How Virtual Machine and System Image Settings Are Affected
The VMware virtual machine created by the importer contains an exact copy of the disk state from your source virtual machine or system image, with the exception of some hardware-dependent drivers and, sometimes, the mapped drive letters.
Settings from the source computer that remain identical include:
Since the target and the source virtual machines or system images have the same identities (name, SID, and so on), running both on the same network can result in conflicts. If you are planning to redeploy the source virtual machine or system image, be aware of this issue and do not run both the source and target images or virtual machines on the same network at the same time.
You can resolve the duplicate ID problem by using additional tools, such as the Windows 2000 System Preparation Tool (Sysprep). For example, if you use Virtual Machine Importer to test the viability of running a Virtual PC virtual machine as a VMware virtual machine without first decommissioning the original Virtual PC machine, you need to resolve the duplicate ID problem.
