I'm running vCenter 4.0, and in the middle of doing an upgrade to 5.1 (using the separate installation method). So far Single SignOn, WebClient, and Inventory Services were installed fine.
While updating the actual vCenter Server, I got this error: "The SSL certificate for this product is expired. See Knowledge Base article kb.vmware.com/kb/1009092."
So reading that KB then pointed out "If you are upgrading to vCenter Server 5.1, see Implementing CA signed SSL certificates with vSphere 5.1 (2034833)."
Reading that KB, all I can say is wow! Is this really all necessary? I'm wondering if maybe I just need to upgrade the host certificates? Or some way to tell it to ignore expired certs?
