I have just spent time trying to upgrade an existing VCSA from 6.0 to 6.5.
The two stage process appeared to complete without any errors and indeed reported a successful completion.
However: When connecting to the new VCSA through a web browser and logging in, a series of error prompts were presented, all claiming an internal error with error #1065 occurred and giving different call chains.
Before I go to the lengths of copying out the call chains (no direct electronic access the system in question) and bringing it to my desk for research, is this indicative of something fundamental I may have overlooked?
For information: Dismissing the alerts (i.e. clicking NO to reloading the web client) I eventually get to the main window and able to browse around the clusters, hosts and VMs. It all appears to be present and correct. I haven't however been able to find any actions that work. I can't open a console on a VM, it silently fails. Likewise trying to edit a VMs settings. Trying to power up or shutdown a VM doesn't work either.
what version of vCenter 6 where you running?
Upgrade of vCenter 6u3 to 6.5 is not supported...
VMware vCenter Server 6.0 Update 3 Release Notes
I would suggest re-install of Client Integration plugin. see if that helps.
Dan_Johnson : The old VCSA was 6.0U2. Why would 6.0U3 release notes tell me why an upgrade of 6U3 t0 6.5 is not possible?
npadmani : That is a possibility. I recently decided to try patching the existing installation instead and this at least complained about the Client Integration plugin and prompted me to upgrade it, which I did.
