Root Cause

A defect or configuration issue in the operating environment. From the log files see that you are using the db2jcc.jar which is a JDBC 3.0 compatible driver.  Per the platform support guide you need to be using db2jcc4.jar which is a JDBC 4.0 compatible driver.  

Resolution

Make the following change to the operating environment: 

In the setupDatabase.properties file update the pega.jdbc.driver.jar property to use the db2jcc4.jar JDBC driver jar and resume the upgrade.
