PowerCLI – export import VM annotations

May 22, 2013

Quick script to export or import virtual machine annotations to/from CSV format. Very handy in situation when virtual machine was unregistered and registered back in vCenter inventory. registering VM back won’t restore virtual machine annotations.

Export

Get-VM | ForEach-Object {
$VM = $_
$VM | Get-Annotation |`
ForEach-Object {
$Report = "" | Select-Object VM,Name,Value
$Report.VM = $VM.Name
$Report.Name = $_.Name
$Report.Value = $_.Value
$Report
}
} | Export-Csv -Path D:\VMAnnotations.csv -NoTypeInformation

Import

Import-Csv -Path D:\VMAnnotations.csv | Where-Object {$_.Value} | ForEach-Object {
Get-VM $_.VM | Set-Annotation -CustomAttribute $_.Name -Value $_.Value
}
