From VMware to OpenShift—Without the Risk

For years, VMware has been a backbone of enterprise infrastructure around the globe. But rising costs, licensing changes, and the push toward cloud-native architectures are forcing organizations to rethink their strategy.

Red Hat OpenShift has emerged as a leading destination for organizations looking to modernize their environment as they depart from VMware. But here’s the problem:

Migrating from VMware to OpenShift/Kubernetes isn’t just a platform change, it’s a complete operational shift.

• Virtual Machines (VMs) → containers
• Static infrastructure → dynamic orchestration
• VM-level HA → database-level resilience

For database teams and infrastructure architects, this introduces real risk:

• Downtime during migration
• Complex re-platforming
• Loss of familiar HA models

The Missing Link Between VMware and OpenShift

Most migration strategies force you to choose:

• Lift-and-shift (low risk, low modernization)
• Full refactor (high reward, high risk)

DxEnterprise is a smart high availability clustering platform that works across VMs, containers, and cloud infrastructure—ultimately introducing a third migration strategy:

Controlled, low-risk modernization & refactoring with continuous availability.

Why DxEnterprise Is Different from Other Solutions

Legacy clustering technologies such as Windows Server Failover Clustering (WSFC) and Pacemaker were designed for static, tightly coupled environments.

They are:

• Bound to a single operating system (Windows or Linux)
• Dependent on low-latency, local networks
• Difficult (or impossible) to extend across:
  • Disparate cloud environments
  • Regions
  • Kubernetes/OpenShift

DxEnterprise fundamentally redefines database high availability by providing:

1. Simplified Cross-Platform Clustering (VM → Container → Cloud)
Unlike traditional HA tools that are tied to specific platforms and leave you vulnerable to vendor lock-in, DxEnterprise enables mix-and-match clusters across infrastructure and platforms.

You retain full control to customize your architecture to your exact specifications and manage all your SQL Server the same way whether it’s deployed on:

• Windows
• Linux
• OpenShift or Kubernetes

👉 In the case of a VMware to OpenShift migration, you can run a single cluster that spans your VMware virtual machines and OpenShift—eliminating the need for risky, extended-downtime cutovers.

2. Database-Level Protection
VMware HA protects at the virtual machine level. Kubernetes provides failover automation at the pod level. Neither can be considered an adequate solution when it comes to providing business-critical SQL Server workloads with the uptime and resilience they need.

DxEnterprise provides much more granular protection—ensuring high availability at the database level through seamless integration with SQL Server Availability Groups.

👉 In fact, DxEnterprise is the only solution that provides fully automated failover for SQL Server Availability Groups in Kubernetes & OpenShift.

3. Purpose-Built Technology for Stateful Databases Like SQL Server
DxEnterprise is built specifically to provide high availability for stateful, mission-critical workloads whether they’re deployed natively, or in containers. Features include:

• Database-level health monitoring
• Intelligent failover decisions
• Automatic cross-platform failover
• Consistent HA management across Windows, Linux, and containers

👉 This is critical for DBAs who can’t tolerate data loss or inconsistent failover.

4. Zero Trust Networking Without VPN Complexity
Moving from VMware often introduces networking challenges:

• New IP models
• Cross-cluster communication
• Firewall manipulations & other security issues

DxEnterprise comes with built-in software-defined perimeter technology that enables organizations to securely connect from anywhere, to anywhere with app-level ZTNA tunnels.

• No VPN required
• No open ports or data path intrusions
• Easy cross-region and cross-cloud connectivity

👉 This simplifies hybrid migrations immensely while improving overall security posture.

What a Migration Looks Like with DxEnterprise

Once you’ve stood up your new OpenShift cluster that you’ll be migrating some workloads to, a DxEnterprise-driven migrations goes as follows:

Step 1: Extend Your Cluster

Create a SQL Server Availability Group cluster that spans your existing VMware VMs and your new OpenShift node(s).

👉 DxEnterprise’s ability to simplify your cross-platform migration to containers really shines in this step thanks to its built-in SQL Server Operator for Kubernetes & OpenShift, DxOperator.

You simply define your desired state and configuration details for your new Availability Group (# of replicas, availability mode, etc.) using a custom resource YAML. Then DxOperator takes care of the rest—automating the deployment of your Availability Group and provisioning any Kubernetes resources that are needed.

Step 2: Synchronize Data

Use native Availability Group database replication. No third-party replication needed.

Step 3: Test Failover

Validate application movement between environments.

Step 4: Perform Live Migration

Trigger controlled failover from VMware → OpenShift.

👉 Throughout the full duration of this process, all your workloads remain protected by uncompromised high availability and fully automatic failover, whether they are deployed in VMs or containers.

Step 5: Optimize & Modernize

Refactor at your own pace, not in one giant, exposed migration push.

👉 Least possible disruption. No guesswork. No rushed modernization.​

The Bottom Line

Traditional clustering tools were built to protect within infrastructure/platform constraints.

DxEnterprise is built to mobilize database applications across infrastructure and keep them protected anywhere.

That’s the key differentiator, and the reason it enables:

• Low-risk VMware exits
• Incremental modernization
• True hybrid and multi-cloud high availability for instances and containers​

Ready to Leave VMware Without the Risk?

If you’re evaluating OpenShift but concerned about:

• Downtime
• Database complexity
• Migration risk

DxEnterprise is the missing piece that allows you to migrate from VMware to OpenShift with nearest-to-zero downtime, full control, and WITHOUT rebuilding your whole environment.
