About importing and exporting policies

Symantec EDR
imports duplicate policies gracefully (i.e.,
Symantec EDR
identifies when an entry is a duplicate and makes no changes to the original entry).
When you export policies, the exported file is in .json format.
Symantec EDR
finishes importing or exporting policies, it provides a success or failure message. The status also provides the number of duplicate policies, if any are found.
A message appears if process times-out.
You can also import policies using a Python script, and import and export polices through the API.
