Planning Upgrades for Global Deployments

This topic describes considerations for planning a successful upgrade of Siebel Business Applications within a global deployment.

For detailed information about the upgrade process, see Siebel Database Upgrade Guide. See also Siebel Installation Guide for the operating system you are using.

Planning for the Upgrade

Addressing the questions in the following list will help you prepare for a successful upgrade of Siebel Business Applications within a global deployment.

• What database version do you use?

  Where applicable, you must upgrade your RDBMS to a supported version for the current version of Siebel Business Applications. If you are moving to Unicode, then the new database version might also make this possible.

• What version of Siebel Business Applications will you be upgrading from? Current versions of Siebel Business Applications support Unicode.
• Do you know what is involved in migrating your data to Unicode?
• Did you previously deploy a customized language not certified for Siebel Business Applications? Such languages are also referred to as unshipped languages. See also Localizing an Unshipped Language.
• Do you know how to upgrade date-time fields to Universal Time Coordinated (UTC)? See also Deploying Siebel CRM with Global Time Zone.
• Are the Siebel Language Packs that you require released and available? Are specific Siebel release levels (including patches) required for implementing these languages?
• Have you upgraded client computers (including keyboards, fonts, locales installed, and localized operating system) to support the new installed languages?
• Have you evaluated the need to upgrade all of the third-party products to versions that support Unicode, the countries or locales that you will be localizing for, and the languages that you require?

Results to Expect After Upgrading

After you have addressed the previously described issues and performed the necessary upgrade tasks, you will have gone through the following conversion processes:

1. Updating databases and Siebel versions to current versions.
2. Converting data to Unicode or to another code page that is supported with newer versions of Siebel Business Applications.

   NOTE:  Conversion to Unicode requires the assistance of Oracle's Application Expert Services. Contact your Oracle sales representative for Oracle Advanced Customer Services to request assistance from Oracle's Application Expert Services.

3. Converting selected LOVs to MLOVs.
4. Converting selected date-time data to UTC.
