PowerCLI script to sequentially Storage vMotion VMs from a CSV File

This is a PowerCLI script that I use to Storage vMotion (s/vmotion) VMs from an input file (CSV File). This helps me evacuate VMs from a datastore that will be decommissioned and this serves like an automation. With this, I do not have to log back to vCenter and manually do storage migrations. This also have a lesser performance impact compared to simultaneously queuing storage migrations manually in case this will be done on non-peak hours.

$VMsToRelocate = Import-Csv "ListOfVMsToRelocate.csv" $Datastore = Get-Datastore -Name "datastore_name" foreach ($VM in $VMsToRelocate) { Write-Host "Relocating VM:" $VM.Name "to" $Datastore Get-VM -Name $VM.Name | Move-VM -datastore $Datastore > $null } Write-Host "Completed!"

Note that the CSV file must have a Header called Name, below is an example.

Name VM1 VM2 VM3

If you want to export the list of VMs that you want to migrate, you can use RV Tools to generate a VM Inventory, export the list to MS Excel, do your filtering there (such as filter by the storage path), and I personally like to sort them by used size (in MB), then simply copy-paste to the CSV file. You do not need to create the CSV file in Excel, I use Notepad++.
