When you say server settings, I'm suspecting you mean policies, like on access scan, etc... ?
If so, you could export policies (or share them) from the parent epo server, import them in to your epo, assign them accordingly and be done.
You potentially need to check and marry the two policies, so if they have some file exclusions that you don't have, and vice versa, then you have to add your exclusions in to their set. It comes out to be a very tedious job, but at least it's possible. I hope that is what you were asking.
