Clean upgrade from RHEV 3.3 to 3.4 without Reports/dwh

Issue

• I would like to upgrade from 3.3 to RHEV 3.4 without reports. How do I clean my environment from earlier reports/dwh installations?
• After upgrading RHEVM from 3.3 to 3.4 the following error is displayed excuting "rhevm-setup" command despite removing reports and dwh packages :
