"Thumbs Up" to the above post.  As an aside, the below article provides links to manual uninstall articles:

Plus, confirmation you want SEP12.1RU2 (12.1.2015.2015) or later for Windows 2012 support:

Please uninstall the current sep with the symantec removal tool (Cleanwipe) and then install Symantec Endpoint Protection 12.1.2 on the server.

Run the cleanwipe tool and uninstall the symantec client.

First supported version for Server 2012 is SEP 12.1 RU2, you can choose even SEP 12.1 RU2 or SEP 12.1 RU3

If you want to go with SEP 12.1 RU2 then you can only upgrade the Client because SEP 12.1 RU3 will be available on file connect earlier.

I would suggest to go with Competitive uninstaller utility.

As of now it's not possible with the help of SEPM console.

You can do uninstall (old package) and reinstall (new pacakge) using competitive uninstaller. This tool is not supported by Symantec

It can be found on the DVD under \Tools\NoSupport\CompetitiveUninstall.

As everyone highlighted above, Symantec Endpoint Protection 12.1.671 does not support Windows 2012 and Windows 8.

However, Symantec Endpoint Protection 12.1.RU2 and above does support Windows 2012 and Windows 8.
