If you have VirtualCenter, you can shut down the VM and cold migrate it. If not you can shutdown the VM, un-register it. copy the vmdk file using vmkfstools -i then either create a new VM and tell it to use an existing drive or copy the other VM files with SCP and re-register the VM with the ESX host.
You can also use the VIC to do this. Select Migrate then when it comes time to select the host, select the same host, and then check where it says to use a different VMFS. Select the alternative VMFS and finish the wizard.
