I have a 2003 Server Standard primary and backup domain controller. I'm building a 2003 R2 Server on new hardware to replace the primary domain controller. One of the first steps is to run adprep/ forestprep on the 2003 std primary domain controller. Then you are supposed to run adprep/ domainprep after all the domains replicate the forestprep updates.
How do I determine if my backup domain controller has replicated and has all the forestprep updates?
Also, is necessary to run forestprep and domainprep and my 2003 std backup domain controller?
Will it be okay to have an 2K3 R2 primary domain controller and 2K3 Std backup domain controller?
