You would like to know if it is possible to export policies from an installation package exported from the Symantec Endpoint Protection Manager.
It is not possible to export the policies directly from an installation package exported from the Symantec Endpoint Protection Manager.
The best way to export the policies from an installation package exported from the Symantec Endpoint Protection Manager is to install the Symantec Endpoint Protection client from the exported package.
Once the clienty is installed, you can then export the policies by opening the SEP client GUI.
Go to: Help > Troubleshooting > Policy Profile > Export
You will then end up with a Profile.xml file that contains all policies.
