How to Migrate from VMware to Proxmox VE with Stackscale: An Efficient and Secure Alternative

The recent acquisition of VMware by Broadcom has led to significant changes in the virtualization market. The shift to a subscription-based licensing model, the restructuring of the partner ecosystem, and cost variations have prompted many organizations to rethink their IT strategy.

In this new landscape, Proxmox VE emerges as a robust, flexible, and growing open source solution. At Stackscale, we continue to offer VMware-based infrastructure for customers who need it. However, we also provide a comprehensive migration service from VMware or other hypervisors for those looking to explore new alternatives—without compromising the stability or security of their infrastructure.

A Migration Tailored to Each Organization

No two IT environments are the same. That’s why our team customizes every migration project to meet the specific characteristics and objectives of each client. This personalized approach allows us to offer a secure, planned transition with no service interruptions—regardless of the number of virtual machines or the size of the infrastructure.

We work in close collaboration with technical teams to:

• Assess the current environment and define a realistic migration plan.
• Automate critical tasks to improve efficiency and reduce human error.
• Validate each workload’s functionality before final cutover.
• Provide guidance before, during, and after the migration.

As part of this process, we also help improve the target infrastructure—adding capabilities such as enhanced availability and resilience, disaster recovery and business continuity planning, and even deploying dual geo-replicated zones with synchronous storage to achieve RTO=0 and RPO=0.

Our Step-by-Step Migration Approach

At Stackscale, we apply a clear, structured methodology—refined through real-world experience—to ensure migration success. The key stages include:

1. Pre-Migration Assessment

We analyze the current VMware environment, identify technical and functional dependencies, collect usage and performance metrics, and detect potential risks. This information is used to design a migration plan aligned with business goals.

2. Target Environment Setup

We deploy and configure the Proxmox VE environment, including networks, storage, security policies, and backups. A pilot migration is performed using selected virtual machines to validate the process and fine-tune the configuration.

3. Migration Execution

We convert virtual machines using automated tools, verify data integrity, and perform phased transitions—ensuring production systems remain untouched until the right moment.

4. Testing and Validation

We test application behavior, performance, connectivity, and workflow integrity in the new environment. Rollback procedures are also defined and tested, just in case a reversal becomes necessary.

5. Optimization and Tuning

Once in production, we optimize the configuration of resources (CPU, RAM, storage, network, and even GPU). We also activate features such as high availability, monitoring, and task automation.

6. Support and Knowledge Transfer

Post-migration, we provide active technical support, documentation, and—if needed—training for internal teams. Our goal is to ensure that each client can operate their new infrastructure confidently and independently.

Benefits of Migrating to Proxmox VE with Stackscale

Migration is not only an opportunity to change platforms—it’s a chance to enhance efficiency, control, and infrastructure flexibility. Key advantages include:

• Zero-impact transition: fully planned and tested before production cutover.
• Advanced automation: reduces manual errors and conversion times.
• Data protection: with backups, restore points, and granular recovery options.
• Cost reduction: through predictable licensing and more efficient resource use.
• Infrastructure and HA improvements: including geo-replication across two data centers, synchronous storage with RTO=0 and RPO=0, and updated disaster recovery strategies.
• Expert support: from initial assessment to full production operation.
• Regulatory compliance: with technical documentation for GDPR, ISO 27001, ENS, and other frameworks.

Why Choose Proxmox VE

Proxmox VE is an open source virtualization platform that combines the robustness of the KVM hypervisor with the agility of LXC containers. It simplifies the management of complex virtual environments without sacrificing control or scalability.

Its key features include:

• Centralized web-based management console.
• Multi-node clustering with high availability.
• Integrated backup and programmable snapshot systems.
• Software-defined storage support (ZFS, Ceph), and compatibility with our own network storage and synchronous storage solutions.
• Seamless integration with the Stackscale Network, which operates independently of the virtualization platform—allowing networks to be shared across both VMware and Proxmox environments.
• Active community and transparent subscription model.
