Exchange 2010, New Domain, OWA and Active Sync

Last Modified: 2016-07-08
We are switching our main email to a new domain. I was wondering if I could easily coexist the new and old domains in OWA and Active sync. (I have done a little searching and I don't think it is as easy as pointing the new domain DNS entries to the server but I am coming here for a little confirmation.)

For example tell users to start using webmail.NewDom.com/owa but not have webmail.OldDom.com/owa stop working. Also have all of the new IOS devices start using mail.newdom.com for their ActiveSync but not break the hundreds of existing IOS devices that still use mail.OldDom.com.
