Hi, we are moving exchange 2007 from one server to another. In reality, it's sbs 2008 but don't think it's relevant. For now, both exchange 2007 are co-habiting, did not move anyone yet.
My question is regarding the public certificate and what to do for internal access. In the internal dns, I created zone that points remote.externaldomain.com and autodiscover.internaldomain.com to the old 2007. Externally, it points to my public IP and redirect https to the old. Since there will be a transition, what should I do regarding the certificate. At one point (phase 1), I will move everyone that do not use cell phones to connect to exchange, do not use owa, only internal outlook.
Second phase, I will move the rest and redirect port 443 on the new server. Now after phase 1, I guess I will have outlook popups because all dns in the certificate points to the old server. Here are the choices I think I have;
- buy a new public certificate using different dns (ex; remote1 and/or autodiscover1) for the new server, and configure everything related to outlook anywhere to use remote1 or autodiscover1.
- Re-key the actual certificate and add remote1 and autodiscover1. Do not change config on old server, configure autodiscover on new server with remote1 (or autodiscover1).
Any inputs will be appreciated.
Thanks
