I moved a VM from a 6.5.0 standalone ESXi host to another running 6.5.0 Update 1, like this:
- Unregistered the VM
- Used datstore browser ("Move" button at the top) to move the entire folder from the 6.5.0 host's internal datastore to an intermediate NFS datastore
- Used datastore browser on the 6.5.0 U1 host to move it from the NFS store to its own internal data store
- Registered the VM.
Now when I try to power it on, I get this (twice, once for each of its two virtual disks):
- File system specific implementation of LookupAndOpen[file] failed <--- this message is repeated 4 times for each disk
- The specified feature is not supported by this version
- Cannot open the disk '/vmfs/volumes/5a3bf07a-a95a8100-928c-0cc47ac9ab4e/A2S4_2016_EmbStd/A2S4_2016_EmbStd-000002.vmdk' or one of the snapshot disks it depends on.
- Module 'Disk' power on failed.
There are 2 sets of snapshot files, -000001 and -0000002, I assume -000002 is the youngest.
The files exist, and so do the corresponding -delta.vmdk files.
I checked if the GUID matches the store as on the new server, in case it's the original from the old server that remained stuck, but it's the right one.
I found a very similar question from some months ago. The main difference is that there it was a move from 6.0 to 6.5, but the answer there didn't really help.
