You may need to import a client installation package into Symantec Endpoint Protection Manager if:
You upgrade to a newer version of Symantec Endpoint Protection Manager using a database that you have restored from a previous version. The database includes older client installation packages, and you need to import the newer packages.
You should always keep the Symantec Endpoint Protection Manager version the same or later than the client version.
You can import an executable package such as .exe or .zip file packages directly, but it is not recommended. The .info file contains the information that describes the package and ensures proper migration to future builds of the Symantec Endpoint Protection client through delta updates. On the other hand, the Symantec Endpoint Protection Manager web console does not import the .info file format. In the web console, you can only import or export packages in a single file, such as in the .zip or .exe file format.
To import client installation packages into Symantec Endpoint Protection Manager
Copy the installation package that you import to a directory on the computer that runs Symantec Endpoint Protection Manager.
The client installation package consists of two files. One file is named product_name.dat, and the other file is named product_name.info. These files automatically import during the installation or upgrade of Symantec Endpoint Protection Manager. You can also get the packages from the SEPM/Packages folder of the installation file.
In the console, click Admin > Install Packages.
Under Tasks, click Add a Client Install Package.
In the Add a Client Install Package dialog box, type a name and a description for the package.
In the Select Folder dialog box, locate and select the product_name.info file for the new package you copied in step 1, and then click Select.
When the Completed successfully prompt appears, click Close.
To export the installation files and make them available for deployment, click Export this Package, and then complete this procedure.
After you successfully import the package, you can see a "Package is created" event in the System > Administrative log. The event is described with text similar to "Successfully imported the SEP 12.1 RU5 32-bit package by Symantec Endpoint Protection Manager. This package is now available for deployment."
