🔄End-to-end steps for MECM (SCCM) to Intune migration

This sequence walks you from zero to clean decommission, with crisp steps and the smallest details you need to avoid surprises.

🧭 Phase 0: Foundational preparation

1. Confirm licensing and tenant readiness
• Licenses: Intune, Windows E3/E5, Entra ID P1/P2 (for Conditional Access), Defender for Endpoint, and any add-ons.
• Domains: Verify custom domains and federation; align hybrid identity (if used) with HR source systems.
• Access: Establish Intune RBAC roles and scope tags mapped to business units/regions.

2. Baseline device and OS standards
• OS: Standardize to Windows 11 24H2+ or Windows latest;.
• Hardware: Ensure TPM 2.0 and Secure Boot for BitLocker; validate BIOS/UEFI settings; plan firmware updates.

3. Network and endpoints allow-list
• Connectivity: Allow Intune, Autopilot, WinGet, M365 endpoints, and CDNs; configure proxy/PAC exceptions.
• Delivery optimization: Set DO policies for bandwidth-friendly content distribution.

4. Identity & Access Controls
• Conditional Access: Require MFA, block legacy auth, enforce compliant devices.
• Compliance Policies: BitLocker, Secure Boot, Defender, OS minimums.
• Zero Trust: Verify explicitly, least privilege, assume breach.

5. PKI and certificates (if needed)
• Profiles: Plan SCEP/PKCS via NDES with HA; confirm Wi-Fi/VPN templates, lifetimes, CRL distribution.
• Testing: Validate enrollment, renewal, revocation on pilot devices.

6. Inventory and dependency mapping
• Applications: Export MECM apps/packages with install commands, switches, dependencies, detection rules, uninstall steps.
• Policies: List baselines, GPOs, task sequences, collections; tag regulated/critical workloads.
• Third-party tools: Record AV/EDR, VPN, DLP, encryption, drivers—define cloud-native replacements/integrations.

7. Governance and change control
• KPIs: Enrollment %, compliance %, app success %, update currency, BitLocker coverage, helpdesk trend.
• Change windows: Publish timelines, blast radius limits, and rollback paths per workload.
• Training: Upskill IT on Intune profiles, Win32 packaging, Autopilot, reporting, Graph automation.

📝 Phase 1: Enable co-management and tenant attach

1. Ensure MECM client health
• Client: Remediate unhealthy clients, boundary groups, and distribution points; enable CMG for internet devices if needed.
• Collections: Create pilot collections representing hardware, departments, and app complexity.

2. Enable co-management
• Enrollment: Configure automatic MDM enrollment to Intune for eligible devices; scope to pilot first.
• Join state: Start with Hybrid join for existing corporate devices if needed; plan long-term Entra ID Join.

3. Turn on tenant attach
• Insights: Surface MECM devices in Intune for actions and reporting; verify device sync and admin permissions.

4. Guard against policy conflicts
• Mapping: Document overlapping MECM baselines vs Intune equivalents; disable MECM items as Intune takes over.
________________________________________
🔐 Phase 2: Shift core workloads in controlled waves

1. Compliance policies first
• Standards: Require BitLocker, Secure Boot, TPM, minimum OS, password complexity, device risk integration with Defender.
• Conditional Access: Gate M365 and key apps behind device compliance; pilot with champions before broad enforcement.

2. Device configuration profiles
• Settings catalog: Separate profiles by domain (security, UX, network). Keep them modular to avoid monoliths.
• Security baselines: Apply Microsoft Windows/Microsoft Edge baselines; layer custom hardening where needed.

3. Endpoint security
• BitLocker: Silent enable, escrow keys to Azure AD/Intune; set recovery key rotation cadence and report coverage.
• Defender: Onboard to MDE, enable tamper protection, select ASR rules; tune exclusions based on telemetry.
________________________________________
📦 Phase 3: Migrate applications

1. Classify and prioritize
• Buckets: Win32 (line-of-business), MSIX, Microsoft Store/WinGet, web shortcuts, drivers/firmware utilities.
• Critical path: Identify apps needed during provisioning (ESP blocking) vs post-provisioning.

2. Package Win32 apps
• IntuneWin: Use the content prep tool; define install/uninstall commands, detection rules (file/registry), return code mapping.
• Dependencies: Model prerequisites and supersedence; document uninstall/repair scenarios for rollback.

