We are trying to migrate to new Exchange 2013 CAS servers, however the autodiscover xml information they handing out still has the old server name in it
X-CalculatedBETarget: old server
X-DiagInfo: old server
X-BEServer: old server
Persistent-Auth: old server
X-FEServer: old server
When we stop the services on the old server as a test Autodiscover fails even though dns etc points to the new server, we are not seeing any other issues, owa etc all works.
If I look at CN=autodiscover in ADSI there is no mention of the old server.
We are migrating from a single server to a loadbalanced pair, what entry should we use to ensure autodiscover doesn't fail in the even one server is down?
