I have Exchange 2003 SBS. I want to move just the Exchange functionality to our new server which will have Server 2008 R2 x64 with Exchange 2010 x64.
What would I have to do in order to keep SBS like it is and setup the new server to just take care of email?
I found this guide http://milindn.files.wordpress.com/2010/01/rapid-transition-guide-from-exchange-2003-to-exchange-2010.pdf
and was wondering if it is applicable because I have SBS.
What is the safest method that will allow instant rollback if anything goes wrong?
