I have inherited a problem and I’m not sure where to start. A client tried to upgrade their infrastructure. They are on vSphere 5.5 and want to upgrade to 6.5 and then to 6.7 eventually (better late than never.) They are the latest/last rev of 5.5. Hosts are on 9911214 and the vCenter is vCenter Update 3k. They also use Horizon 6.0. Prior to upgrading their vCenter to 6.5, they installed Horizon 7.12 on a new server and tried to move their terminals to the new server. They created desktop pools and moved over some of the VMs. They rekeyed the certificate for the old server to the new server as well. There are a handful of terminals that look to be working on the new Horizon server; the updated agent is installed on them and the new Horizon 7 server can communicate with them. FYI, there is only one vCenter currently, the v5.5 one. I stopped any further “updates” until we got a handle on what’s going on. Also, the Horizon 7 server is sitting on a host that isn’t managed by the vCenter. That host is supposed to be adopted by the upgraded vCenter after it updates to 6.5.
However, the remaining terminals show as “Waiting for agent communication” on the Horizon 7 admin console (they’ve been removed from the 6 admin console.) I checked the registry on the ones that aren’t communicating and the Broker entry in the registry is blank where it has the name of the new server on the ones that work.
I tried connecting to it via the desktop client and received the following message: “The Connection Server authentication failed. The tunnel server presented a certificate that didn’t match the expected certificate.”. When I disable SSL checking, I can connect and log into one of the functioning terminals normally.
I’m in the lucky position of trying to unravel this gordian knot of problems:
I’d like to make sure the current terminals can all transfer over and work with the new Horizon server and retired/remove the old one.
I’d like to make sure the certificate works correctly (should I just remove the rekeyed cert and create a new one?)
Finally, proceed with the upgrades to 6.5.
Can any of this be done?
