Hello,

First of all, as @scott28tt said, your ESXI hosts need to be joined to vCenter.

The host profiles allows you to clone the configuration form a host to other hosts, it includes the following settings :

I think the section that matter for you the most are network and security.

First, you need to extract the host profile from the source ESXI, then configure the necessary parameters in the extracted host profile, after that you attache it to the new ESXI.

You can check on youtube, there are many tutorials on how to use host profiles.
