In Site A we have one CAS server that is internet facing
both internal and external urls are mail.exchange.com
now i have to take this server down and i want to point all the connections to another CAS server in site B.
The CAS server in Site B is not internet facing, internal url for this CAS is servername.exchange.com, no external url is present.
here are my questions.
1. how make the CAS server in Site B as internet facing.
2. how to change DNS records so that all connections will point to SiteB CAS server.
3. Do i need change only internal DNS records or External DNS records.
