When you tried to migrate your existing Workstation/Player VM to VMware Server, the moment when you tried to add it to the Inventory, you were prompted with an error: "The server could not complete a request (HTTP 12029)". Well this happened in my case where my VM Guest OS is running Windows Server 2008 R2 64-bit. The reason why I switched to VMware Server is mainly because it's FREEEEE...
What you should do now is to get a copy of VMware Converter (also FREE) from VMware's website. Previously it was only known to me as a tool to convert a physical machine into a VM image. But in fact it could be used to convert between varied versions of VMware products too! Just grab its installer and install it on your computer and do the conversion. It works!
