About Installation Tasks for Siebel CRM

Use the Siebel CRM installer to download and install Siebel CRM server and client modules, including Siebel Gateway, Siebel Server, Siebel Application Interface, Siebel Web Client, Siebel Tools, and other modules. This chapter describes new installations, update installations, and migration installations.

Before installing Siebel CRM modules, review the following and perform any necessary preinstallation tasks:

After a new installation, you install the Siebel database and then you configure Siebel CRM modules using the Siebel Management Console. After a migration installation, you run Incremental Repository Merge (IRM) on the Siebel database.

Use the instructions in this chapter to install the following Siebel CRM modules:

Siebel Enterprise Components (includes Siebel Application Interface, Siebel Server, Siebel Gateway, and other modules)
New Database Repository (requires installing Siebel Enterprise Components)
Ancestor Database Repository (requires installing Siebel Enterprise Components)
Siebel Web Client
Siebel Tools

You can install and deploy multiple instances of Siebel CRM modules. For example:

You can optionally install Siebel Gateway on multiple nodes in order to support Siebel Gateway clustering. For more information, see Configuring the Siebel Gateway Cluster.
You can optionally install Siebel Server on multiple nodes in order to support Siebel Server load balancing. For more information, see About Installing Additional Siebel Servers for an Existing Siebel Enterprise.
You can optionally install Siebel Application Interface on multiple nodes in order to configure load balancing for these Siebel Application Interface instances. For more information, see Planning the Siebel Application Interface Topology.

You perform migration installations using the same installer that you use for new installations. A migration installation replaces your existing installation with a new installation. The installation location, installation languages, server configuration data, and other settings from the existing installation are used for the new installation, where feasible. Before the new installation is performed, the existing installation is moved to a backup location and can no longer be used.

Caution: Before you install Siebel Application Interface as a migration installation, you must remove the existing configuration for the Siebel Web Server Extension (SWSE) from Siebel CRM 16.x or earlier. If you are using data encryption, then you must back up the key file. For more information, see Additional Tasks for Migration Installations.

Note: After completing all of the migration installations, you must configure the Siebel Application Interface. A migration installation of Siebel Application Interface does not copy customer configurations or files from your existing installation of SWSE to the new installation.
