operational Content, check whether there is a possibility of publishing the Operational Content again.
Once you delete Operational Content, you can no longer restore it. Therefore, if you might publish the Operational Content again, make it private, instead of deleting it.
Note that if you delete Operational Content in an environment that is used as both the editing environment and execution environment, make sure that no other users are using the Operational Content beforehand.
