[Samba] Transfer GPO's between servers on different domains?

[Sebastian Arcus]

As per title, is it possible to export GPO's from one AD DC and import 
them into another, one on a different domain? Searching online, all 
posts refer to transferring GPO's between servers on the same domain, or 
restoring GPO's from backups when rebuilding a server. It is tedious to 
configure by hand 30-40 GPO's - it would save a lot of time if there was 
a way to just copy them from another working server, on another domain - 
and import them in.
