Hi LucD

I  have a script to move VM's from vDS to NSX-T. The script works perfect with a single Network Adapter

In my environment I have VMs with single Network Adapter and multiple Network Adapter and I would like to modify this script to cater for multiple Network adapters as well please help

Foreach ($VMdetail in $VMdetails) {

$VM = Get-VM -Name $VMdetail.VMNAME -ErrorAction SilentlyContinue

If ($VM) {
Write-Host "VM ==> $VM is a alive on the source VC ==>$global:DefaultVIServer" -ForegroundColor Yellow
}
Else {
Write-Host 'VM' $VMdetail.VMNAME' Cannot be found' -ForegroundColor Magenta
continue
}

##### Check if there is a Destination ESXi host on the specified cluster If found proceed or skip to next record

$destination = Get-cluster $vmdetail.ClusterNSXT -ErrorAction SilentlyContinue |Get-VMHost -Name $VMdetail.ESXiNSXT

if ($destination)
{
Write-Host "VM will be placed on ESXi host ==>" -ForegroundColor Yellow $destination
}
Else {
Write-host "Destination ESXi host" $vmdetail.ClusterNSXT "is not Accessible" -ForegroundColor Magenta
continue
}

##### Check if the Network Adapter for the VM is found If found proceed or skip to next record

$networkAdapter = Get-NetworkAdapter -vm $VM -ErrorAction SilentlyContinue

If ($networkAdapter)
{
Write-Host "VM Network Adaptor info ==>$networkAdapter" -ForegroundColor Yellow
}
Else
{
Write-Host "Network Adpater cannot be attahced and migration will fail" -ForegroundColor Magenta
continue
}

##### Check if the destination NSXT Portgroup is available, also check if the destination
##### networkAdapteNSXT PortGroup is found, if unavailable skip to the next record

$destinationNSXPortGroup = Get-VirtualNetwork -name $VMdetail.PortGroupNSXT |where {$_.networktype -eq "Opaque"} -ErrorAction SilentlyContinue

If ($destinationNSXPortGroup)
{
Write-Host "VM will be moved to following PortGroup ==>$destinationNSXPortGroup " -ForegroundColor Yellow
}
Else
{
Write-Host "NSX-T Overlay Switch or PortGroup cannot be found " -ForegroundColor Magenta
continue
}

#**************************** KICK OFF THE MIGRATION *****************************

# Move VM
Write-Host "NSX-T VM Onboarding in progress..........." -ForegroundColor Yellow

# Change VM Portgroup from vDS to nVDS
Write-Host "Changing Portgroup from Distributed Switch to NSX-T nVDS Segments in progress......." -ForegroundColor yellow

Move-VM -vm $VM -Destination $destination -NetworkAdapter $networkAdapter -Network $destinationNSXPortGroup -ErrorAction SilentlyContinue

}

The NetworkAdapter and the Network parameters on the Move-VM cmdlet, both accept arrays.
Just make sure the order of the network adapters and the target networks correspond.
See the remark on the Network parameter.

Hi LucD

Added an array for the portgroups it works when i have a VM with two Network Adapters and two portgroups assigned on the CSV

However if my VM has a single Network adapter it throws an error

#### Error#####

That error seems to say there is nothing in $VMdetail.PortGroupNSXT2
