Overview of UDI in MDT Deployment Scenarios

UDI supports the New Computer, Refresh Computer, and Replace Computer MDT deployment scenarios, which were described in Identifying Deployment Scenarios. UDI supports these deployments scenarios using the Configuration Manager task sequence templates provided with MDT. Table 136 lists the MDT deployment scenarios and the corresponding UDI task sequence templates used to perform the deployment scenario.

Table 136. MDT Deployment Scenarios and UDI Task Sequence Templates Used to Perform the Scenarios

Deployment scenario	UDI tasks sequences used
New Computer	Run task sequence created using User Driven Installation Task Sequence task sequence template.
Refresh Computer	Run task sequence created using User Driven Installation Task Sequence task sequence template.
Replace Computer	1. Run task sequence created using User Driven Installation Replace Task Sequence task sequence template on existing computer. 2. Run the task sequence created using the User Driven Installation Task Sequence task sequence template on the new computer.

The UDI Wizard is run by the UDI Wizard task sequence step in these task sequences at the appropriate place in the task sequence. To identify how UDI performs each of the MDT deployment scenarios, see the subsequent sections:

· UDI in the New Computer Deployment Scenario

· UDI in the Refresh Computer Deployment Scenario

· UDI in the Replace Computer Deployment Scenario

For more details about how UDI operates in each of these MDT deployment scenarios, see the corresponding sections in UDI Stage Reference in Microsoft Deployment Toolkit Reference.
