function Invoke-IntuneRestoreDeviceConfigurationAssignment { <# .SYNOPSIS Restore Intune Device Configuration Assignments .DESCRIPTION Restore Intune Device Configuration Assignments from JSON files per Device Configuration Policy from the specified Path. .PARAMETER Path Root path where backup files are located, created with the Invoke-IntuneBackupDeviceConfigurationAssignment 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-IntuneRestoreDeviceConfigurationAssignment -Path "C:\temp" -RestoreById $true #> [CmdletBinding()] param( [Parameter(Mandatory = $true)] [string]$Path, [Parameter(Mandatory = $false)] [bool]$RestoreById = $false ) # Get all policies with assignments $deviceConfigurations = Get-ChildItem -Path "$Path\Device Configurations\Assignments" foreach ($deviceConfiguration in $deviceConfigurations) { $deviceConfigurationAssignments = Get-Content -Path $deviceConfiguration.FullName | ConvertFrom-Json $deviceConfigurationId = ($deviceConfigurationAssignments[0]).id.Split("_")[0] # Create the base requestBody $requestBody = @{ deviceConfigurationGroupAssignments = @() assignments = @() } # Add assignments to restore to the request body foreach ($deviceConfigurationAssignment in $deviceConfigurationAssignments) { $deviceConfigurationAssignmentId = ($deviceConfigurationAssignments[0]).id.Split("_")[1] # If group assignment if ($deviceConfigurationAssignment.target."@odata.type" -eq "#microsoft.graph.groupAssignmentTarget") { $requestBody.deviceConfigurationGroupAssignments += @{ "@odata.type" = "#microsoft.graph.deviceConfigurationGroupAssignment" targetGroupId = $deviceConfigurationAssignment.target.groupId } } # If exclusion group assignment if ($deviceConfigurationAssignment.target."@odata.type" -eq "#microsoft.graph.exclusionGroupAssignmentTarget") { $requestBody.deviceConfigurationGroupAssignments += @{ "@odata.type" = "#microsoft.graph.deviceConfigurationGroupAssignment" targetGroupId = $deviceConfigurationAssignment.target.groupId excludeGroup = $true } } # If 'All users' assignment if ($deviceConfigurationAssignment.target."@odata.type" -eq "#microsoft.graph.allLicensedUsersAssignmentTarget") { $deviceConfigurationAssignmentId = ($deviceConfigurationAssignments[0]).id.Split("_")[1] $requestBody.assignments += @{ "@odata.type" = "#microsoft.graph.deviceConfigurationAssignment" id = $deviceConfigurationAssignmentId target = @{ "@odata.type" = "#microsoft.graph.allLicensedUsersAssignmentTarget" } } } # If 'All Devices' assignment if ($deviceConfigurationAssignment.target."@odata.type" -eq "#microsoft.graph.allDevicesAssignmentTarget") { $deviceConfigurationAssignmentId = ($deviceConfigurationAssignments[0]).id.Split("_")[1] $requestBody.assignments += @{ "@odata.type" = "#microsoft.graph.deviceConfigurationAssignment" id = $deviceConfigurationAssignmentId target = @{ "@odata.type" = "#microsoft.graph.allDevicesAssignmentTarget" } } } } # Filter empty keys from HashTable, because mixing group and all users/devices assignments don't play along very well. if (-not ($requestBody.assignments)) { $requestBody.Remove('assignments') } elseif (-not ($requestBody.deviceConfigurationGroupAssignments)) { $requestBody.Remove('deviceConfigurationGroupAssignments') } # Convert the PowerShell object to JSON $requestBody = $requestBody | ConvertTo-Json -Depth 3 # Get the Device Configuration we are restoring the assignments for try { if ($RestoreById) { $deviceConfigurationObject = Get-GraphDeviceConfiguration -Id $deviceConfigurationId } else { $deviceConfigurationObject = Get-GraphDeviceConfiguration | Where-Object displayName -eq "$($deviceConfiguration.BaseName)" if (-not ($deviceConfigurationObject)) { Write-Warning "Error retrieving Intune Device Configuration for $($deviceConfiguration.FullName).
