We are migrating to a new website & domain name. Current and new website have two different are located on two different machines. If DNS entries are changed to point old domain name to new server, do I even need to change the host header values on old IIS server? In a couple of days after the switch over we are planing to stop old IIS site from running.

No, but you need to configure the new machine properly.
The host header does not describe the machine, it describes the domain that should be shown.
