We are thnking about repalcing our core DC's/GC's in our HUb. Our AD design
is a hub and spoke topology where the spokes are all 2003 GC's. We are also
using Exchange 2003 with the thought to upgrade to 2007 but first we would
like to get our core DC's/GC's up to 2008. Can Server 2008 GC's/DC's coexist
with 2003 gc's i this tolopology? Please advise...

Hello jskalicky,

Should work without any problem:

But also saw a posting about problems to create mailboxes when 2008 dc/gc
is in the domain with 2003 exchange. See posting "Still need help with mailboxes...."
from 05.05.08.20:02 and also "Creation of mailboxes after migration" from
01.05.08 23:52

Best regards
