Can you be more specific about the error message?  This should be like any other 
case of moving linux to different hardware. If the disk drivers don't match what 
is installed you have to rebuild the initrd with correct drivers.  Or, the 
quick-fix is to boot from a live CD and copy the contents of /boot over from a 
machine (or VM) where the same version was installed on the same real or virtual 
hardware.

If you are going to VMware, you can probably use the vmware converter program 
that you can download for free.  It will convert a running machine to a vmware 
image file or from one version of vmware to another, including the ESXi server 
where you don't have normal access to the filesystem.
