Plan for migration to Configuration Manager current branch
Applies to: Configuration Manager (current branch)
Before you migrate data to a Configuration Manager current branch destination hierarchy, make sure that you are familiar with sites and hierarchies in Configuration Manager. For more about sites and hierarchies, see Fundamentals of Configuration Manager.
Install a Configuration Manager current branch hierarchy to be the destination hierarchy before you migrate data from a supported source hierarchy.
After you install the destination hierarchy, set up the management features and functions that you want to use in your destination hierarchy before you start to migrate data.
Additionally, you might have to plan for overlap between the source hierarchy and your destination hierarchy. For example, you might set up the source hierarchy to use the same network locations or boundaries as your destination hierarchy, and you then install new clients to your destination hierarchy and use automatic site assignment. In this scenario, because a newly installed Configuration Manager client can select a site to join from either hierarchy, the client might incorrectly assign to your source hierarchy. Therefore, plan to assign each new client in the destination hierarchy to a specific site in that hierarchy instead of using automatic site assignment.
For more about site assignments, see Client site assignment considerations in Interoperability between different versions of Configuration Manager.
