Unable to import alarms from a deserialized xml object(ouput from Export-Clixml)

Hi,

I  have tried and modified the script according to my requirement given by Angel in Re: Script to export/import Alarms between VC or synchronize alarms between 2 Virtual Centers

Actually, in Angel's script for each alarm there will be a .xml file created in the folder. But, I tried script like
appending all the alarms info to a single xml file as below:

function ExportAlarm(){
    Connect-VIServer $serverToExportFrom -User 'xxxx'-Password 'xxxx'
    $alarmToExport = Get-AlarmDefinition -Entity (Get-Folder -NoRecursion) -Name
    $xml= @()
    foreach ($alarm in $alarmToExport)
    {
    $a = Get-View -Id $alarm.Id
    $xml += $a.Info
    }
    $xml | Export-Clixml -Path $fileName -Depth ( [System.Int32]::MaxValue )
}

I am able to collect all the alarms info in a single xml file. But while importing the xml file with import function like below:

function ImportAlarm {

Connect-VIServer $serverToImportTo -User 'xxxx'-Password 'xxxx'
$deserializedAlarmInfo = Import-Clixml -Path $fileName
$importedAlarmInfo = ConvertFromDeserialized( $deserializedAlarmInfo )
$entity = Get-Folder -NoRecursion
$alarmManager = Get-View -Id "AlarmManager"
$alarmManager.CreateAlarm($entity.Id, $importedAlarmInfo)
}

I did not edit the ConvertFromDeserialized function.While importing, I am getting an error saying

Please find the complete error in the attachment.

Could you please guide me on how to export/import all alarms to/from a single xml file rather than a folder having xml file for each alarm. If there are any limitations, please let me know. Thanks a lot for all your help.
