When attempting to apply an imported policy to a Symantec Endpoint Security (SES) device group, you encounter the following warning which prohibits the action:
Release : 14.3 RU1
The policy was imported from the Symantec Endpoint Protection Manager (SEPM). SEPM policies that have been imported into the Integrated Cyber Defense Manager (ICDm) can only be applied to the 'My Company' groups that will be present after a SEPM has been enrolled in the ICDm. Only native SES policies can be applied to the SES Device Groups Hierarchy (Default Group).
When applying policies to the Default cloud groups, only apply policies that were created in the ICDm. Imported SEPM polices will fail to apply to Default group hierarchy.
