2 Change Auditor Installs, how to move to 1

I am looking for some direction on how to collapse 2 change auditor installations into 1.  Both are running the same version, 7.0.3 (for now) but are in 2 separate forests.    I'd like to point our agents and coordinators in Forest A to the installation in Forest B making that our new primary Change Auditor.  Can i build new coordiantors in forest A that point to the sql/Change Auditor in forest B then change the agents to use the new coordinators?
