script powercli to Assign tag in a category to vms and update

Hi,

I have a script to assign a tag in a category to vms from a csv

it works well  with powercli 6.5

but I have to replace the tag when the tag exists

or a powercli script to erase the tag with the category Application_Patch

the powercli scrip is :

Connect-viserver vcenter1 -user vcenteruser -pass vcenterpassword

$pathDev ="C:\Scripts\Tags_patch\ressources\"

set-location $pathDev

$CMDBInfo = Import-CSV C:\Scripts\Tags_patch\ressources\cmdbinfo.csv

ForEach ($item in $CMDBInfo)

{

$Name = $item.Name

$Tag = $item.Application_Patch

#Write-host "Nom SRV : " $name " Categorie"  $tag

Write-Host ".... Assigning $Tag in Category Application_Patch to $Name "

Get-VM $Name | New-TagAssignment -Tag $Tag

the csv file is like this :

"Name","Application_Patch"

"srv1","5_Autres"

"srv2","4_Nuit"

Thank you for your help
