To add to Todd's comment, a site is no longer a security boundary in a multi-level CM12 hierarchy and things like collections become "global data".
Here's some good info (including what is and what is not) on global data: http://blogs.technet.com/b/server-cloud/archive/2012/03/06/data-replication-in-system-center-2012-configuration-manager.aspx CM12 does support overlapping boundaries for content location<http://technet.microsoft.com/en-us/library/gg712679.aspx#BKMK_BoundaryOverlap>, but I think when it comes to overlap and site assignment, you'd end up with some undesired results From: [email protected] [mailto:[email protected]] On Behalf Of Todd Hemsell Sent: Wednesday, May 22, 2013 4:08 PM To: [email protected] Subject: Re: [mssms] RE: Overlapping Boundries everything you make on one site goes over to the other site and vice versa. They are all going to be members of the same "Site" no matter what once they are joined to a CAS. All the same site code. At least that is my understanding. What you are doing is not going to accomplish any discernible goal unless you have 500 thousand machines or something.

I believe that we could potentially use a RBA system however it was decided not to go that way for the sake of scaling the system in place. However I am still having trouble finding a good resource for having two Primary Sites Boundaries that could potentially overlap either accidentally or by design. Has anyone tried this?

Did you have a technical reason to place two sites (size, geo-location, etc.)? Could you get by with RBA?

We have two SCCM primary sites that are both connected to a CAS server. Both primary sites are for different business units and but all of the IP addresses of the machines that they are to manage are intermingled quite badly. As such I cannot use sites or subnets to create a boundary. And most of the time to use a range it will have to be a range of one IP. So my question is can we overlap the boundaries for the two primary sites. Then use group policy to push the SCCM client onto the machines, having the group policies, which will be linked to two different non-overlapping OU's, decide which primary site the computer will be a member of? We would not be doing any automated client deployment from the SCCM servers themselves. Can this be done or is there something that I am missing?
