I am starting my transition to Exchange 2013 and I have a few questions.
First, I am installing my mailbox servers. The management want a phased rollout and install the CAS servers next month. Are the mailbox servers OK to run on their own until then?
Second, I have some new and old namespaces, and I want to know how I configure these.
Old names:
internal webmail : https://webmail.domain.com.owa
activesync: webmail.domain.com
internal autodiscover: autodiscover.domain.com
CAS Array name: mapi.domain.com (MXserver10 and MXserver11)
We also have a DR with:
DRactivesync: DRwebmail.domain.com
We want to use the following names in our environment. Is it still wise to have different names for our DR activesync?
We are not using a CAS Array. We will be running exchange.domain.com as a CNAME to both serverCAS01 and serverCAS02
EAS: email.domain.com
DR EAS DRemail.domain.com
Am I missing something? Please help! How do I go about setting these names so that all mail for my 2010 servers gets routed through Exchange 213, and so that there is no disruption when i set these things up.
