Is there anyway to move a VM from a vmfs3 volume to an nfs volume?
If I try a cold migration on VC 2.0.2 build 61426 and ESX 3.0.2 build 63195 it errors out after about 2% complete with the error:
The virtual disk is either corrupted or not a supported format.
If I try to use vmkfstools -i to clone the disk, using either the thick or thin format, it errors out at 2% with the error:
Clone: 2% done. Failed to clone disk : Input/output error (327689)
I am able to create new VMs on the NFS mount so I know that is working.
Yes you should be able to do cold Migration from VMFS to NFS.
If these migration methods are failing, you could try VMware Converter
