Currently have our Primary Domain Controller on a Physical Dell PE2650, it is also our Primary DNS, DHCP, Active Directory and File Server on Server 2003. Looking to do clean install on VM to upgrade PDC to Server 2008 R2, keep as DNS, DHCP, AD only. Then demote the physical domain controller, format and do new install of Server 2008 and only have it has backup domain controller. Also would be creating new File server on 2nd new VM on Server 2008 R2.
Our secondary DC at the site is also an Exchange Server 2003/DNS server. We are planning on getting a new Dell PowerEdge Server and only having it as a stand alone, no domain controller. Perhaps create a 3rd VM just as a DNS server.
Are the steps above appropriate to take? What should I look out for? I'm concerned about the migration from 2003 to 2008 from a physical to virtual environment.
