Exchange 2013 / 2007
Would there be any disruption in the ActiveSync and OWA services? if I deploy new exchange 2013 server in a VM with Windows 2012 and just keep it active for a week before actual migration or before applying any certificate services or before changing any routing and DNS.
Our emails comes from inbound securence filter. I hope if the public and private IP forwarding does not know about new Exchange the old exchange should continue to work, but I skeptic after seeing article about Exchange 2013 SSL automatically trying to proxy services after it was introduce to existing environment

I am planning to change external and internal DNS only after introducing new certificate and after adding _autodiscover SRV record to resolve unregistered name. Once I know, it works fine with test user and internal DNS then I will add record to external DNS for_autodiscover SRV, and add forwarding on firewall.
