LPS-35778 Upgrade to 6.2 M6 failed on DB2 because of VerifyUUID

Hey Alberto,

Could you please test the scenario with my changes?

Before you proceed, please increase the verbosity of the verify subsystem (in portal-log4j-ext.xml), should it fail in your environment, I'll be able to fix it easier.
