Yes, the documentation states that the Update Manager PowerCLI 6.0 is only intended to be run against VUM 6.0. Has anyone tried running it against a VUM 5.5 server though? Any really broken behavior?
The reason I ask is that I would like to upgrade my PowerCLI environment to the newly released version, but then I found that the 5.5 version of the Update Manager PowerCLI wouldn't install.
