I'm going to update ESXi 5.5 hosts in my cluster but I don't know Update Manager component, so I ask if it's possibile to patch single host so that I can test VM on it and afterwards to extend update to the other hosts.
Do you suggest to apply all updates or it's usually to give priority to security updates? I'm using Vmware image of HP beacuse my hosts are blade Proliant servers.
How can I start? Do you have to suggest quick start guide?
