We are running ZES 3.5.035 and I am getting ready to update the server and client to 3.5.144. The caveat being I am also building a new server as my existing server is on it's last legs. I know how to update the individual clients. The only issue I have is once I replace the old server with the new one by the same name the certificate is wrong as the fresh install on the new server generates a new certificate. When I upgrade the clients it keeps all the settings the same. How do I get the new self signed certificate on the client workstations after the upgrade so they will communiate with the new server? Otherwise I am going to have to remove the old client and reinstall them all by hand.
