What’s New in the Configuration Manager 2007 R3 Transfer Site Settings Wizard
The Transfer Site Settings Wizard in Configuration Manager 2007 R3 provides two new options that are shown in the following picture: Power Management Agent and Enable Active Directory Delta Discovery and Delta Discovery Interval. To transfer these settings from one site to another, the source and destination sites must both be running Configuration Manager 2007 R3.
The Power Management Agent setting allows you to transfer the configuration of the power management agent and supports two settings; enabled or disabled.
The Enable Active Directory Delta Discovery and Delta Discovery Interval setting deserves a little more attention and is discussed below.

This option applies to the following types of discovery methods:
•Active Directory System Discovery
•Active Directory Security Group Discovery
•Active Directory System Group Discovery
•Active Directory User Discovery
