Restrictions
The following restrictions apply to multilingual upgrades:
Installed languages must be deployed. If you have installed a language but not deployed it, then the language will not be upgraded.
A deployed language is one where you have installed the language pack, imported the user interface strings into the Siebel Repository, imported the seed data into the database, activated the seed data records added to S_LST_OF_VAL, and configured the records for MLOVs.
You cannot select which languages to upgrade. The Upgrade Wizard upgrades all deployed languages.
You cannot add or remove a language during an upgrade. If you want to add a language that is not currently deployed, then do so after the upgrade. For more information on adding new languages, see Siebel Global Deployment Guide and Siebel Installation Guide.
