We need the R2 functionality of the Interoperatability for unix. I have already done the Schema update to R2. Forest domain level is 2003 interim My question is this. Can I upgrade only 1 DC to R2? Does it have to be the PDCe or can it be one of the others? Thank you Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
