Compare Management Packs version on 2 management groups

The Following powershell script help you to compare management packs from 2 environments (like prod and preprod env).


In argument of the script:

1. RMS Name of the 1st Management Group
2. RMS Name of the 2nd Management Group
3. Name of the csv file

Here is the script:

param([string]$ref, [string]$diff, [String]$csvfile)

function Connect-OpsMgr ([string] $rootMS ) {

#Initializing the Ops Mgr 2007 Powershell provider
 if ( (Get-pssnapin | where {$_.Name -eq "Microsoft.EnterpriseManagement.OperationsManager.Client" }).Name -ne "Microsoft.EnterpriseManagement.OperationsManager.Client" ) {
  add-pssnapin "Microsoft.EnterpriseManagement.OperationsManager.Client" -ErrorVariable errSnapin; }
 Set-Location "OperationsManagerMonitoring::" -ErrorVariable errSnapin;
 $CS = Gwmi Win32_ComputerSystem -Comp "."
 
 #$cred=get-credential $CS.Username
 
 $mg=New-ManagementGroupConnection -ConnectionString:$rootMS -Credential:$cred -ErrorVariable errSnapin;
 Set-Location $rootMS -ErrorVariable errSnapin;
 
 #Checks to see if it failed or succedded in loading the provider
 if ($errSnapin.count -ne 0)
  {   
   Write-Output "OpsMgr 2007 PSSnapin failed initialize!"
   Write-Output "Please verify you are running this script on a computer that have the console installed" 
   Write-Output "Instance Maintenance Mode failed due:`nPowershell was not able to connect to OpsMgr platform.`nImpossible to put in mainteance mode the object [$Computer]::$object.`nContact SP Windows to reinstall the powershell and the OpsMgr console" "MaintenanceMode" "Error" 1000
  
  }
}
