Welcome to the Community - A coupld of questions
- Is this workstation the one where you have installed VMware Workstation? If it is there is a tool included that will allow you to virtualize the machine that is running the workstation software - check out page 24 of http://www.vmware.com/pdf/desktop/ws90-using.pdf
- If not, what backup software did you use to backup your workstation - there are some migrations that can read backup images.
