The Siebel Database Upgrade Guide does not cover the following specific upgrade paths or infrastructure changes. Contact your Oracle sales representative for Oracle Advanced Customer Services to request assistance from Oracle's Application Expert Services.

• Changing database platform type during an upgrade, for example changing from Oracle 11g to IBM DB2.
• Changing operating system type during an upgrade, for example changing from Windows to UNIX.
• Migrating to Unicode.
• Migrating from Oracle's Siebel Industry Solutions applications or Siebel Financial Services to Siebel Business Applications.
• Upgrading from one base language to another. To achieve similar results, upgrade your existing base language and install the language pack for the desired language.
