Hi
we have exchange 2010 SP2 running on windows 2008 R2 located at two sites
SITE A (Primary)
X1 CAS,HUB
x2 MBX
SITE B (D.R)
x1 CAS,HUB
X2 MBX
The MBX server are in a DAG and both sites are connected by a 1 Gig link
when exchange was originally setup we only created a single CAS server, we now want to create a CAS Array at Both sites how can we do this without causing major disruption to our users?
1. if we introduce a CAS array do we have to include the original server in that array or can we create an array separate from the original so that we do not interrupt our existing users
2. once we introduce the CAS array will all clients start looking at that address example casarray.domain.local or will they continue to use the internal hostname CAS01.domain.local
3. will we have to deploy new outlook profile to all our users
4. do you know of any guides that you have successfully followed when implementing a CAS Array when a single CAS server is already in place
thanks in Advance
J
