I'm having trouble finding much information on whether or not it is possible to install multiple SCCM 2012 hierarchies in the same Active Directory forest. We have a 2 domain forest: the root domain and one child domain. Each domain has a different set of IT admins that report up different sides of the company org chart, each IT group does their own thing other than the rare occasions that Enterprise Admins or Schema Admins need to get involved. We have a SCCM 2012 sp1 CU3 hierarchy installed into the root domain. The IT group that manages the child domain is showing interest in wanting to set up their own SCCM 2012 hierarchy in the child domain. Is this possible? Any links to documentation on how to set this up, special considerations for this approach, any configurations that are different than the normal SCCM install, etc... would be appreciated. If it's not possible, I know we can use a CAS and just give them their own Primary site, but for the purpose of this question, I'm just interested in whether 2 hierarchies can co-exist(supported config) in the same forest, and whether there are any special considerations around setting this up.
Thanks in advance.
