Classic and hierarchical zones
If you plan to deploy using zones—which is the most common deployment model—you have to option to create classic or hierarchical zones. Classic zones provide a simple model for organizing computers and backwards compatibility for organizations with older versions of the Centrify agent. Hierarchical zones enable you to establish parent-child zone relationships, allowing profile attributes, rights, and roles to be inherited down the zone hierarchy. Classic zones are peers to each other and do not inherit profile attributes, rights, or roles from each other.
One of the first decisions you need to make in planning your zone structure is whether you will use classic zones, hierarchical zones, or some combination of both.
