Hello,
My company wants to upgrade from SBS/Exchange to 2008 R2 and Exchange 2010 to replace our SBS boxes. I have seen a number of articles that address this, but none that involve my situation involving two SBS boxes. Our main office has two SBS 2003 R2 boxes, one that has Exchange loaded (mail.company.local), and one that acts as a file server (city.company.local).
I've read that I can join one the 2008 R2/Exchange 2010 to the mail.company.local domain and migrate, but that is a separate forest, and I want the main forest to be city.company.local and eliminate the mail.company.local domain or at least have it in the same forest.
My question is can I join a 2008 R2/Exchange 2010 box to the city.company.local domain and migrate the mail.company.local Exchange to that domain without the ability to establish a trust between the new server in city.company.local and the old SBS box? If not, how should I go about doing this migration and keep city.company.local as the forest? Thanks in advance!
