We Knew This Was Coming: VMware Loyalty Turns Into a Proxmox Exit

The slow goodbye that suddenly feels urgent

There's something oddly emotional about ripping out infrastructure that's been around since the late '90s. One engineer described starting a migration away from VMware as "bringing some sadness," especially for a client that's been all-in since 1998. That kind of software carries muscle memory, habits, and years of trust. Sentiment doesn't survive a pricing shock, though. When licenses expire in 2026 and renewal quotes spike, nostalgia gets replaced by spreadsheets, and those spreadsheets don't lie.

The shift wasn't impulsive. It came after proof-of-concept testing, cost comparisons, and a narrowing of options down to two finalists, Hyper-V and Proxmox. In the end Proxmox won, with Ceph in the mix. That decision says a lot about where enterprises are looking now: less at brand legacy, and more at survival and flexibility.

"We all knew this would happen"

Not everyone watching this unfold is surprised. In fact, a lot of voices are almost sarcastic about it. One comment sums it up bluntly: "If only they had given us some indication they were going to extort customers sooner." Another adds, "We all knew this would happen." There's a sense that the writing has been on the wall for a while, especially after major corporate shifts and acquisitions.

The mood is closer to resignation than outrage. For years, VMware was the safe bet and the default choice. When pricing changes feel less like adjustments and more like ultimatums, even the most loyal customers start exploring exits. Some see this as a predictable consequence of consolidation in the enterprise software world, and others see it as a misstep that could permanently damage trust. Either way, the tone has shifted, and VMware is no longer untouchable.

The migration mountain nobody wants to climb

Deciding to leave is one thing, and actually leaving is something else entirely. One commenter pointed out the obvious: migrating thousands of virtual machines in just a few months sounds borderline reckless. "Isn't that cutting it too close?" they asked. It's a fair concern. These aren't small environments. We're talking about massive deployments where even minor missteps can ripple into downtime, lost data, or worse.

Still, a counterpoint keeps popping up: migrations are painful, but they're also opportunities. One engineer framed it as a chance to "reduce technical debt." Another noted they had already dropped hundreds of unnecessary systems during the process. When you're forced to move, you finally clean house.

None of that makes it easy. This is the kind of project that keeps teams up at night, because tight timelines, massive scale, and unfamiliar platforms add up to a lot of stress.

Proxmox: smart escape or risky bet?

The choice of Proxmox has sparked its own debate. Some see it as a bold, cost-effective move, and others are far less convinced. One particularly critical voice warned that relying on Proxmox at scale could turn into a "day 2 nightmare," especially if enterprise-grade support falls short. There's concern about what happens when things break, and they always do.

On the other hand, there are examples of large organizations successfully moving away from VMware, even at massive scale. Some point to banks handling tens of thousands of VMs as proof that alternatives can work. The truth probably sits somewhere in the middle. Proxmox isn't a drop-in replacement for VMware's ecosystem, and it doesn't need to be. It just needs to be good enough and significantly cheaper.

A hybrid reality is creeping in too. Certain workloads still require Hyper-V due to vendor support constraints, so the future looks like a patchwork of platforms instead of a clean break. That's not ideal, but it's increasingly common.

The bigger shift: from loyalty to leverage

One company switching platforms is part of a broader change in how enterprises think about infrastructure. Loyalty used to be a given. You picked a vendor, invested deeply, and stuck with them for decades. Now everything is negotiable.

Rising costs are forcing organizations to rethink assumptions. Open-source and alternative platforms have become serious contenders instead of fringe options, and once a company proves it can migrate away from a giant like VMware, the conversation changes entirely.

Power is shifting a little, too. Vendors used to hold most of the leverage, and now customers are showing they're willing to walk. Migrations are still hard and risky, but the threat of leaving is real, and sometimes that's enough to reshape the market.

In the end, this story is less about saying goodbye to VMware than about what happens when the default choice stops making sense. Once that happens, there's no going back.
