Hello all. I have been asked to upgrade a medium-sized company (7 locations, 9 DC's, few hundred users) from 2003 Server to 2003 R2. I have yet to perform an actual upgrade to R2 (just new installations), and before I touch this environment, I'm just look for some suggestions or perhaps anyone with prior experience can offer their opinions on how smooth this upgrade went. Are there any prerequisites to performing this upgrade? Does the existing Schema have to be extended?
Thanks in advance for any help.
