Your present company has acquired a new child company that is similar to the parent company. You are tasked with adding their domain to your current forest. You know that there is more than one method that you can use to migrate or import that GPO into your existing domain. Your boss would like you to present the options available to the Change Control Board (CAB) so they can make a determination of the best course of action for this effort. They will defer to your expertise. Research and discuss the options available, including the pros and cons of each method, and the best way to test that migration before applying it to your production GPO. Keep in mind that you are presenting this to the Change Control Board (CAB) IT managers who are not experts in Group Policy Management.
