Can I copy GPOs from one domain to another domain?
In fact, the answer is YES! With the GPMC, you can most definitely accomplish this, and the steps required are, for the most part, relatively straight forward. If you have both domains in the GPMC, you can drag the GPO from one Group Policy Objects node to the other domains Group Policy Objects node and it will start to copy.
The GPanswers.com forum is closed now (thanks, spammers!)
But we encourage you to join us at LinkedIn in the “GPO Stuff” group.
Jeremy is regular there, and there is a reasonable system to prevent junk posts.
In all, we think it’s the right place to go for Group Policy-specific questions.
It’s a private group, but just JOIN it, and the owner should approve your request.
See you there !
