    Running ADPREP to update the AD schema, and raising the domain
    functional level, are not the same right?

    It seems you have to update the AD schema to add a DC of a later OS than
    that which exists on the domain.

    Raising the domain functional level is independent of adds/upgrades of
    DCs and raises the AD functionality throughout the domain.

    So you can have a mixed domain of say, Windows 2K3, 2K8, and 2K8 R2 DCs,
    in this example it must have an AD schema of 2008 R2. However, the
    domain functional level matches the oldest OS (or earlier if desired);
    in this case the domain functional level can be no higher than 2K3.

    To raise the domain to domain functional level of 2008 or 2008 R2, there
    can be no DCs with an OS older than the desired domain functional level,
    so older DCs would need to be taken out of service as DCs.
