migrate vm from vds to vss

[vmstoani]

Hello,

Need help for this script.

I have to migrate a lot of VMs from vDS to vSS.

I'm using the following script which does not work.

When starting the script vCenter logon is ok, but then the script do nothing.

No errors

$cred = Get-VICredentialStoreItem -File "D:\Scripts\Credentials\credentials.xml"

Connect-VIServer -server $cred.host -User $cred.User -Password $cred.Password

# Read Input File

$InputFile = Import-CSV "D:\Scripts\NETWORK\ARS-OFM.csv" -Delimiter ';'

# Parse the input file

ForEach ($Network in $InputFile) {

    $Clustername = $Network .CLUSTER

    $vSwitchname = $Network .VSS

    $NEWVLANname = $Network .VSSPG

    $OLDVLANname = $Network .VDSPG

    $VLAN = $Network .VLAN

# Retrieve the hosts from Cluster

$VMHosts = Get-Cluster $Clustername | Get-VMHost | sort Name | % {$_.Name}

# Loop through the hosts

ForEach ($VMHost in $VMHosts) {

    #get all VMs in this host and migrate the network to vSS

    Get-VM -Location $VMHost | Get-NetworkAdapter |

    where { $_.NetworkName -eq $OLDVLANname }

    Set-NetworkAdapter -PortGroup $NEWVLANname -RunAsync;

    }

}

Best regards

No errors, no messages in the Web Client...?

Hi Luc,

No Errors, no Messages.

I would suggest to run the script in a debugger (ISE or VSC for example), adn then check if the script actually does what you want it to do.
As an alternative you can put in some Write-Host lines at specific points in the script.

So it seems that the script stops working on this step:

$VMHost | Get-VM | Get-NetworkAdapter | where { $_.NetworkName -eq $OLDVLANname } | Set-NetworkAdapter -PortGroup $NEWVLANname -RunAsync;

But I have no idea why.

Best regards

It might be typo while copying, but there is a pipeline symbol missing at the end of the Where-clause.

$cred = Get-VICredentialStoreItem -File "D:\Scripts\Credentials\credentials.xml"

Connect-VIServer -server $cred.host -User $cred.User -Password $cred.Password

# Read Input File

$InputFile = Import-CSV "D:\Scripts\NETWORK\ARS-OFM.csv" -Delimiter ';'

# Parse the input file

ForEach ($Network in $InputFile) {

   $Clustername = $Network.CLUSTER

   $vSwitchname = $Network.VSS

   $NEWVLANname = $Network.VSSPG

   $OLDVLANname = $Network.VDSPG

   $VLAN = $Network.VLAN

   # Retrieve the hosts from Cluster

   $VMHosts = Get-Cluster $Clustername | Get-VMHost | sort Name

   # Loop through the hosts

   ForEach ($VMHost in $VMHosts) {

   #get all VMs in this host and migrate the network to vSS

   Get-VM -Location $VMHost | Get-NetworkAdapter |

   where { $_.NetworkName -eq $OLDVLANname } |

   Set-NetworkAdapter -PortGroup $NEWVLANname -RunAsync

   }

}

Hi Luc,

I've changed the script. Now it works.

# Read Input File
$InputFile = Import-CSV "D:\Scripts\NETWORK\ARS-OFM.csv" -Delimiter ';'

# Parse the input file
ForEach ($Network in $InputFile) {
    $Clustername = $Network.CLUSTER
    $vSwitchname = $Network.VSS
    $NewPortGroup = $Network.VSSPG
    $OldPortGroup = $Network.VDSPG
      

# Retrieve Cluster
Get-Cluster $Clustername | Get-VM |Get-NetworkAdapter | Where {$_.NetworkName -eq $OldPortGroup } | Set-NetworkAdapter -NetworkName $NewPortGroup -Confirm:$false
}

Thank's for your assistance

Best regards
