VMware Migration After Broadcom — Proxmox, Hyper-V or Cloud?

After Broadcom acquired VMware, the virtualization world got nervous. The end of perpetual licenses, sales in subscription bundles, higher entry thresholds — for many companies the renewal now costs several times more than a year earlier, for the same environment. The question "should we leave VMware" turned into "where to, and how".

There's no single right answer. There are a few directions, and the choice depends on what you run, how you work and what you actually pay. Below are the four most common migration targets and when each makes sense.

TL;DR

• Proxmox VE — the most common on-premise successor; cheap, open, with optional vendor support
• Hyper-V — the natural pick when the company runs on Microsoft and Windows Server
• oVirt / OLVM — an open platform for larger environments, close to vSphere's logic
• Cloud (Azure, AWS) — when you want off your own hardware, not just a different hypervisor
• Do the math first — migration makes sense when it pays back in reasonable time, not "on principle"

Start with the math, not with the platform

The most common mistake is choosing a new platform before anyone has worked out what staying actually costs. Before we start migrating, we line up three numbers: the VMware renewal cost, the one-off migration cost, and the cost of running an alternative over several years. Only with that picture do you know whether the game is worth the candle — and how fast it pays back.

Sometimes the conclusion is that with a freshly paid contract and deep integration with VMware tooling, migration simply doesn't add up. We say so plainly — we don't make money talking you into a project that makes no sense.

Proxmox VE — the default on-premise successor

This is the direction most companies leaving VMware pick today. Proxmox is built on proven, open components: KVM for virtualization, LXC for containers, Ceph or ZFS for storage. It offers clustering, live machine migration, built-in backup and a readable interface.

Who it's for: on-premise environments that want to stay on-premise, cut licensing cost and aren't afraid of a platform outside the big three. With a vendor support subscription Proxmox comfortably runs production — provided the cluster, storage and backup are well designed from the start.

Hyper-V — when you live in the Microsoft world

If the company runs on Windows Server, Active Directory and Microsoft licensing, Hyper-V is often the cheapest route: the hypervisor is part of the OS, integrates with Failover Clustering and familiar admin tools. Licensing is handled under CSP, and the team usually already knows the ecosystem.

Who it's for: organizations with a strong Microsoft foundation, where adding another foreign platform would be a step backwards.

oVirt and cloud — two poles

oVirt (and the commercial OLVM) is an open platform close to vSphere's logic — sensible for larger environments that want to stay on-premise but need something more "enterprise" than Proxmox.

Cloud (Azure, AWS) is a different decision: you don't change the hypervisor, you get off your own hardware. It makes sense when workloads are variable, you're facing a server-room refresh, or you're heading toward cloud services anyway. Often a hybrid model wins — steady workloads on-premise, elastic ones in the cloud.

How to migrate without losing your nerve

Whatever the target, the order is similar: audit the vSphere environment, design the target, migrate machines in phases (less critical first, production last) and take a fresh backup before each move. We described centralized backup and disaster recovery across a multi-hypervisor environment in a separate case study on Veeam in multi-hypervisor.
