Dear guys,
After doing all the changes that I need to do in order to upgrade Zenoss from version 3.1.0 to 4.2.0 (Followed the steps here: http://community.zenoss.org/docs/DOC-13022 http://community.zenoss.org/docs/DOC-13022)
And after successfully resolving all the dependencies, I tried to start my Zenoss service for the very first time after the upgrade, and I'm getting the following:
WARNING:zen.migrate:Unable to index /zport/dmd/JobManager/jobs/DeviceCreationJobStatus_13e37941-071b-4ab6-80e1-e01329e02636/DeviceCreationJob_13e37941-071b-4ab6-80e1-e01329e02636

    return parent.restrictedTraverse(path[-1])
AttributeError: 'NoneType' object has no attribute 'restrictedTraverse'

I tried to fix the problem by following the solution mentioned in this discussion ( http://community.zenoss.org/thread/18690?start=15&tstart=0 http://community.zenoss.org/thread/18690?start=15&tstart=0) But I still got this same exception.

Any ideas on how I can fix this?

Thanks,
Mouhammed Soueidane

Well I managed to fix the problem, though it required me to revert back to my old installation of Zenoss core 3.2.1, and then going to the URL:
http://yourzenoss:8080/zport/dmd/JobManager/jobs/manage_main http://yourZenoss:8080/zport/dmd/JobManager/jobs/manage_main

Then I had to manually click on the "X" button of each and every job that I have once issued through Zenoss' UI. After that, the upgrade just worked great.
Note that if you go to http://yourzenoss:8080/zport/dmd/JobManager/jobs/manage_main http://yourZenoss:8080/zport/dmd/manage_main
and then go manually to the "JobManager" page, in which you have a "SELECT ALL" option and then delete, the same problem would occur since Zenoss will complain that it couldn't find a job (The job that was found to be corrupt during the failed upgrade)
