I need a solution
I'm looking to do an in-place upgrade from SEP 11.0.5 to 12.1.2 and was wondering whether this will be a straightforward process or requires a lot of preparation to ensure success? I currently have a 11.0.5 SEPM along with SQL 2005 on the same Windows 2003 server supporting about 3000 SEP 11.0.5 clients. My understanding is that a 12.1.2 SEPM should support SEP 11.x clients but can I upgrade the existing SEP11 clients to the 12.1.2. client from the 12.1.2 SEPM or do I need to utilize 3rd-party software delivery to get this done?
