I am in the process of migrating from MS Exchange to ZCS. I own mydomain.com, .net and .org, so I am currently set up and testing on mydomain.org while my users are still using Exchange on mydomain.com. The setup and testing is going great, so now I have a question.

Being very lazy, I'd love to be able to leave the mydomain.org configuration up and just add mydomain.com to it. If I add the .com domain and update the A/MX records for mydomain.com to point to the new ZCS server, will that work? I'm kind of new to ZCS, but it seems it should work just fine. Even if it will work, is it a good idea?

Thanks in advance.
