Active Directory upgrade from Win 2008 to Win 2008 R2
Posted on 2011-11-01
Hi, we have a Win 2008 (NOT R2) forest root with four Win 2003 R2 child domains under it.
We want to introduce a Win 2008 R2 domain controller into one of the child domains so we will need to update the schema with Adprep /forest and adprep /domain commands.
If I understand correctly, this will update the AD schema on the forest and all child domains.
However, I am wondering what testing we would need to do? We have Exchange, domino, ISA, IIS and other applications in our environment and obviously updating the AD schema will affect the underlying domain security for all of these.
Should we be performing an extensive test of everything, or am I being overly cautious??
