  • Windows 2k3 to Win 2k8 R2 AD migration

    Hi,

    We are planning to migrate our existing forest which is on Win 2k3 to Win2k8 R2, we currently have DNS and AD configured on our Win2k3 server. Additionally our DHCP is on Win2k8 R2, but we have a file server on win2k3 and some sql 2000 on win2k3 as well. Would appreciate if you can guide me on how to take this upgrade. We will be using the same Domain, and have two child domains in this forest as well.

    Regards,

    Assuming only one (2003) DC - other server OSes don't matter:

    Raise Domain and Forest FLs as high as possible
    Run ADPREP from 2008R2 media (32 bit option available)

    Build 2008R2 server and join to domain as member server
    DCPromo to DC (Select DNS option)
    Change DHCP to use new DC
    UnPromo 2003 DC
