Virtual Server 2005 Migration Toolkit (VSMT) doesn't support migrating a dynamic physical disk to a virtual hard disk (VHD). One option for dealing with this is to convert a dynamic disk to a basic disk and then perform the migration. This isn't very practical for a migration, though, because you have to remove all of the data from the dynamic disk before you can convert it back to a basic disk. For more information, see the disk management documentation for your operating system.
Alternatively, you can skip a dynamic physical disk during migration by using the /ExcludeDrives parameter of VMScript. Then, if it contains only data and no operating system, you can manually migrate the disk. Robert Larson suggests using one of the following two methods for a performing manual migration (Thanks Robert!):
If your dynamic disk contains a system partition, your options are as follows:
The option that you DO NOT have is converting the dynamic disk to a basic disk if it contains a system volume, as you can only convert dynamic disks to basic disks when there is absolutely no data, including any system files, on the disk.
