I am soon going to dcpromo my last Windows 2003 DC to a member server, which will leave me with 2 2008R2 DCs.
The Schema is already at '47' (I think I got carried away when I installed the new DCs)
The 2008R2 DCs have the FSMO roles.
I have done a 'dcdiag' test, and it reports no failures
I have done a few 'repadmin' tests (/showconn and /shovreps), and replication seems ok.
What i plan to do is dcpromo 'away' the 2003 DC
wait for a week until that washes through
and then upgrade the domain and forest functional level to 2008 R2.
I have a few apps that i am concerned about, but i do not know how concerned i need to be...
I have a single Exchange 2007 SP2 server environment with a Blackberry professional 126.96.36.199 on a seperate server. I was able to migrate from an Exchange 2003 environment a few months ago with no real issues..
I am pretty sure that the Exchange 2007 is supported on the 2008 R2 AD, but I can't find much on the Blackberry Pro software.
is there anything else I need to be looking for?
