function Invoke-IntuneRestoreDeviceManagementScriptAssignment { <# .SYNOPSIS Restore Intune Device Management Script Assignments .DESCRIPTION Restore Intune Device Management Script Assignments from JSON files per Device Management Script from the specified Path. .PARAMETER Path Root path where backup files are located, created with the Invoke-IntuneBackupDeviceManagementScriptAssignment function .PARAMETER RestoreById If RestoreById is set to true, assignments will be restored to Intune Device Management Scripts that match the id. If RestoreById is set to false, assignments will be restored to Intune Device Management Scripts that match the file name. This is necessary if the Device Management Script was restored from backup, because then a new Device Management Script is created with a new unique ID. .EXAMPLE Invoke-IntuneRestoreDeviceManagementScriptAssignment -Path "C:\temp" -RestoreById $true #> [CmdletBinding()] param( [Parameter(Mandatory = $true)] [string]$Path, [Parameter(Mandatory = $false)] [bool]$RestoreById = $false, [Parameter(Mandatory = $false)] [ValidateSet("v1.0", "Beta")] [string]$ApiVersion = "Beta" ) # Set the Microsoft Graph API endpoint if (-not ((Get-MSGraphEnvironment).SchemaVersion -eq $apiVersion)) { Update-MSGraphEnvironment -SchemaVersion $apiVersion -Quiet Connect-MSGraph -ForceNonInteractive -Quiet } # Get all policies with assignments $deviceManagementScripts = Get-ChildItem -Path "$Path\Device Management Scripts\Assignments" foreach ($deviceManagementScript in $deviceManagementScripts) { $deviceManagementScriptAssignments = Get-Content -LiteralPath $deviceManagementScript.FullName | ConvertFrom-Json $deviceManagementScriptId = ($deviceManagementScriptAssignments[0]).id.Split(":")[0] # Create the base requestBody $requestBody = @{ deviceManagementScriptAssignments = @() } # Add assignments to restore to the request body foreach ($deviceManagementScriptAssignment in $deviceManagementScriptAssignments) { $requestBody.deviceManagementScriptAssignments += @{ "target" = $deviceManagementScriptAssignment.target } } # Convert the PowerShell object to JSON $requestBody = $requestBody | ConvertTo-Json -Depth 100 # Get the Device Management Script we are restoring the assignments for try { if ($restoreById) { $deviceManagementScriptObject = Invoke-MSGraphRequest -HttpMethod GET -Url "deviceManagement/deviceManagementScripts/$deviceManagementScriptId" } else { $deviceManagementScriptObject = Invoke-MSGraphRequest -HttpMethod GET -Url "deviceManagement/deviceManagementScripts" | Get-MSGraphAllPages | Where-Object displayName -eq "$($deviceManagementScript.BaseName)" if (-not ($deviceManagementScriptObject)) { Write-Verbose "Error retrieving Intune Device Management Script for $($deviceManagementScript.FullName).
