Intune Group Policy Analytics Migration Checklist for Central Valley IT Teams

How should a Modesto business use Intune Group Policy Analytics before moving endpoint management to the cloud?

A Modesto business should use Intune Group Policy Analytics to inventory existing Group Policy Objects, identify which settings can move to Microsoft Intune, separate unsupported or deprecated settings, and build a controlled migration plan before assigning policies to production devices. The goal is not to copy every GPO into Intune. The goal is to modernize endpoint management without breaking authentication, security, printing, line-of-business apps, or compliance evidence.

For many Central Valley organizations, the endpoint environment has grown in layers: Active Directory, inherited GPOs, VPN dependencies, shared workstations, remote users, Microsoft 365, aging Windows 10 devices, and partial cloud adoption. That mix is normal. It is also exactly why a clean Intune migration should start with analysis, not guesswork.

Microsoft’s Group Policy analytics feature is built for this first step. It lets administrators import on-premises GPO data, analyze which settings have modern mobile device management equivalents, identify deprecated or unsupported settings, and use those findings to create Intune Settings Catalog policies where appropriate.¹ Used correctly, it becomes both a migration tool and a risk-reduction worksheet.

That matters now because Windows 10 reached end of support on October 14, 2025, and Microsoft states that affected editions no longer receive security updates after that date unless an organization has a valid path such as upgrade, replacement, or Extended Security Updates.² Even when a business still has Windows 10 devices enrolled in Intune, endpoint management should be treated as a transition state, not a stable long-term design.

For Datapath’s clients in Modesto, Fresno, Modesto, and surrounding markets, the practical question is usually not “Should we use Intune?” It is “How do we move without losing the controls our legacy environment still depends on?”

Why Group Policy Analytics should come before Intune policy deployment

Group Policy Analytics should come before broad Intune deployment because legacy GPOs often contain years of undocumented operational decisions. Some settings enforce real security requirements. Some exist only because an old application needed them. Some conflict with modern security baselines. Some no longer apply at all.

Skipping analysis creates three predictable problems:

• Security policies get duplicated across GPO, Intune, Defender, and local configuration.
• Devices receive conflicting instructions, creating inconsistent compliance results.
• IT loses the audit trail needed to explain why a setting changed, stayed, or was retired.

Microsoft describes Group Policy analytics as a way to import and analyze on-premises GPOs, see which settings are supported by cloud-based MDM providers such as Intune, identify deprecated or unavailable settings, and migrate imported GPOs into Settings Catalog policies where supported.¹ That is useful, but it should not be treated as an automatic “lift and shift” button.

A good migration separates settings into four buckets:

1. Move to Intune as-is because the setting is supported and still needed.
2. Move with redesign because the security intent is valid but the old implementation is obsolete.
3. Replace with a baseline or modern control because Microsoft Defender, Windows security baselines, Conditional Access, or endpoint compliance policies handle it better.
4. Retire because the setting is unused, risky, unsupported, or tied to decommissioned infrastructure.

This is where an MSP or co-managed IT partner earns its keep. The tool can identify technical supportability. It cannot decide business impact, maintenance windows, clinical workflow risk, accounting system dependencies, or user disruption.

Step 1: Export and inventory the GPOs that actually matter

The first step is to build a controlled inventory of GPOs before importing anything into Intune analytics. Do not start with every stale object in Active Directory. Start with GPOs linked to active organizational units, production users, production workstations, shared workstations, servers if in scope, and high-risk groups.

For each GPO, capture:

• GPO name
• Linked OU or security filtering
• Target users or devices
• Business owner, if known
• Last modified date
• Whether it affects security, identity, networking, browser settings, Office, printers, mapped drives, scripts, or application compatibility
• Whether the GPO is still applied to active devices
• Known help desk issues or exceptions tied to the policy

The inventory stage should also identify “tribal knowledge” GPOs. These are policies no one wants to touch because “something broke last time.” They deserve special handling, not blind migration.

For a Central Valley healthcare clinic, that might include scanner software, EHR printing, shared exam-room PCs, badge workflows, or browser compatibility settings. For a financial firm, it might include mapped drives, document management integrations, encryption settings, or legacy line-of-business apps. For a K-12 environment, it might include student device restrictions, testing browser requirements, printer mappings, and Wi-Fi certificate settings.

Step 2: Import GPO XML files into Group Policy Analytics

Once the inventory is narrowed, export the relevant GPOs as XML and import them into Microsoft Intune Group Policy analytics. The analysis will show which settings are supported by MDM, which are deprecated, and which are unavailable for Intune migration.¹

The output should be reviewed by policy family, not just by percentage migrated. A GPO with “high support” can still contain one unsupported setting that matters operationally. A GPO with “low support” may still contain a few critical security requirements that should be rebuilt another way.

