HI I've got a Vmware vsphere4 environment that is now running my core systems (web, mail etc) and we have been plagued over the years by a few faulty software publishes to our webserver that has then taken it out of action whilst the developers resolve the issue.
I was keen to find a way where I can take a clone of our live webserver within Vmware vsphere4, publish and test this server on the night and when we are happy swap it over with the current server. However after some searching and digging this process does not seem to be a quick, simple or even fun process.
Am i missing something or over thinking this entire process?
As so far I have this as the current process, clone the server, boot it up not connected to the Vm Network, re-configure all of the IP addresses for the box including changing the hostname. restart the vm and connect it to the network.
Publish the updated software to this server and test it.
bring down the live server for a holding page and then repeat the process in step 1 but this time putting all the ip addresses and hostnames back as they were.
Thanks for any advice
