Siebel Database Upgrade Guide > Performing the Siebel Incremental Repository Merge > Process of Meeting the Requirements for an Incremental Upgrade to Siebel CRM Version 15.5 or Later, Using the Incremental Repository Merge >

Before You Begin

Refer to and follow the tasks listed in Preparing for Siebel Database Upgrade.

You must have the Siebel Enterprise Server, which includes the Siebel Gateway Name Server, the Siebel Server, and the Siebel Database Server, installed. You must have installed Siebel Innovation Pack 2015, Patchset 5 or later (version 15.5 or later). For installation information, see Siebel Installation Guide for the operating system you are using and other applicable documentation.

NOTE:  Prior to running incremental repository merge, you must have one and only one repository in your development instance and that repository must be named Siebel Repository. Also, if you must delete any additional repositories, the only acceptable way to do so is to select the repository record in Siebel Tools and delete it. It is not acceptable to delete repositories using direct SQL.

About the Siebel Server and Siebel Tools on Windows

It is recommended that the Siebel Server and Siebel Tools be installed on the same Microsoft Windows computer. If your Siebel Server is installed on Windows, then the merge process automatically starts Siebel Tools to execute the incremental repository merge. For this reason, the Siebel Database Configuration Wizard must be started from the computer where Siebel Tools is installed.

If the Siebel Server is not installed on the same computer as Siebel Tools, then map a network drive from the computer where Siebel Tools is installed to the computer where Siebel Server is installed. Use this mapped drive to specify the location of the Siebel Server when you run the Siebel Database Configuration Wizard.

NOTE:  Because the merge process requires extensive database resources, it is recommended that, before beginning the incremental repository merge process, you set the general cursor size to 5000.