Group results into categories such as:

• Windows security settings
• Microsoft Defender settings
• BitLocker and encryption
• Firewall rules
• Browser policies
• Office policies
• Credential and authentication policies
• Local administrator controls
• Power management
• Windows Update behavior
• Scripts, mapped drives, and printers
• Legacy Internet Explorer or compatibility settings
• Application-specific settings

This lets the migration team separate security posture from convenience settings. Security controls should be governed. Convenience settings should be challenged. Legacy settings should have an owner and an expiration date.

Step 3: Compare legacy settings against Intune security baselines

After analytics, compare the legacy settings against Microsoft Intune security baselines. Microsoft describes Intune security baselines as groups of preconfigured Windows settings intended to apply recommended security posture to managed Windows devices.³

This comparison matters because many organizations have old GPOs that were once “secure enough” but no longer reflect modern Microsoft 365 risk. For example, a legacy environment may have local firewall rules, weak browser settings, inconsistent BitLocker enforcement, stale Office macros policy, or old administrative templates that do not align with current Defender and Windows recommendations.

Do not assume Microsoft baselines should be accepted without review. Microsoft itself notes that default baseline values can be restrictive and should be checked for conflicts with other policy settings or environmental requirements.³ In practice, that means each baseline should go through a pilot before broad assignment.

A disciplined process looks like this:

• Start with a test device group.
• Apply one baseline family at a time.
• Check conflicts in Intune reporting.
• Validate sign-in, printing, VPN, EHR, ERP, accounting, browser, and productivity workflows.
• Document exceptions with owners and expiration dates.
• Move only stable settings into production rings.

For regulated organizations, the output should not be “we enabled the baseline.” The output should be evidence: what changed, why it changed, who approved it, where exceptions exist, and how compliance will be monitored.

Step 4: Apply security-focused configuration management discipline

Intune migration is a configuration management project, not just an endpoint project. NIST SP 800-128 frames security-focused configuration management as a process for establishing and maintaining secure configurations, controlling configuration changes, monitoring configuration status, and supporting security impact analysis.⁴

That guidance is directly relevant to Intune migrations because every endpoint policy can affect user access, application behavior, data protection, and incident response. Treating Intune policies as quick admin-console changes creates long-term drift.

For each migrated or redesigned policy, capture:

• Business reason for the setting
• Security objective
• Source GPO or source requirement
• Intune policy name
• Assignment group
• Pilot group
• Rollout ring
• Expected user impact
• Rollback plan
• Exception process
• Evidence location
• Review date

The change record should also indicate whether the setting is mandatory, preferred, transitional, or deprecated. That distinction prevents a temporary workaround from becoming permanent architecture.

Step 5: Build migration rings instead of a single cutover

A safe Intune migration uses deployment rings. A risky migration assigns policies broadly and waits for tickets.

Recommended rings:

1. Lab devices: IT-owned test machines with no production dependency.
2. IT pilot: Help desk, systems administrators, and security stakeholders.
3. Friendly users: A small cross-section of departments with known workflows.
4. Department pilot: One business unit at a time.
5. Broad production: Remaining eligible devices after issue patterns are resolved.
6. Exception group: Devices or users with documented blockers.

Each ring should have success criteria before the next ring begins. Examples include:

• Device checks in successfully.
• Policy conflict rate is understood and decreasing.
• BitLocker recovery key escrow is verified.
• Defender status reports correctly.
• Required applications launch.
• VPN or remote access works.
• Printing and scanning work where needed.
• Browser-based business apps work.
• Help desk tickets are categorized and resolved.
• Exceptions are documented.

This ring structure is especially important for multi-site organizations in Modesto, Fresno, Modesto because endpoint behavior may differ by office, network, department, and device age.

Step 6: Decide what not to migrate

The hardest part of a GPO-to-Intune migration is deciding what not to carry forward. Old policies often encode assumptions that are no longer true.

Do not migrate a setting simply because it exists. Retire or redesign settings that are:

• Tied to decommissioned servers
• Dependent on legacy VPN paths
• Required only by retired software
• Redundant with Intune security baselines
• Redundant with Defender policies
• Duplicated across multiple GPOs
• Unowned by any business or technical stakeholder
• In conflict with Windows 11 readiness
• Inconsistent with least privilege
• Impossible to monitor cleanly

CISA’s Cross-Sector Cybersecurity Performance Goals are useful as a prioritization lens because they are designed to help small and medium-sized organizations focus on high-impact practices with risk-reduction value.⁵ For endpoint policy work, that means prioritizing controls that improve asset visibility, identity protection, secure configuration, vulnerability reduction, detection, response, and recovery.

