Our parent company is in Chicago and we are in Atlanta. We need to combine our Windows systems into one Forest with Atlanta as a child domain. We are currently running Windows 2003 and Windows 2008 servers in a 2003 Domain; we are also running Exchange 2003. We plan to upgrade before the migration to our corporate domain to Exchange 2007 and to 2008 Domain.
Our corporate offices are using a Windows 2003 Domain and Exchange 2003—however they are pushing out Windows 7 and Office 2010 to all of their desktops and laptops by August of this year.
I believe some of the changes on both side will cause some problems with combining the two domains with two different types of domains (2003/2008), however I am looking for the best scenario, design and project plan to make sure this migration a success and not have it turn out to be a disaster.
One other thing, we both run (for production) Linux Red Hat and we want to keep those domain separate and not have them part of this migration.
So if anyone can assist in this dilemma I would appreciate your assistance,
