Automating Intune App Deployments with PowerShell: Step-by-step scripts for SCCM-Intune hybrid workflows

PowerShell automation bridges SCCM and Intune in hybrid environments, enabling bulk Win32 app migrations with Microsoft Graph API for co-managed workloads.

Key Advantages

Bulk app migrations preserve SCCM metadata like publisher/version, enabling compliance tracking in Intune without manual re-entry. Graph API eliminates portal throttling, supporting 100+ apps/hour versus GUI limits; PSADT integration ensures robust detection across hybrid-joined fleets.

Use Case

Large enterprises consolidate SCCM (10k+ apps) into Intune during hybrid migrations, targeting zero-touch Autopilot rollouts. Finance teams mandate app rationalization: eliminate 40% duplicate apps via SCCM export analysis, deploy 2k critical apps to global sites within 48 hours cutover. IT ops shifts from ticket-driven installs to self-service catalogs, dropping support calls 65% while enabling ServiceNow integration for approval workflows

Complete Delivery Framework

Phase 1: SCCM Assessment and Packaging

# SCCM Server: Export deployable apps

Import-Module ConfigurationManager

Set-Location "PS1:"

$DeployedApps = Get-CMApplication | Where-Object {$_.IsDeployed -and $_.DeployActionType -eq "Install"} |

Select-Object LocalizedDisplayName, Publisher, SoftwareVersion, @{N="ContentPath";E={$_.Deployments[0].ContentLocation}}

$DeployedApps | Export-Csv "SCCM_App_Inventory.csv" -NoTypeInformation

# Local: Batch package .intunewin (loop via CSV)

$IntuneWinTool = "IntuneWinAppUtil.exe"

foreach ($App in Import-Csv SCCM_App_Inventory.csv) {

& $IntuneWinTool -c $App.ContentPath -s "*.msi" -o ".\IntuneWin\$($App.LocalizedDisplayName)\"

}

Rationalize: Filter vendor duplicates, standardize PSADT wrappers for 95% detection success.

Phase 2: Intune Graph Automation

# Install modules & auth

Install-Module Microsoft.Graph.DeviceManagementApps -Force

Connect-MgGraph -Scopes "DeviceManagementApps.ReadWrite.All","Group.ReadWrite.All"

# Bulk Win32 app creation + upload

$AppTemplate = @{

"@odata.type" = "#microsoft.graph.win32LobApp"

displayName = "{AppName}"

publisher = "{Publisher}"

fileName = "{IntuneWinFile}"

size = 0 # Auto-populate

installCommandLine = "Deploy-Application.exe -DeploymentType Install -DeployMode Silent"

uninstallCommandLine = "Deploy-Application.exe -DeploymentType Uninstall"

detectionRules = @(

@{

"@odata.type" = "#microsoft.graph.win32LobAppRegistryDetection"

registryPath = "HKLM\SOFTWARE\Microsoft\AppDeployToolkit\Deployments\{AppName}"

registryType = "integer"

operator = "exists"

valueData = "1"

}

)

}

foreach ($App in Import-Csv SCCM_App_Inventory.csv) {

$Template = $AppTemplate.Clone()

$Template.displayName = $App.LocalizedDisplayName

$Template.publisher = $App.Publisher

$AppJson = $Template | ConvertTo-Json -Depth 10

# Create app shell

$NewApp = New-MgDeviceManagementMobileApp -BodyParameter $AppJson

# Upload .intunewin content (Graph PATCH - requires custom function)

Upload-IntuneWinContent -AppId $NewApp.Id -FilePath ".\IntuneWin\$($App.LocalizedDisplayName)\*.intunewin"

# Phased assignment: Pilot > Production

$PilotAssignment = @{

intent = "available"

target = @{ "@odata.type" = "#microsoft.graph.groupAssignmentTarget"; groupId = "pilot-hybrid-group-guid" }

}

New-MgDeviceAppManagementMobileAppAssignment -MobileAppId $NewApp.Id -BodyParameter $PilotAssignment

}

Zero-day validation: 100% pilot success before Required assignment.

Capability Building Program

Role	Training Module
L1 Ops	Read-only Graph queries; app install troubleshooting via IME logs
L2 Admins	Modify detection rules; create dynamic groups; Azure Automation runbooks
Architects	Full pipeline ownership; ServiceNow Graph integration; cost optimization

Hands-On Labs (4-week program):

1. Week 1: SCCM export + .intunewin packaging (20 apps)

2. Week 2: Graph app creation + pilot deployments

3. Week 3: Monitoring dashboards + failure recovery

4. Week 4: Production cutover + supersedence migration

   
   

Metrics Dashboard (Power BI integration):

# Export for Power BI

Get-MgDeviceAppManagementMobileApp | Select-Object DisplayName, @{N="InstallSuccess";E={

(Get-MgDeviceAppManagementMobileAppDeviceStatuses -MobileAppId $_.Id |

Where-Object {$_.InstallState -eq "installed"}).Count

}} | Export-Csv "App_Deployment_Metrics.csv"

Enables self-service ops: L1 handles 80% app issues independently post-training.

Metric	Before	After	Improvement
App Deploy Time	4 weeks/100 apps	4 hours/100 apps	95% faster ​
Support Tickets	500/month	175/month	65% reduction
Admin Capacity	3 FTEs	1 FTE + automation	67% efficiency

Production deployments handle 5k+ apps across 50k endpoints; GitHub repo with pre-built pipelines accelerates future migrations 10x.
