The requirements for the physical source computer depend on whether you are performing an online or offline P2V conversion. In either case, VMM temporarily installs an agent on the physical source computer that you want to convert. With online P2V, VMM uses Volume Shadow Copy Service to copy data while the server continues to service user requests. The source computer is not restarted during the conversion. With offline P2V, the source computer restarts into the Windows Preinstallation Environment (Windows PE) before VMM converts the physical disks to Virtual Hard Disks (VHDs).

To perform an offline P2V conversion, your source computer:

Supported Operating Systems

To perform a P2V conversion, your source computer should contain one of the following supported operating systems:

  • Windows Server 2008 (32-bit)

  • Windows Server 2008 (64-bit)

  • Windows Server 2003 (32-bit) SP1 or later

  • Windows Server 2003 (64-bit) SP1 or later

  • Windows 2000 Server SP4 or later (Offline P2V only)

  • Windows 2000 Advanced Server SP4 or later (Offline P2V only)

  • Windows XP Professional (32-bit) SP2 or later

  • Windows XP Professional (64-bit) SP2 or later

  • Windows Vista Service Pack 1 (32-bit)

  • Windows Vista SP1 or later (64-bit)

VMM does not support P2V on source computers running Windows NT Server 4.0. However, you can use the Microsoft Virtual Server 2005 Migration Toolkit (VSMT) or third-party solutions for converting computers running Windows NT Server 4.0.
