If the configuration of the host from which a profile was created (the reference host) changes, you can update the local profile so that the local host configuration matches the reference host's configuration.
Once you create a host profile, you might need to make incremental updates to the profile. You can do this using two methods:
Make the configuration changes to the reference host in the vSphere Client, then update the profile from the reference host. The settings within the existing profile are updated to match those of the reference host.
Update the profile directly using the Profile Editor.
While updating the profile from the Profile Editor can be more comprehensive and provide more options, updating the profile from the reference host allows you to validate the configuration before rolling it out to other hosts that are attached to the profile.
Updating the profile from the reference host is performed from the Host Profiles main view.
