Hello all,
I'm trying to wrap my mind around what the difference is between a Schema Update and a Functional Level Update. For example, to have a 2012 R2 DC you need a 2012 Schema update, but not necessarily a functional level update. Is this because the 2012 R2 DC would bring in Schema objects that the current domain wouldn't have, and thus it needs to update its schema to 2012? And why can the functional level stay at a lower level with a 2012 R2 DC, say 2008 r2?
