Migration of virtual machines with snapshots is possible if the virtual machine resides on shared storage accessible to source and destination hosts.

Migrating a virtual machine with snapshots is permitted, regardless of the virtual machine power state, as long as the virtual machine is being migrated to a new host without moving its configuration file or disks. (The virtual machine must reside on shared storage accessible to both hosts.)

If the migration involves moving the configuration file or virtual disks, the following additional restrictions apply:

The starting and destination hosts must be running ESX 3.5 or ESXi 3.5 or later.

All of the virtual machine files and disks must reside in a single directory, and the migrate operation must move all the virtual machine files and disks to a single destination directory.

Reverting to a snapshot after migration with vMotion might cause the virtual machine to fail, because the migration wizard cannot verify the compatibility of the virtual machine state in the snapshot with the destination host. Failure occurs only if the configuration in the snapshot uses devices or virtual disks that are not accessible on the current host, or if the snapshot contains an active virtual machine state that was running on hardware that is incompatible with the current host CPU.
