PowerCLI – vMotion VM between clusters

Thanks to my college Sebastian, here his linkedin profile , I have an opportunity to post very nice PowerCLI script. Script do vMotion VM between clusters \ vDS switches and storage.

What script does:

1. Import list of the virtual machines to migrate
2. reconfigure VM to use standard switch
3. migrate VM to new cluster
4. reconfigure VM to use new vDS switch and portgroup on new cluster

[box type=”info”]

• variable $vCenter is not needed when you work only with one vCenter server
• clusters belongs to different virtual distributed switches
• storage between clusters isn’t shared

#general scope variables, customize migration targets (vhost, datastore, portgroup)if needed

$batch_input = "<path to input file>"
$vCenter = 'vc01.lab.local'
$target_vhost = Get-vmhost -name esx02.lab.local -server $vCenter
$target_datastore = get-datastore -name DS01 -server $vCenter
$target_pg = get-vdswitch -name DV01 -server $vCenter | get-vdportgroup -name 'PG-01' -server $vCenter

#load names of vms to be processed from file

$vm_names = Get-Content $batch_input

#for each name, retrieve vm object and process it

foreach ($vm_name in $vm_names) {

	$vm = get-vm -name $vm_name -server $vCenter

	#reconfigure vnic to standard vswitch to enable migration

	get-networkadapter -vm $vm -name "Network adapter 1" -server $vCenter |
	set-networkadapter -networkname 'VM Network' -connected:$false -confirm:$false|
	Out-Null

	#(s)vmotion the vm

	move-vm -vm $vm -destination $target_vhost -datastore $target_datastore -server $vCenter |
	Out-Null

	#retrieve the vm object again and connect it to target vdswitch, set-networkadapter is invoked twice
	#because it doesn't seem to allow connecting to vdswitch and changing link state to "connected" in one go (bug?)

	get-vm -name $vm_name -server $vCenter |
	get-networkadapter -name "Network adapter 1"|
	set-networkadapter -connected:$true -confirm:$false|
	set-networkadapter -portgroup $target_pg -confirm:$false|
	Out-Null

	Write-Host "$vm_name --!!!DONE!!!---"
