Hello! I used Microsoft Exchange Server 2003 for some time. I have 36 Active Directory Sites. When I changed to Microsoft Exchange Server 2008, I found that I must use a Client Access server and a Hub Transport in every AD site, and this means 35 more Exchange Servers than in the 2003 version. If anyone has idea of some other way of managing these sites, please let me know.
MS Exchange Server 2003 changed to MS Exchange Server 2008.
Since you are migrating from ms exchange server 2003 to the latest exchange server 2008, then I will suggest that you use the transitioning technique, but I am not so sure is if it will save you the trouble of having to use 35 more exchange servers compared to when you were using ms exchange 2003.
What you will be doing here is just adding the domain controllers of the server 2008 to the already existing 2003 directory. And after you move the flexible master operations you will just easily demote the domain controllers for the server 2003, and get them out of the domain completely.
