Steps to Reproduce



Run an upgrade to 7.1.7.

Root Cause



The root cause of this problem is defect/misconfiguration in the Pega operating environment.  
The jar file that contains the class is not on the classpath during the upgrade.



Resolution



This issue is resolved through the following local-change: 

In the setupDatabase.properties file set build.conclusions=false and then run the resume script to resume the upgrade.

# Pre build the Pega Conclusions.
build.conclusions=false
