If your WDK-based application supports this function, you can detach an item’s lifecycle. To do so, you must have at least Write permission on the item. To attach a new lifecycle, you must have at least Relate permission on the new lifecycle.
To remove a lifecycle:
Navigate to the item.
Do one of the following, depending on the options available:
Click More>Document>Detach Lifecycle.
Check the file’s checkbox. Then select Tools>Lifecycle>Remove.
