You cannot use a vSphere Client to migrate virtual machines created with VMware Workstation or VMware GSX Server into your ESX system. However, you can use the vmkfstools -I command to import the virtual disk into your ESX system and then attach this disk to a new virtual machine you create in ESX.

You must import the virtual disk first because you cannot power on disks exported in 2gbsparse format on an ESX host.


Import a Workstation or GSX Server disk into your /vmfs/volumes/myVMFS/ directory or any subdirectory.


In the vSphere Client, create a new virtual machine using the Custom configuration option.


When you configure a disk, select Use an existing virtual disk and attach the Workstation or GSX Server disk you imported.
