SEP 11 Updates via SEPM 12.1

Hi All,

We are just going through our evaluation for SEP14 and we have identified 5 v11 clients running on Windows 2000 server.  Obviously we can't bring them up to 12.1 due to compatibility and we can't change the OS at the moment as this would cost a lot of money as they are manufacturing systems.  I'm aware that support for v11 has ended and definition updates haven't been available from Liveupdate for quite some time but I was under the impression that updates were still delivered via SEPM.  Can anyone tell me if this has also stopped now as I can't find anything definitive searching Google.  These clients haven't updated since December last year.

Any help would be appreciated.

Thanks
