Preparing to Start the Siebel Upgrade Wizard

This task is a step in Process of Performing an Incremental Upgrade of the Siebel Database from Siebel CRM Version 8.1.1.x and 8.2.2.x (SIA Repository) and Version 15.0. Use this task to run the Siebel Upgrade Wizard.

Environments: Development, production test, and production.

When you run the Database Configuration Utilities on Windows, there is a prompt asking whether you want to start the Siebel Upgrade Wizard. When you run the Database Configuration Utilities on UNIX, you must start the Siebel Upgrade Wizard manually.

The Siebel Upgrade Wizard executes the upgrade of the Siebel database. The Siebel Upgrade Wizard takes a master configuration file as input. This file contains environment information and a driver file name. The Siebel Upgrade Wizard executes the steps in the driver file to perform the upgrade.

Because the Siebel Upgrade Wizard performs the steps in the driver file, it lists the steps in a state log. The state log is located in the following directory:

siebsrvr/LOG/process/state

In the directory, process refers to the upgrade process. For example, upgrep_dev_811sia indicates that the upgrade is from 8.1.1, and that the upgrep process is being run in the production test or production environment.
