Active Directory Functional Level Upgrade for K-12 Infrastructure Modernization

Windows Server 2022 Domain Services Modernization and VMware vSphere 8 Upgrade

Strengthening Identity Services and Virtual Infrastructure

This Maryland public school district launched a comprehensive infrastructure modernization initiative to improve security, streamline administration, and ensure long-term supportability across its identity and virtualization environments. With Active Directory domain controllers approaching end-of-support milestones and VMware infrastructure running older software versions, the district needed a strategic approach that would reduce risk while improving operational efficiency.

To achieve these objectives, Data Networks executed a two-phase modernization project centered on an Active Directory functional level upgrade, domain controller consolidation, and a full VMware infrastructure refresh. The project modernized critical identity services, optimized licensing investments, reduced administrative complexity, and upgraded the district’s production and disaster recovery VxRail environments to VMware vSphere 8.

Addressing Legacy Identity and Infrastructure Challenges

The district’s Active Directory environment was operating at a Windows Server 2012 R2 domain functional level and relied on ten domain controllers distributed across multiple locations. As support deadlines approached, the organization faced growing security, compliance, and lifecycle concerns.

In addition, the Active Directory environment contained a large number of Group Policy Objects that had accumulated over time, increasing management complexity and administrative overhead.

The district’s virtual infrastructure also required modernization. Two Dell EMC VxRail clusters supporting production and disaster recovery operations were running older versions of VMware vCenter, VMware vSphere, VMware vSAN, VxRail Manager, RecoverPoint for VMs, and VMware Tools. Remaining on unsupported software versions introduced operational risk and limited access to new capabilities, security enhancements, and vendor support.

The district required a carefully coordinated modernization strategy that would improve security, maintain availability, and minimize disruption to instructional and administrative services.

Performing the Active Directory Functional Level Upgrade

The first phase of the engagement focused on modernizing the district’s Active Directory environment and preparing it for future growth.

Data Networks conducted a comprehensive assessment of the existing identity infrastructure and implemented several improvements, including:

• Upgrading Active Directory domain controllers to Windows Server 2022
• Performing an Active Directory functional level upgrade
• Reducing the number of domain controllers from ten (10) to five (5)
• Distributing domain controllers across production and disaster recovery data centers
• Reviewing Active Directory organizational units and architecture
• Consolidating redundant Group Policy Objects
• Removing obsolete policies and configurations
• Improving administrative efficiency and manageability
• Delivering documentation and knowledge transfer for district IT staff

The upgraded architecture provided a more streamlined and supportable identity platform while improving resiliency across both data center locations.

Modernizing VMware VxRail and Disaster Recovery Platforms

Following completion of the Active Directory modernization, Data Networks proceeded with a comprehensive virtualization platform upgrade across the district’s two Dell EMC VxRail environments.

The project included:

• Upgrading Dell EMC RecoverPoint for VMs
• Upgrading Dell EMC VxRail Manager
• Upgrading VMware vCenter
• Upgrading VMware vSphere Enterprise Plus to version 8
• Upgrading VMware vSAN Advanced to version 8
• Updating Dell EMC VxRail firmware, drivers, BIOS, and supporting components
• Upgrading VMware Tools across approximately 75 virtual machines
• Validating replication and disaster recovery functionality
• Performing post-upgrade testing and system validation

All upgrades were executed through carefully planned maintenance windows designed to minimize service interruptions and maintain availability for district users.

Establishing a More Secure and Sustainable Technology Foundation

Upon completion, the district gained a modernized identity and virtualization platform aligned with current vendor support standards and cybersecurity best practices.

The Active Directory functional level upgrade enabled the district to modernize its domain services architecture, improve security, and reduce management complexity. Consolidating domain controllers and optimizing Group Policy administration simplified day-to-day operations while maintaining high availability across multiple locations.

At the same time, the VMware infrastructure modernization restored supportability and positioned the district to leverage the latest capabilities available within VMware vSphere 8, VMware vSAN 8, Dell EMC VxRail, and RecoverPoint.

Together, these improvements created a resilient, scalable, and operationally efficient infrastructure platform capable of supporting the district’s instructional, administrative, and disaster recovery requirements for years to come.
