We are transitioning from 2003 to 2010. Right now I have 2003/2010 at Site "North" and 2010 at site "South". The 2010 servers from both sites are in a DAG. The setup for 2010 in Site North is 2 CA/HT servers and 3 mbx servers. The setup at Site South, is 1 CAS/HUB/MBX.

We want to test out a LB solution that we have for MAPI traffic. Right now we are only LB'ing the web-based traffic. We do not want to interrupt MAPI traffic at Site North, and only test accounts and a passive DAG copy exist at Site South, so we were thinking of creating an A-Record for southArray.domain.com and applying this to the South AD site, and then only updating the RpcClientAccessServer database property on the test DB's in Site South.

I just wanted to make sure I was not missing anything and if you guys think this testing plan is solid and should not interrupt any MAPI traffic at Site North?

Doing the DNS change will work fine. Make sure you lower the TTL on those DNS records to like 5 minutes in advance. Active Directory, 4th Edition - www.briandesmond.com/ad4/ Okay thanks for the tipShon
