Migrate from a Virtual Distributed Switch to a Standard Switch using PowerCLI

[bseymour]

I need to migrate vms on a host that uses a Virtual Distributed Switch to a newly created Standard Virtual Switch. I want to utilize the nics that the VDS is using for the new VSS.

The steps I want to accomplish:

1. Create a new VSS
2. Assign the VLANS that are associated with the VDS.
3. Move the nics from the VDS to the VSS.
4. Migrate the VMs to the new VSS.

I am trying to accomplish this with a script but I am not sure if this is written correctly. (See below)

Connect-VIServer vcenter -User XXX -Password XXX

# ESXi hosts to migrate from VSS->VDS

$vmhost_array = @("XXXX.com")

# Create VDS

$vds_name = "vSwitch2"

Write-Host "`nCreating new VDS" $vds_name

$vds = New-VDSwitch -Name $vds_name -Location (Get-Datacenter -Name "VDC")

# Create DVPortgroup

Write-Host "Creating new QA-LAB"

New-VDPortgroup -Name "QA-Lab" -Vds $vds | Out-Null

foreach ($vmhost in $vmhost_array) {

# Add ESXi host to VDS

Write-Host "Adding" $vmhost "to" $vds_name

$vds | Add-VDSwitchVMHost -VMHost $vmhost | Out-Null

# Migrate pNIC to VDS (vmnic11/vmnic7)

Write-Host "Adding vmnic11/vmnic7 to" $vds_name

$vmhostNetworkAdapter = Get-VMHost $vmhost | Get-VMHostNetworkAdapter -Physical -Name vmnic11

$vds | Add-VDSwitchPhysicalNetworkAdapter -VMHostNetworkAdapter $vmhostNetworkAdapter -Confirm:$false

$vmhostNetworkAdapter = Get-VMHost $vmhost | Get-VMHostNetworkAdapter -Physical -Name vmnic7

$vds | Add-VDSwitchPhysicalNetworkAdapter -VMHostNetworkAdapter $vmhostNetworkAdapter -Confirm:$false

# Migrate VMkernel interfaces to VDS

# dv QA-LAB #

$QALAB_portgroup = "dv QA-LAB"

Write-Host "Migrating" $QALAB_portgroup "to" $vds_name

$dvportgroup = Get-VDPortgroup -name $QALAB_portgroup -VDSwitch $vds

$vmpg = Get-VMHostNetworkAdapter -Name QA LAB -VMHost $vmhost

Set-VMHostNetworkAdapter -PortGroup $dvportgroup -VirtualNic $vmpg -confirm:$false | Out-Null

# Migrate remainder pNIC to VDS (vmnic7/vmnic11)

Write-Host "Adding vmnic11/vmnic7 to" $vds_name

$vmhostNetworkAdapter = Get-VMHost $vmhost | Get-VMHostNetworkAdapter -Physical -Name vmnic7

$vds | Add-VDSwitchPhysicalNetworkAdapter -VMHostNetworkAdapter $vmhostNetworkAdapter -Confirm:$false

$vmhostNetworkAdapter = Get-VMHost $vmhost | Get-VMHostNetworkAdapter -Physical -Name vmnic11

$vds | Add-VDSwitchPhysicalNetworkAdapter -VMHostNetworkAdapter $vmhostNetworkAdapter -Confirm:$false

}

Any help would be appreciated. The ultimate goal will be to perform this then disconnect the host from the vcenter 4.1 and add it to the 5.0 vcenter.
