Single forest, and domain at small company of about 100 users. Single Exchange 2003 server. All prep work for a 2010 Exchange server has been done. Should receive new hardware next week to use as a new single Exchange 2010 server.
My current mx record points to a public ip address which is mail.mycompany.com/exchange.
This public IP is NAT'd on my firewall to the Exchange 2003 servers internal IP address.
The Exchange 2003 server is using a VeriSign SSL certificate for mail.mycompany.com/exchange.
So when I install Exchange 2010 and come to the configuration of setting up OWA and Activesync, is it as simple as bringing in a NEW UCC certificate and then changing the NAT entry on the firewall to point to new Exchange 2010 servers IP address? If so, what entries do I need to put on the server?
- the current entry (mail.mycompany.com/exchange), which will be used by the NEW server(?)
- an old one for the Exchange 2003 server (legacy.mycompany.com/exchange)(?)
- an entry for the internal NETBios names of each of the Exchange servers???
Thanks for any help. This is the only part I'm really worried about....Keeping OWA and ActiveSync flowing in coexistence while the transition takes place...