3. Adopt Microsoft Store and WinGet
• Store: Use the new Microsoft Store integration with private catalog controls.
• WinGet: Reference stable IDs, set version pins only where compliance requires; prefer evergreen updates.

4. Target with rings
• Rings: Pilot → early adopters → broad. Use required vs available assignments strategically.
• Conflict control: Unassign MECM deployments once Intune required installs begin; keep rollback packages ready.
________________________________________
🔄 Phase 4: Windows updates and servicing

1. Design update rings
• Pilot/First/Broad: Stagger deadlines and grace periods; enforce active hours and restart policies thoughtfully.
• Quality vs feature: Monthly CUs via rings; feature updates via dedicated policies with deferrals and safeguard holds.

2. Monitor and remediate
• Telemetry: Track update success %, rollback triggers, and device health; use remediation scripts for stuck states.

3. Drivers and firmware
• OEM channels: Prefer OEM cloud update tools or extensions; package critical drivers with strict targeting if needed.
• BIOS: Gate updates by power state/dock/battery; schedule and report compliance.

________________________________________
🚀 Phase 5: Provisioning with Windows Autopilot

1. Register devices
• Hashes: Intake via OEM to tenant or scripted capture; apply group tags for assignment.
• Dynamic groups: Auto-target deployment profiles by tag, model, department, or ownership.

2. Configure deployment profiles
• Join type: Prefer Entra ID Join; use Hybrid join only if absolutely required.
• ESP: Block desktop until core apps/policies install; keep ESP lean—only essential items.

3. Pre-provisioning (white glove)
• Factory stage: Use for large rollouts to reduce user wait times; validate app cache and policy application.

4. Replace imaging
• OOBE: Retire thick images and task sequences; move to Autopilot + WinGet + configuration profiles.
• Break/fix: Keep minimal recovery guidance and USB images for rare cases.

📈 Phase 6: Pilot execution and scale-out waves

1. Run the pilot
• Cohorts: IT, champions, representative devices/apps; include remote and on-prem segments.
• Metrics: ESP duration, app success %, compliance rate, helpdesk tickets, user feedback.

2. Iterate
• Fixes: Resolve policy conflicts, tune app detection, optimize network/proxy routes, adjust ESP scope.

3. Scale
• Waves: Office-based → remote-heavy → regulated/critical. Respect blackout periods (financial close, product launches).
• Controls: Maintain ring sizes and rollback thresholds; communicate clearly at each step.
________________________________________
🧹 Phase 7: Decommission MECM cleanly

1. Readiness check
• Coverage: ≥95% devices Intune-managed; no critical workloads tied to MECM; Autopilot stable; reporting parity achieved.
• Stakeholders: Security, networking, endpoint, and business owners sign-off.

2. Retire workloads
• Disable: Turn off MECM app deployments, baselines, and task sequences; remove on-prem GPOs superseded by Intune.
• Infrastructure: Decommission distribution points/management points; archive the MECM database and backups.

3. Edge cases
• Niche devices: Document exceptions that remain; define a sunset plan and support path.
• CMG: Remove if no longer justified; otherwise isolate with strict scope.
________________________________________
🔁 Phase 8: Post-migration operations and automation

1. Operational dashboards
• Views: Enrollment, compliance drift, app failures, update currency, BitLocker key escrow, Defender exposure.
• Reporting: Export to Log Analytics/Power BI; deliver weekly executive summaries.

2. Proactive remediation
• Scripts: Detect and fix drift (BitLocker off, Defender disabled, registry deviations); track remediation success.

3. Graph automation
• Scale tasks: Bulk assignments, dynamic group maintenance, app version checks against WinGet, key rotations.

4. Continuous hardening
• Zero Trust: Evolve Conditional Access, PAW baselines, sign-in risk policies; run periodic red team/blue team exercises.
________________________________________
⚠️ Pitfalls to avoid (quick flags)

• Policy overlaps: Don’t run identical settings from MECM and Intune; remove duplicates before broad rollout.
• ESP overload: Keep only essentials blocking the desktop; install non-critical apps post-ESP.
• Proxy blocks: Autopilot/Intune endpoints must be allowed; test across all network segments.
• Certificate drift: Align templates and lifetimes; simulate expirations to validate renewal paths.
• Aggressive targeting: Avoid “All devices” with required apps; use rings and dynamic groups.
