I know it seems like a good idea but any time
I've tried P2V'ing MSCS clusters I've ended up regretting it. For file
& Print sharing there are few direct negative side effects but for
SQL clusters it is very messy. You can't P2V the virtual server name
(FS1) directly, you have to break the cluster and migrate the
individual nodes. But as I said it's a bad idea in any case.
If these are just file server clusters then the simplest thing to do
is just export the shares (they are just a registry key), build a new
clean VM, attach the existing data disk as an RDM and import the
registry keys. Once your happy that it's working, rename the machine as
the old virtual node name.
