Script to move hosts from one cluster to another

[emcclure]

Hello,

I'm trying to write a script to migrate multiple hosts from one cluster to another.  I'm not finding much luck on the google, so I'm hoping I can get help here.  Here's the basic script (sorry I don't know how to get the code to look all pretty):

#Datacenter
Get-Datacenter | select Name | Format-Table #Lists available datacenters
$mydatacenter = Read-Host "Choose a datacenter"

Get-Datacenter $mydatacenter | Get-Cluster | select Name | Format-Table
$fromcluster = Read-Host "Select a cluster to migrate hosts from"
$tocluster = Read-Host "Select a cluster to migrate the hosts to"

#ESX Hosts to migrate
Write-Host "Select the hosts that you want to migrate"
Get-Cluster $fromcluster | Get-VMHost | where {$_.ConnectionState -eq "Maintenance"} | sort Name | Select Name,ConnectionState,PowerState | Out-GridView -OutputMode Multiple #Lists hosts that are powered on and in "Maintenance" state

#Cluster to migrate to

foreach ($vmhost in $fromcluster)
{
Move-VMHost -VMHost $vmhost -Destination $tocluster -WhatIf
}

I basically get an error stating it couldn not find a VMhost with name <cluster name>.  What am I missing?  I feel like it's something so simple, but I'm still new enough to this that I can't quite figure it out just yet.

Try like this.
You have to capture the entries you selected in the GridView ($selectedHosts).
The objects returned for waht you selected in Out-GridView, are not PowerCLI objects,

so use the Name property on the VMHost parameter on Move-VM

#Datacenter

Get-Datacenter | select Name | Format-Table #Lists available datacenters

$mydatacenter = Read-Host "Choose a datacenter"

Get-Datacenter $mydatacenter | Get-Cluster | select Name | Format-Table

$fromcluster = Read-Host "Select a cluster to migrate hosts from"

$tocluster = Read-Host "Select a cluster to migrate the hosts to"

#ESX Hosts to migrate

Write-Host "Select the hosts that you want to migrate"

$selectedHosts = Get-Cluster $fromcluster | Get-VMHost | where {$_.ConnectionState -eq "Maintenance"} | sort Name | Select Name,ConnectionState,PowerState |

    Out-GridView -OutputMode Multiple #Lists hosts that are powered on and in "Maintenance" state

#Cluster to migrate to

if($selectedHosts){

    foreach ($vmhost in $selectedHosts)

    {

        Move-VMHost -VMHost $vmhost.Name -Destination $tocluster -WhatIf

    }

}

Hi LucD,

That was it.  Works like a charm.  Thanks so much.
