Database error when trying to upgrade from 8.1 to 12.1

Discussion created by larry.a.wilson on Oct 11, 2010
We are trying to upgrade our Clarity installation from 8.1 to 12.1. We are also replacing the Actuate installation with Business Objects. We have been successful with our upgrade until the point of performing the database installation task. The pre-upgrade task worked but when we tried to install the database, we got a ORA-6550 error in the PREUPGRADE_UPDATE_USER_ID_FOR_REPORTS.xml script. The problem is that the JOB_EXTENDED_TYPE_CODE column does not exist in our CMN_SCH_JOB_DEFINITIONS table. Have we missed a step in upgrading our database?
