We have two domains in our forest domain A and domain B. Domain B contains one DC which is the operations master for the forest. Our Exchange server also resides in domain B. In domain A we have two DCs and several other servers. I would like to use ADMT to migrate the entire domain B into domain A and have all of the operations master roles be one of my servers in domain A. Are there any special considerations I should keep in mind when I try to do this?
