Error: Invalid server certificate. Use Set-powerCLIConfigurationto set the value for the InvalidCertification option prompt.
Murali SripadaCommented:
Set-PowerCLIConfiguration -InvalidCertificateAction ignore -confirm:$false

You can set them to ignore and then connect through vi-server again

Before you try the steps in production, i request you to try in a lab setup environment and test the scripts..

You can use below code to migrate multiple virtual machines at a time. You mentioned cold VMotion so I included a line to turn off the virtual machine gracefully and then migrate them to the destination. Please let me know if this helps.

$Servers = Get-Content "C:\temp\Servers.txt"
Foreach ($server in $servers)
Shutdown-VMguest $server -Confirm:$false
Write-Host -Foregroundcolorcolor Green "Virtual Machine Powered off"
Move-VM $server -Destination "Destination ESX IP or FQDN"
Write-Host -Foregroudcolorcolor Green "Virtual Machine Migrated to Destination"

I used below and was able to migrate them successfully #Put the path of the csv file
 $vms = Import-CSV "C:\test\Testback.csv"
 foreach ($vm in $vms)
 #Assign Variables
 $VMName = ($vm.Name1,$vm.Name2)
 $VMHost = ($vm.Host)
 $DD = ($vm.Datastore)
 $OldNetwork = ($vm.OldNetwork)
 $Net = ($vm.Network)
 Write-Host $VMName
 Write-Host $vm.Host
 Write-Host $vm.Datastore
 Write-Host $vm.Network
 Write-Host $vm.OldNetwork
 #Power off vms
 Get-VM -Name $VMName | Shutdown-VMGuest
 #Where the VM gets Migrated 
 Move-VM -VM $VMName -Destination $VMHost -Datastore$DD
 Get-VM $VMName | Get-NetworkAdapter | Set-NetworkAdapter -NetworkName $Net -Confirm:$false
 #Power On VMs
 #Start-VM $VMName -Confirm
