             Summary: Upgrade to 4.2 fails in case a VMware setup has multiple zones managing the same VMware datacenter
                 Key: CLOUDSTACK-7071
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-7071
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Upgrade, VMware
    Affects Versions: 4.2.0
            Reporter: Likitha Shetty
            Assignee: Likitha Shetty
            Priority: Critical
             Fix For: 4.5.0


In a pre-upgrade setup if clusters that belong to one single VMware Datacenter are spread across 3 different CloudStack zones, upgrade to 4.2 will fail.

As part of the new mapping model for CloudStack zone and Vmware datacenter [https://issues.apache.org/jira/browse/CLOUDSTACK-1963], during CS upgrade to 4.2 we populate each of the VMware datacenter into either cloud.vmware_datacenter or cloud.legacy_zones table. But our upgrade script doesn't handle a VMware Datacenter that is managed by two different CloudStack zones and hence the it will fail with the following error -
