How to use USMT 4 hardlinking in a Configuration Manager 2007 Task Sequence

Great post over the The Configuration Manager Support Team Blog talking about USMT 4.

Here’s a snippet:

Suppose you want to use the USMT 4 feature of hardlinking in a System Center Configuration Manager 2007 Task Sequence, but you notice that the "Capture User State"/"Capture User Files and Settings" and "Restore User State"/"Restore User Files and Settings" tasks do not have any options to perform a local capture with hardlinking.  What’s up with that?

Well what’s going on is that USMT 4, which introduced hardlinking, shipped after ConfigMgr 2007 so the hardlinking option was not available in ConfigMgr 2007. However, USMT 4 support was added in ConfigMgr 2007 SP2, and via the OSDMigrateAdditionalCaptureOptions and OSDMigrateAdditionalRestoreOptions variables, a hardlink user migration can be accomplished in a ConfigMgr 2007 SP2 Task Sequence.

Out of the box, ConfigMgr 2007 SP2 only supports USMT 4 online captures, or captures that take place while in the full Windows OS. ConfigMgr 2007 SP2 does not support USMT 4 offline captures, or captures that take place while in WinPE. Offline captures are possible using the UDI feature of MDT 2010 Update 1 when it is integrated with ConfigMgr 2007 SP2.

With that said, there are several ways that a USMT 4 hardlink migration can be accomplished in a ConfigMgr 2007 Task Sequence, including:

  1. Create a new ConfigMgr 2007 Task Sequence that supports USMT 4 hardlinking.
  2. Modify an existing ConfigMgr 2007 Task Sequence that have the "Capture User State" and "Restore User State" tasks to support USMT 4 hardlinking.

Since USMT 4 support was not added until SP2 of ConfigMgr 2007, SP2 of ConfigMgr 2007 is required for hardlinking.

USMT 4 is supported in the following refresh scenarios:

  • Windows XP –> Windows Vista
  • Windows XP –> Windows 7
  • Windows Vista –> Windows Vista
  • Windows Vista –> Windows 7
  • Windows 7 –> Windows 7

USMT 4 is not supported for Windows XP –> Windows XP scenarios.
