I'm having some issues that I'm hoping the community can solve. I have a vCSA 5.5 in my environment that I want to upgrade to 6.5. I downloaded the 6.5e ISO and mounted it, ran the installer. The problem is I am stuck at step 3. I input the info for the source appliance (the current vCSA 5.5) with the appropriate info which seems to take. However the info I input for the second section, the ESXi Host or vCenter Server info seems to be the issue. I have used both the direct IP for the host as well as the IP for the vCSA 5.5. Using port 5480 as I can't get further on any other port.
When inputting the info using host IP, I get the error "Failed to get an SSL thumbprint of the source server certificate for [host IP]."
When inputting the info using vCSA IP, I get the certificate warning window, which I press Yes to, but then the error is "Invalid credentials for ESXi host or vCenter Server." I have switched the username to be any of these: root / administrator@vsphere.local / vmadmin (this is our vCenter admin account) / vmadmin@vsphere.local - all come up with the same error. I know that all of these work to log in to the host directly, and that the xxx@vsphere.local accounts work when logging into the vCSA through both the web ui and using the vSphere client.
So what am I doing incorrectly, and why won't it let me upgrade? Should I just cut my losses and make a new vCSA and then remove my hosts from the old one and add them to the new one? Is there something else I should try to do?
1. Is the vCenter server running on custom certificates or default certificate ?
2. Is the certificates expired on the vCenter server ?
Not sure whether it's related, but did you install the Client Integration Plugin from the VCSA installation package prior to starting the installation?
