As the title states, I am in the process of moving to Exchange 2013 from Exchange 2010.
This is a partially live upgrade and I want to ensure little to no downtime.
During the prerequisite check I get this message:
"Warning:
Setup will prepare the organization for Exchange 2013 by using 'Setup /PrepareAD'. No Exchange 2007 server roles have been detected in this topology. After this operation, you will not be able to install any Exchange 2007 servers."
As I stated, we do not have any 2007 Exchange servers, only a single 2010 server. This being my first 2013 Exchange install, I am not sure if this is a "point of no return" where it makes AD changes that will effect our current production network.
Any assistance would be greatly appreciated.
Thanks!
