How Silent Installation Works
To run a silent installation, you first run an interactive installation session using the silent install syntax of the installer command. This creates a state file that the silent installation process will use. During the interactive session, your responses to the installer are captured as a set of name-value pairs in a state file. Each name-value pair represents a single prompt or field in the installation process. With the state file as input, you can then run the installer on any number hosts. This process allows you to propagate one configuration across multiple hosts in your enterprise.
The installer cannot run a state file from a different version of Communications Suite or Java ES. That is, if you create your state file using Communications Suite 5, you cannot run this state file to install Java ES 2005Q4.
