I am planning to demote a child domain - which consists of two DCs - DC1 and DC2. I've been reading up on how to go about this and I'm a little confused on a couple of things. First - which order should I demote the DCs? DC1 is the RID, PDC, and GC. DC2 is the Infrastructure Master. Should I transfer ALL roles to DC1 before running DCPROMO? Or do I just run DCPROMO on the IM first and then run DCPROMO on the last server which is RID, PDC, and GC? Also, I've read conflicting accounts of who I should be logged in as while demoting the child domain. Should I be logged in as domain admin for the child or the parent (root)?