A clean Intune environment is not the environment with the most policies. It is the environment where every policy has a reason, an owner, an assignment scope, a monitoring method, and a review cycle.

Step 7: Preserve evidence for executives, auditors, and cyber insurance

An Intune migration can generate useful evidence if the project is structured correctly. That evidence can support executive reporting, cyber insurance renewal, compliance reviews, and incident response readiness.

Keep evidence for:

• GPO inventory and migration status
• Unsupported or deprecated settings
• Policy decisions and approvals
• Pilot results
• Security baseline assignments
• Exceptions and compensating controls
• Device compliance reports
• Encryption status
• Defender onboarding status
• Local admin control decisions
• Rollback tests
• Final production assignment groups

For regulated organizations, screenshots alone are weak evidence. Better evidence includes exported reports, change tickets, policy names, assignment groups, dates, owners, exception registers, and review notes.

This is also where Datapath’s accountability model fits the actual business problem. Most organizations do not need a giant theoretical endpoint transformation. They need a clear plan, clean execution, documented exceptions, and a partner who will keep the configuration from drifting six months later.

What should the finished Intune migration package include?

The finished package should include an executive summary, a technical migration workbook, a policy inventory, a baseline comparison, rollout evidence, exception documentation, and a monitoring plan. It should be understandable to leadership without losing the technical detail needed by IT.

A practical final package includes:

• Executive summary: What moved, what changed, what risk was reduced, what remains.
• GPO disposition table: Migrate, redesign, replace, retire, or defer.
• Intune policy map: Old GPO to new Intune policy or replacement control.
• Baseline decision log: Accepted, customized, rejected, or deferred baseline settings.
• Pilot evidence: Device groups, issue findings, remediation notes.
• Production rollout log: Dates, groups, success criteria.
• Exception register: Owner, reason, compensating control, expiration date.
• Monitoring plan: Compliance reports, review cadence, alerting, and ownership.
• Rollback plan: What to disable, who approves, and how recovery is verified.

For a growing business, this package is often more valuable than the technical migration itself. It converts endpoint management from inherited sprawl into a governed operating model.

When should a business get outside help?

A business should get outside help when its GPOs are undocumented, when internal IT does not have time to test business workflows, when regulated data is involved, when Windows 10 replacement overlaps with Microsoft 365 security work, or when executives need evidence that the migration reduced risk.

Outside help is especially useful when the environment includes:

• Multiple offices
• Remote or hybrid staff
• Legacy Active Directory dependencies
• Windows 10 and Windows 11 mixed fleets
• Healthcare, finance, education, or government workflows
• Shared workstations
• Specialized printers, scanners, or line-of-business apps
• Cyber insurance evidence requirements
• Limited internal security staff

Datapath helps organizations modernize endpoint management through practical planning, implementation, documentation, and ongoing accountability.

FAQ

What is Intune Group Policy Analytics?

Intune Group Policy Analytics is a Microsoft Intune feature that lets administrators import exported on-premises GPOs, analyze whether settings are supported by cloud-based MDM, identify deprecated or unavailable settings, and migrate supported settings into Intune Settings Catalog policies where appropriate.

Should we migrate every GPO into Intune?

No. Migrating every GPO usually recreates legacy complexity in a new platform. Each GPO should be reviewed and classified as migrate, redesign, replace, retire, or defer. Unsupported settings, stale application settings, duplicate policies, and unowned exceptions should not be carried forward blindly.

Can Microsoft Intune replace Active Directory Group Policy?

In many endpoint management scenarios, Intune can replace or reduce dependence on traditional Group Policy, especially for cloud-native Windows devices. The right answer depends on device state, application dependencies, identity architecture, network requirements, and whether unsupported GPO settings need redesign or replacement.

How does Windows 10 end of support affect Intune planning?

Windows 10 end of support increases urgency because unsupported devices no longer receive standard security updates after October 14, 2025, unless covered by an appropriate option. Intune migration should be coordinated with Windows 11 readiness, device replacement, security baselines, and application compatibility testing.

Are Intune security baselines enough by themselves?

No. Intune security baselines are a strong starting point, but they still require testing, customization, exception management, and monitoring. Microsoft notes that baseline defaults can be restrictive and should be reviewed for conflicts. Baselines should be part of a governed endpoint strategy, not the whole strategy.

What evidence should we keep after a GPO-to-Intune migration?

Keep the original GPO inventory, migration decisions, Intune policy map, pilot results, baseline comparison, exception register, assignment groups, compliance reports, rollback plan, and approval records. This evidence helps with executive reporting, compliance reviews, cyber insurance, and future troubleshooting.
