In my lab environment I am using the Citrix XenDesktop 7.x Connector to manage my Citrix farm. Since the release of the new System Center Configuration Manager 1511 I wanted to upgrade my environment, but I was unable to do so.
Due to a bug in the connector, the XenDesktop related collections are created with a wrong value of the CollectionType property. The Citrix Connector creates collections with the CollectionType property equals 0 (zero) instead of 2 for Device Collections. (User Collections have a CollectionType equals 1).
The Upgrade to Configuration Manager 1511 is failing due to the fact that the collections exist with the CollectionType equals zero. Let’s see how you are able to fix this in a lab environment.
