### Discover all VMs in a specific vSphere Cluster
$AllVMs = Get-Cluster PROD | Get-VM | ? { $_.Name -notlike 'vCLS*' }

### Create empty hash table
$hashtable = @{}

### Fill hash table with a mapping VM <> host
foreach ($i in $AllVMs) {
  $hashtable.add($i.name, $i.vmhost)
}

### Move VM to the original host
foreach ($i in $hashtable.GetEnumerator()) {
  move-vm -VM $($i.Name) -Destination $($i.Value) -RunAsync
}
