I am planning to do my first IPCC enterprise (7.5.1) installation. I have experience with IPCC express. Now I am going through the tons of documentation and find it little bit confusing since there are bunch of now components which I don't know yet what they do. If somebody has some experience with what is the minimum configuration for the IPCC enterprise. Basicly I want to try out the integration with Siebel CAD but keep the installation as small and simple as possible.I see it is also possible to virtualize the servers, but from 7.5.3. Am I right? Any advice is welcomed.
