Access control is based on primary responsibility name. If you have defined conditional expressions for applets in the Administration-Personalization screen, plan to review these after the upgrade and verify that they use Primary Responsibility name. For more information on access control, see Siebel Security Guide. For more information on personalization management, see Siebel Personalization Administration Guide.
