We have a root domain, and a single child domain.
I want to migrate to DFSR, but I have a few questions:
1). Will they both upgrade together, or must I do one then the other? If the latter.. does it matter which is done first?
2). Must I promote 2008 R2 DCs in ROOTDOMAIN and remove the 2003 ones prior to the DFSR migration?
ROOTDOMAIN - 2008R2 functional level
DC1 - Windows 2003
DC2 - Windows 2003
CHILDDOMAIN - 2008R2 Functional level
DC1 thru 7 - Windows 2008 R2
