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.
Enable Active Directory Delta Discovery and Delta Discovery Interval
This option applies to the following types of discovery methods:
It is a best practice to select Polling schedule when you select Enable Active Directory Delta Discovery and Delta Discovery Interval. This ensures that all the settings related to the discovery schedule and delta discovery transfer together. This is important because with Configuration Manager 2007 R3, delta discovery can change how schedules are evaluated. Unless you transfer all the settings, it is possible the resulting schedule will not be as you expect.
When delta discovery is enabled on Configuration Manager 2007 R3, as shown in the following picture, the properties used by the discovery component are set as follows:
With the configurations shown in the example, the Startup Schedule is set to the delta discovery interval of five minutes and the Full Sync Schedule is set to the polling schedule, which is daily at 12:00 am. This configuration results in the discovery method initiating a full discovery cycle at midnight every day, and running a delta discovery cycle every five minutes.
When you disable delta discovery the schedule properties for the discovery component revert to pre-R3 behavior. The Startup Schedule is set to be the polling schedule, there is no delta discovery process, and the Full Sync Schedule setting is ignored. This is shown in the following table. What this means is the discovery method will run on the defined polling schedule. Because delta discovery (incremental sync) is not enabled, there are no supplemental discovery actions.
Transferring Settings between Sites
The Transfer Site Settings Wizard needs to handle these property changes, which result in transferring different properties based on the whether delta discovery is enabled or disabled on the source and destination site. The following tables illustrate the outcome for different scenarios, which apply to both online transfers and offline transfers (exporting settings to an XML file).
When the destination site is running Configuration Manager 2007 R3, as a best practice, select the option Polling schedule when you select the Enable Active Directory Delta Discovery and Delta Discovery Interval option in the Transfer Site Settings Wizard. For all other scenarios, reference the tables above to confirm the outcome of your transferred settings.
