On-premises Active Directory to Entra ID, Intune, and Autopilot migration
How BPro Technologies migrated a business off an aging single on-premises domain controller to a cloud-managed endpoint model with Microsoft Entra ID, Intune, Windows Autopilot, staged update rings, and documented handover.

/ Before and after
Before
A company was running on a single aging on-premises Active Directory domain controller: old server hardware approaching end of support, no offsite redundancy, and a growing number of remote staff who struggled to access resources tied to the office network | Group Policy had accumulated years of inconsistent configurations, with many GPOs no longer applying to the devices they targeted.
After
The on-premises domain controller was decommissioned at project close with no remaining on-premises identity dependency | All devices are enrolled in Intune with enforced compliance policies.
/ Delivery timeline
How the work moved from diagnosis to handover
The timeline keeps the proof story readable: current state, design decisions, controlled delivery, then handover evidence.
Diagnose
Mapped the current state, constraints, dependencies, and highest-risk failure points.
Design
Defined the operating model, rollout path, documentation needs, and rollback criteria.
Deliver
Executed the change in controlled phases with stakeholder updates and support coverage.
Handover
Closed with runbooks, access notes, configuration records, and next-step recommendations.
Problem
The Challenge
A company was running on a single aging on-premises Active Directory domain controller: old server hardware approaching end of support, no offsite redundancy, and a growing number of remote staff who struggled to access resources tied to the office network. Group Policy had accumulated years of inconsistent configurations, with many GPOs no longer applying to the devices they targeted. The business had adopted Microsoft 365 but device management had never moved to the cloud. The domain controller was a single point of failure the business had been tolerating for too long, and a hardware failure would have taken the entire environment with it.
Intervention
Our Approach
BPro Technologies began with a full identity modernization audit covering Active Directory user accounts, security group memberships, applied Group Policy Objects, legacy application dependencies, Microsoft 365 administration needs, and the target Entra ID and Intune operating model. Every GPO was mapped to its Microsoft Intune Configuration Profile equivalent before any migration work began, confirming cloud policy coverage on paper first. Microsoft Entra Connect Sync was configured as a bridge during the transition, synchronizing identities to Entra ID while existing devices were progressively migrated. New and replacement devices were enrolled directly through Windows Autopilot: provisioning profiles configured, Enrollment Status Page tuned to apply all compliance and configuration policies before handing the device to the user. Existing in-service machines were migrated to Intune management during scheduled maintenance windows. Conditional Access policies were configured to require MFA for cloud resource access, block legacy authentication protocols, and support a cleaner Microsoft 365 security baseline. Windows Update rings were established in Intune with a staged rollout: a pilot group deferring quality updates by seven days for validation, followed by broad deployment with a thirty-day deferral window. Once all devices were confirmed enrolled, compliant, and operating under cloud-managed policy, the on-premises domain controller was decommissioned.
Measurable result
What changed after launch
The on-premises domain controller was decommissioned at project close with no remaining on-premises identity dependency. All devices are enrolled in Intune with enforced compliance policies. Windows Autopilot handles zero-touch provisioning for any new or replacement hardware going forward. Remote staff access Microsoft 365 and company resources directly through Entra ID without requiring VPN or office connectivity. Staged Update Rings are in place to validate patches before broad rollout.
- On-premises domain controller decommissioned at project close
- All devices enrolled in Intune with enforced compliance policies
- Windows Autopilot live for zero-touch provisioning on new hardware
- Conditional Access enforcing MFA and blocking legacy authentication
- Staged Windows Update rings configured to validate patches before broad rollout
