Designing a zone structure for your environment
Because the flexibility of hierarchical zones is a key element in designing the zone structure for your deployment, the next sections describe how to set up and use parent and child zones through sample deployment scenarios. The scenarios illustrate a basic deployment model, which will then be used to discuss how to migrate existing users and groups to Active Directory.
Your own zone structure and deployment model can be more complex than the one described in this guide. However, the deployment model described in the next sections is intended to ensure that you have a successful initial deployment. Over time, it is likely that you will change and adapt the zone structure to requirements that are specific to your organization. There are also multiple ways to accomplish the tasks described in the next sections of this guide. You can use other strategies and techniques for deployment if appropriate for your organization.
