Update the content path of all Applications in ConfigMgr 2012 with PowerShell

If you’ve been dealing with PowerShell and ConfigMgr 2012 lately, you’ve probably found out that the most interesting properties of an application is stored in XML format in the SDMPackageXML property. On of the properties that is stored in SDMPackageXML under DeploymentTypes is the Contents. The value of Contents is the one you’d modify in order to change the path of an applications contents. The script below will do just this, but for all applications and only the latest version.

The script

[System.Reflection.Assembly]::LoadFrom((Join-Path (Get-Item $env:SMS_ADMIN_UI_PATH).Parent.FullName "Microsoft.ConfigurationManagement.ApplicationManagement.dll")) | Out-Null
[System.Reflection.Assembly]::LoadFrom((Join-Path (Get-Item $env:SMS_ADMIN_UI_PATH).Parent.FullName "Microsoft.ConfigurationManagement.ApplicationManagement.Extender.dll")) | Out-Null
[System.Reflection.Assembly]::LoadFrom((Join-Path (Get-Item $env:SMS_ADMIN_UI_PATH).Parent.FullName "Microsoft.ConfigurationManagement.ApplicationManagement.MsiInstaller.dll")) | Out-Null
$SiteServer = "<name_of_your_Primary_Site_server>"
$SiteCode = "<your_site_code>"
$CurrentContentPath = "\\\\<name_of_server_where_the_content_was_stored_previously\\<folder>\\<folder>"
$UpdatedContentPath = "\\<name_of_the_server_where_the_content_is_stored_now\<folder>\<folder>"
$Applications = Get-WmiObject -ComputerName $SiteServer -Namespace root\SMS\site_$SiteCode -class SMS_Application | Where-Object {$_.IsLatest -eq $True}
$ApplicationCount = $Applications.Count
Write-Output ""
Write-Output "INFO: A total of $($ApplicationCount) applications will be modified`n"
Write-Output "INFO: Value of current content path: $($CurrentContentPath)"
Write-Output "INFO: Value of updated content path: $($UpdatedContentPath)`n"
Write-Output "# What would you like to do?"
Write-Output "# ---------------------------------------------------------------------"
Write-Output "# 1. Verify first - Verify the applications new path before updating"
Write-Output "# 2. Update now - Update the path on all applications"
Write-Output "# ---------------------------------------------------------------------`n"
$EnumAnswer = Read-Host "Please enter your selection [1,2] and press Enter"
switch ($EnumAnswer) {
    1 {$SetEnumAnswer = "Verify"}
    2 {$SetEnumAnswer = "Update"}
    Default {$SetEnumAnswer = "Verify"}
}
if ($SetEnumAnswer -like "Verify") {
    Write-Output ""
    $Applications | ForEach-Object {
        $CheckApplication = [wmi]$_.__PATH
        $CheckApplicationXML = [Microsoft.ConfigurationManagement.ApplicationManagement.Serialization.SccmSerializer]::DeserializeFromString($CheckApplication.SDMPackageXML,$True)
        foreach ($CheckDeploymentType in $CheckApplicationXML.DeploymentTypes) {
            $CheckInstaller = $CheckDeploymentType.Installer
            $CheckContents = $CheckInstaller.Contents[0]
            $CheckUpdatedPath = $CheckContents.Location -replace "$($CurrentContentPath)","$($UpdatedContentPath)"
            Write-Output "INFO: Current content path for $($_.LocalizedDisplayName):"
            Write-Host -ForegroundColor Green "$($CheckContents.Location)"
            Write-Output "UPDATE: Updated content path will be:"
            Write-Host -ForegroundColor Red "$($CheckUpdatedPath)`n"
        }
    }
}
if ($SetEnumAnswer -like "Update") {
    Write-Output ""
    $Applications | ForEach-Object {
        $Application = [wmi]$_.__PATH
        $ApplicationXML = [Microsoft.ConfigurationManagement.ApplicationManagement.Serialization.SccmSerializer]::DeserializeFromString($Application.SDMPackageXML,$True)
        foreach ($DeploymentType in $ApplicationXML.DeploymentTypes) {
            $Installer = $DeploymentType.Installer
            $Contents = $Installer.Contents[0]
            $UpdatePath = $Contents.Location -replace "$($CurrentContentPath)","$($UpdatedContentPath)"
            if ($UpdatePath -ne $Contents.Location) {
                $UpdateContent = [Microsoft.ConfigurationManagement.ApplicationManagement.ContentImporter]::CreateContentFromFolder($UpdatePath)
                $UpdateContent.FallbackToUnprotectedDP = $True
                $UpdateContent.OnFastNetwork = [Microsoft.ConfigurationManagement.ApplicationManagement.ContentHandlingMode]::Download
                $UpdateContent.OnSlowNetwork = [Microsoft.ConfigurationManagement.ApplicationManagement.ContentHandlingMode]::DoNothing
                $UpdateContent.PeerCache = $False
                $UpdateContent.PinOnClient = $False
                $Installer.Contents[0].ID = $UpdateContent.ID
                $Installer.Contents[0] = $UpdateContent
            }
        }
        $UpdatedXML = [Microsoft.ConfigurationManagement.ApplicationManagement.Serialization.SccmSerializer]::SerializeToString($ApplicationXML, $True)
        $Application.SDMPackageXML = $UpdatedXML
        $Application.Put() | Out-Null
        Write-Output "INFO: Updated content path for $($_.LocalizedDisplayName)"
    }
}

Using the script

In order to use this script, save it as e.g. Update-ApplicationSource.ps1 and save it to a folder e.g. E:\Scripts as I’ve done in the pictures below. The script has 2 functions. The first function is to verify what will be changed and the second is to update the Contents property value. For it to work in your environment, you’d need to change four variables:

• $SiteServer = “<name_of_your_Primary_Site_server>“
• $SiteCode = “<your_site_code>“
• $CurrentContentPath = “\\\\<name_of_server_where_the_content_was_stored_previously\\<folder>\\<folder>“
• $UpdatedContentPath = “\\<name_of_the_server_where_the_content_is_stored_now\<folder>\<folder>“

When you’ve modified the script to work in your environment, do the following to run it:
1. Open an elevated PowerShell command prompt.
2. Browse to where you saved the script.
3. Run the following command:

.\Update-ApplicationSource.ps1

4. You’ll be asked to enter 1 or 2. Choose 1 if you’d like to verify what changes will be made. The script will only enumerate all the applications old content path and show you what the changed value would be. I’d recommend that you choose the verify option first and then relaunch the script again when you are confident that everything looks correct.

5. When you’ve verified your applications content path, relaunch the script by running the command above and choose option 2.

The script will now go through all the applications and update the content path. Depending on how many applications you have, the execution time will vary. As you can see I have 162 applications, and it took a couple of minutes for it to complete. As for a convenience, I’ve added so that the script will output what application it’s currently working on and what the current content path is so it doesn’t look like it has stalled.
I hope this helps!
