function Invoke-IntuneRestoreDeviceCompliancePolicyAssignment { <# .SYNOPSIS Restore Intune Device Compliance Policy Assignments .DESCRIPTION Restore Intune Device Compliance Policy Assignments from JSON files per Device Compliance Policy from the specified Path. .PARAMETER Path Root path where backup files are located, created with the Invoke-IntuneBackupDeviceCompliancePolicyAssignment 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-IntuneRestoreDeviceCompliancePolicyAssignment -Path "C:\temp" -RestoreById $true #> [CmdletBinding()] param( [Parameter(Mandatory = $true)] [string]$Path, [Parameter(Mandatory = $false)] [bool]$RestoreById = $false ) # Get all policies with assignments $deviceCompliancePolicies = Get-ChildItem -Path "$Path\Device Compliance Policies\Assignments" foreach ($deviceCompliancePolicy in $deviceCompliancePolicies) { $deviceCompliancePolicyAssignments = Get-Content -Path $deviceCompliancePolicy.FullName | ConvertFrom-Json $deviceCompliancePolicyId = ($deviceCompliancePolicyAssignments[0]).id.Split("_")[0] # Create the base requestBody $requestBody = @{ assignments = @() } # Add assignments to restore to the request body foreach ($deviceCompliancePolicyAssignment in $deviceCompliancePolicyAssignments) { $deviceCompliancePolicyAssignmentId = ($deviceCompliancePolicyAssignments[0]).id.Split("_")[1] # If group assignment if ($deviceCompliancePolicyAssignment.target."@odata.type" -eq "#microsoft.graph.groupAssignmentTarget") { $requestBody.assignments += @{ target = @{ "@odata.type" = "#microsoft.graph.groupAssignmentTarget" groupId = $deviceCompliancePolicyAssignment.target.groupId } } } # If exclusion group assignment if ($deviceCompliancePolicyAssignment.target."@odata.type" -eq "#microsoft.graph.exclusionGroupAssignmentTarget") { $requestBody.assignments += @{ target = @{ "@odata.type" = "#microsoft.graph.exclusionGroupAssignmentTarget" groupId = $deviceCompliancePolicyAssignment.target.groupId } } } # If 'All users' assignment if ($deviceCompliancePolicyAssignment.target."@odata.type" -eq "#microsoft.graph.allLicensedUsersAssignmentTarget") { $deviceCompliancePolicyAssignmentId = ($deviceCompliancePolicyAssignments[0]).id.Split("_")[1] $requestBody.assignments += @{ "@odata.type" = "#microsoft.graph.deviceCompliancePolicyAssignment" id = $deviceCompliancePolicyAssignmentId target = @{ "@odata.type" = "#microsoft.graph.allLicensedUsersAssignmentTarget" } } } # If 'All Devices' assignment if ($deviceCompliancePolicyAssignment.target."@odata.type" -eq "#microsoft.graph.allDevicesAssignmentTarget") { $deviceCompliancePolicyAssignmentId = ($deviceCompliancePolicyAssignments[0]).id.Split("_")[1] $requestBody.assignments += @{ "@odata.type" = "#microsoft.graph.deviceCompliancePolicyAssignment" id = $deviceCompliancePolicyAssignmentId target = @{ "@odata.type" = "#microsoft.graph.allDevicesAssignmentTarget" } } } } # Convert the PowerShell object to JSON $requestBody = $requestBody | ConvertTo-Json -Depth 3 # Get the Device Compliance Policy we are restoring the assignments for try { if ($RestoreById) { $deviceCompliancePolicyObject = Get-GraphDeviceCompliancePolicy -Id $deviceCompliancePolicyId } else { $deviceCompliancePolicyObject = Get-GraphDeviceCompliancePolicy | Where-Object displayName -eq "$($deviceCompliancePolicy.BaseName)" if (-not ($deviceCompliancePolicyObject)) { Write-Warning "Error retrieving Intune Compliance Policy for $($deviceCompliancePolicy.FullName).
