Issue

When running an upgrade on the FIM Service and Portal the upgrade rolls back without warning or error. 

A verbose log of the installed captures more details:

Cause

 Unknown.  Issues seems to come up with upgrade from 4.0.2592

Solution

 Prior to attempting the upgrade again, run a change-install on the FIM Service.  Be sure to generate a new certificate during the install.  Once the change-install is completed, perform the upgrade on the FIM Service and Portal.
