Hello My current domain name is "ABC_Dom" running AD 2003 Native and Exchange 2003. I am looking to upgrade to Exchange 2010 and my existing Domain name is not valid "ABC_Dom" ... I really don't want to change this name and I was thinking of adding an additional Domain to my existing forest like "ABC" and setup trust relationships between the two domains and install Exchange 2010 in the new domain? Any Insights ? or Suggestions
