Symptoms

When performing an upgrade from blackpearl 4.5 with 1420 > 4.6.7, the install fails on upgrading the databases.
 

Diagnoses

When performing an upgrade from blackpearl 4.5 with 1420 ? 4.6.7, there was a schema check that failed. This caused the setup manager to run the script that creates the identity.identity table, but because it exists already, the installer fails.
 

Resolution

As a workaround, e removed the line that executes the script that creates the identity.identity table from a config file. After removing the line, the upgrade went through as expected.
