Data Loss Prevention 14.5 : Import Policy
You are now able to import policy into a DLP enforce even if they were created with an other one. All related object (a part EDM/IDM which must be created on their own) will be imported. You can only import policy one by one (if you have performed a global export you have to extract xml file before performing import).
You will be notified of impact on your existing object, expecially if you already have a policy with same name (policy name is used as key to detect if it already exist).
As seen in the video, if it already exist, policy rules will be overwritten or deleted if not present in imported policy.
