A Macau Public Service Organization

A public service organization in Macau, China, had long relied on the Microsoft Hyper-V virtualization platform to support key business modules, including financial accounting, retail operations, and office collaboration. As the organization advanced its digital transformation and faced the upcoming release of Windows Server 2025, it urgently needed to address critical pain points in its existing platform, such as a lack of high availability, limited scalability, and inefficient operations. At the same time, the organization aimed to reuse its existing hardware assets to lower the Total Cost of Ownership (TCO).

By deploying the ZStack ZSphere virtualization platform to completely replace Hyper-V, the client achieved a seamless transition for its core services. The upgrade resulted in a significant boost in operational efficiency, a notable reduction in hardware and software TCO, and greatly enhanced business reliability. This successful migration from a closed architecture to an open cloud platform has laid a solid IT foundation for future business innovation.

The Challenge: A Legacy Platform Hindering Digital Transformation

As the core IT backbone for multiple business units, the organization’s Hyper-V platform gradually fell behind the pace of its development. Key challenges included:

1.Lack of High Availability: The platform lacked a comprehensive centralized management and high-availability mechanism. Any failure could easily lead to service interruptions, making it difficult to guarantee the continuous operation of critical business applications.

2.Limited Scalability and Elasticity: Its features were relatively basic, preventing large-scale, multi-node management. The lack of elastic resource scheduling made it difficult to respond quickly to peak business demands or deploy new services.

3.Inefficient Operations and Maintenance: Without a unified web-based management interface, daily maintenance and system expansion were cumbersome and complex. This not only consumed significant manpower but also resulted in slow response times, severely impacting business efficiency.

With the launch of Windows Server 2025 on the horizon, the organization planned to upgrade its IT architecture. However, its existing servers and storage devices were becoming unstable. A traditional “rip-and-replace” approach would have led to wasted assets and a sharp increase in procurement and maintenance costs. The core challenge became clear: how to achieve a significant platform upgrade and smooth business migration while reusing existing hardware to lower TCO.

After multiple rounds of solution evaluation and technical testing, the ZStack ZSphere virtualization platform was chosen for its outstanding advantages in heterogeneous platform replacement, hardware reuse compatibility, and seamless migration.

The Solution: A “Reuse, Migrate, Operate” Approach for a Seamless Transition

Tailored to the client’s unique IT environment and business needs, ZStack delivered an integrated solution focused on compatibility for hardware reuse, smooth migration, and centralized operations. With ZStack ZSphere at its core, the transition from Hyper-V was seamless and worry-free.

1. Hardware Reuse: Protecting Existing Investments

ZStack ZSphere is compatible with a wide range of server brands, models, and generations. The client was able to fully integrate and efficiently utilize its existing servers and storage devices without needing to purchase new hardware. This approach avoided wasted assets and unlocked the full value of existing resources through cloud-based orchestration, aligning perfectly with the organization’s goals for cost control and sustainability.

2. Phased Migration: Ensuring Business Continuity

To ensure zero disruption to core business operations, ZStack implemented its comprehensive “Five-Step Migration Methodology,” covering the entire lifecycle from initial assessment to post-migration management. This made the entire process controllable and traceable.

· Pre-Migration Planning: ZStack’s technical team conducted a thorough assessment of the client’s Hyper-V cluster configuration, storage layout, and virtual machine OS versions (covering the full range from Windows Server 2003 to 2025). They mapped out business criticality and dependencies to create a phased migration strategy, validated through multiple simulations.

· Stable In-Migration Execution: Leveraging the incremental synchronization capabilities of ZStack ZMigrate, any data generated during the migration process was quickly compared and synced. With on-site and remote engineering support, the team followed a standardized “Incremental Sync → Final Cutover → Start-up Verification” process to ensure zero data loss.

· Post-Migration Operations: All virtual machines were centrally managed under the ZStack ZSphere control plane. A unified, visual management interface provided centralized monitoring of resources, performance, and alerts. Automated O&M features like batch upgrades, scripted operations, and intelligent alerting dramatically simplified the management workflow.

3. Core Capability Upgrade: Meeting Modern Business Demands

The ZStack ZSphere platform empowered the client’s business upgrade with powerful new features:

· Comprehensive Cross-Version Compatibility: Full support for Windows Server versions from 2003 to 2025, allowing existing business systems to run smoothly without modification.

· Robust High-Availability Architecture: Features like automatic VM recovery, dual management node HA, and dynamic resource allocation created a multi-layered high-availability framework, eliminating single points of failure.

· Intelligent Scheduling for Enhanced Efficiency: The web-based visual operations platform and intelligent resource scheduling enabled flexible allocation and efficient use of resources. The platform also supports live migration and elastic scaling to effortlessly handle business growth.

Customer Outcomes: A Leap in Value and Innovation

By deploying ZStack ZSphere, the Macau-based organization successfully replaced Hyper-V and upgraded its IT architecture, achieving breakthroughs in business performance, cost savings, and efficiency.

· Significant Improvement in O&M Efficiency (50% Increase): The unified web interface and automated O&M functions replaced tedious manual operations. Capabilities like batch upgrades, intelligent alerts, and centralized monitoring freed the IT team from repetitive tasks, allowing them to focus on core business support and innovation.

· Effective Reduction in Total Cost of Ownership (TCO) (40% Decrease): By fully reusing existing hardware, the organization avoided massive capital expenditures. Simplified O&M also reduced labor costs. The savings were redirected to fuel business expansion and innovation.

· Enhanced Architectural Flexibility: The platform’s support for large-scale, multi-node management and elastic resource scheduling enables rapid responses to new service deployments and peak business demands. Moving from a closed architecture to an open cloud platform has provided a flexible and scalable IT foundation for the company’s ongoing digital transformation.
