Performing a database upgrade refers to migrating your Siebel custom repository and data schema from one release of Siebel CRM to a higher release. This guide describes how to upgrade the following types of installations:

  • A Siebel CRM 7.x installation to Siebel 2021.

    In this version of the guide, Release 7.x refers collectively to all versions of Siebel CRM version 7.8.2 (SIA) from which you can upgrade directly to Siebel 2021.

  • A Siebel CRM 8.0 installation to Siebel 2021.

    Note: If you are considering migrating your Siebel CRM 8.x z/OS database to Unicode format, be aware that you cannot upgrade to a later release of Siebel CRM using the standard upgrade procedure. If you migrate your Siebel z/OS database to Unicode format, you can upgrade to the latest Siebel update. However, Oracle will support Unicode database upgrades from one major release of Siebel CRM to another, or incremental Unicode upgrades, in future updates, if required.

  • A Siebel CRM 8.1.1.x installation to Siebel 2021.

    This guide does not cover the following specific upgrade paths or infrastructure changes. For help with these tasks, contact your Oracle sales representative for Oracle Advanced Customer Services to request assistance.

    • Direct upgrades to Siebel CRM version 8.1 from Siebel CRM versions earlier than 7.5.3 are not supported; you must first upgrade to Siebel CRM 7.8.2, or a later release.

    • Direct upgrades to Siebel CRM version 8.2.2.x are not supported.

    • Changing operating system type during an upgrade, for example changing from Windows to UNIX.

    • Changing database platform type during an upgrade, for example changing from Oracle 8i to IBM DB2.

    • Migrating to Unicode.

    • Migrating from Siebel Industry Solutions or Siebel Financial Services applications to Siebel Business Applications.

    • Upgrading from one base language to another. To achieve similar results, upgrade your existing base language and install the Siebel language pack for the desired language.
