Not sure if this is possible, but here goes :-
Our old Exchange 2003 has been running alongside our new Exchange 2010 for a while now, and all 2003 mailboxes, stores and Public Foldes are now dead.
We have :-
1 x Exchange 2003
1 x Exchange 2010 CAS
2 x Exchange 2010 MB and HUB and DAG
In order to switch over completely, we need to make sure all traffic is on 2010. Is there a utility which can monitor traffic between 2003 and 2010, thus telling us if we can kill 2003 ?
I know that 2003 will need to come out of AD etc etc once it is down, but what is the best way to check what is still using 2003 so we can redirect/move/kill.
Can we simply redirect any 2003 traffic to the DAG or CAS ?
