Hey,
I just finished installing exchange 2010 on win server 2008 r2 with its active directory extending from another server(win server 2008) running exchange 2007. I want to remove the old server. They are both domain controllers and have the same domain: Exchange 2007 FQDN is mail.example.com and Exchange 2010 FQDN is mail1.example.com. Before I deploy the active directory on the new server, I performed a delegation from the old server allowing this new server to act as domain controller. But when I disconnect the Exchange server 2007 , the Exchange server 2010 stops working. Is there any other prior configuration on the old Exchange 2007 server or on the new Exchange 2010 server before I disconnect completely the old server?
Thnanks for your support
