	.SYNOPSIS
    Scipt to migrate selected templates from one virtualcenter to another
 
    .DESCRIPTION
    Exports templates from a selected folder location and importes them into selected 
	cluster, datastore/datastorecluster and network of a selected virtualcenter
	
	This script requires ovftool available from vmware.com
 
    .EXAMPLE
    Copy-Templates -SourceViServer vcenter1 -DestinationViServer vcenter2 -DestinationDataStore datastore2 \
		-SourceDataCenter datacenter1 -DestinationDataCenter datacenter2 -DestinationCluster "cluster02 (Dev)" \
		-SourceNetworkName Prod -DestinationNetworkName Dev \
		-SourceFolderName templates -DestinationFolderName templates -TemplateTempFolder e:\templates\
 
     
    .PARAMETER SourceViServer
    Source virtalcenter
 
    .PARAMETER DestinationViServer
   	Destination  virtualcenter
	
	.PARAMETER DestinationDataStore
	Destination datastore or datastore cluster name
	
	.PARAMETER SourceDataCenter
	Datacenter of source virtualcenter that contaings the templates
	
	.PARAMETER DestinationDataCenter
	Datacenter of destination virtualcenter that will contain the templates
	
	.PARAMETER DestinationCluster
	Cluster in which the templates will reside
	
	.PARAMETER SourceNetworkName
	The network name of the network port group that the source template is connected to
	
	.PARAMETER DestinationNetworkName
	The network name of the network port group that the destination template will be connected to
	
	.PARAMETER SourceFolderName
	The folder the Templates reside.   This script will not recurse folders
	
	.PARAMETER DestinationFolderName
	The folder you wish the templates to be placed on the destination
	
	.PARAMETER TemplateTempFolder
	The folder to store the exported template ova's on the system that is running the script
