About Installing Siebel Business Applications
Each Siebel Business Applications software release from Oracle has a specific version level. The current release is Siebel Innovation Pack 2013, which refers to Siebel CRM version 188.8.131.52 or version 184.108.40.206.
You can install Siebel Enterprise Server and Siebel Web Server Extension at one of these versions, whether it is a new installation or a migration installation (patch). Other modules require that you first install Siebel CRM version 8.1.1 or version 8.2.2 as the base installation and then install the current release as a patch on top of the base installation.
The procedures in this guide are for installing all of the applicable versions of the software that are necessary to install the software at the current release level.
