I've cloned a rackspace cloud server and put it into a load balancer, whilst removing the original server. The site seems to respond fine but then I have a problem with the SSL certificate, as I'm getting an error message on https pages. The error logs say the common name is different from the server name, which I can understand.

When I do this process again, could I simply name the cloned cloud server the same as the original server or would this create problems? I'd eventually remove the original completely when everything is working fine.

Or could I name the clone server something else, but update the /etc/hosts and /etc/hostnames files to the same name as the original server? Would this be all that's required?

The domain name itself won't change.

the FQDN that your client uses to access your service has to be same as what your certificate contains. Doesn't matter what your real internal host name is.

The log error message wasn't pointing me to the real cause of the https page error. The reason I had problems with https pages was because my SSL cert was in the load balancer rather than on the cloud server so I was looking in the wrong place. Updating the load balancer was the solution.
