vSphere 8 support ends in 2027. Plan your VMware move now

If your servers run on VMware, you have a deadline that is less than a year away. Broadcom has set October 11, 2027 as the end of support for vSphere 8 and the products around it. Whatever you decide to do next, whether that is upgrading, renewing on a new subscription or moving some workloads elsewhere, the work takes months. The businesses that start now will have choices. The ones that wait will have a renewal quote and a short runway.

What is changing and when

Broadcom's end-of-service notice lists October 11, 2027 for ESXi and vCenter Server 8.x, vSAN 8.x, NSX 4.x, VMware Cloud Foundation 5.2.x and several Aria 8.18 products. After that date, Broadcom says it will not provide technical support or new patches for those versions. Its recommended path is VMware Cloud Foundation 9 or vSphere Foundation 9.

For a mid-size business, that means a hypervisor without security patches by late 2027 unless you act. Running unpatched infrastructure underneath your business applications is a risk most insurers, auditors and boards will not accept for long.

Why the cost question comes first

The upgrade is the easy part to describe. The cost is harder. Broadcom now sells VMware as subscriptions licensed per physical core. Its core-counting guidance sets a minimum of 16 cores for every physical processor, even when the processor has fewer. A host with two 8-core CPUs is licensed as 32 cores. If your servers are older or lightly loaded, the core count you pay for may be well above what you use.

Many customers have already felt this. In its Magic Quadrant for Server Virtualization Platforms, Gartner says clients have reported that the move to per-core subscriptions "resulted in significant cost increases," along with minimal flexibility in negotiations, according to reporting by The Register on September 22. In a separate report, Gartner predicts that by 2029, 55% of enterprises will start proofs of concept for alternatives to their VMware-based deployments, up from 25% in 2026.

A survey published October 7 points the same way. It was conducted by Unisphere Research and commissioned by Rimini Street, which sells third-party VMware support, so read it as vendor research. Of 269 VMware users surveyed, nine in ten said higher licensing costs were prompting them to consider alternatives, and 60% were considering using more than one hypervisor. The same respondents named operational complexity (40%) and team skills (37%) as barriers to changing.

Staying with VMware is still a reasonable choice for many businesses. The point is to make it a choice, with the numbers in front of you.

Know what you run before you get a quote

Start with an inventory. For every host, capture:

• The VMware version, license type and contract end date.
• The physical CPUs and cores, and how many are counted under the 16-core minimum.
• How busy each host is, so you can see whether consolidation would reduce cores.
• Which applications run on it, who owns them and how critical they are.
• Hardware age and warranty status, since a VMware decision is often also a hardware decision.

This inventory is what turns a quote you have to accept into a quote you can test.

Compare the realistic options side by side

Most businesses end up choosing from a short list. Renew and upgrade to VCF 9 or VVF 9, ideally after consolidating hosts to reduce licensed cores. Move to another on-premises hypervisor. Move some or all workloads to a public cloud, a private hosted cloud or a managed hosting provider that carries the licensing for you. Or combine these, keeping critical systems where they are and moving the rest.

Compare them on the same basis. Include licenses, hardware, migration labor, staff training, backup and recovery tooling, and the cost of running two platforms during the transition. A cheaper license can be offset by a long migration, and a familiar platform can cost more than it is worth. Ask each provider for a written migration plan, not just a price.

Work backward from October 2027

A migration of any size needs testing, application owner sign-off and a rollback plan. Count back from the deadline. Allow time for a proof of concept, procurement and contract review, then a phased move. For many mid-size businesses that means making the platform decision in the first half of 2027. Check your current VMware contract end date too. If it falls before October 2027, your renewal is the first decision point, and the term you sign will shape your options.

Ask every provider these questions in writing. What exactly is included at this price? What is the price-increase cap on renewal? What support and patching do we get, and until when? What will migration cost, and who carries the risk if it runs long?

How StrategIQ IT can help

Before founding StrategIQ IT, Brian spent much of his career as the enterprise customer accountable for infrastructure and renewals, then built a practice on the partner side around what he had wanted as a buyer. We can help you build the inventory, model the options on a like-for-like basis and plan the timeline back from October 2027. We are vendor-agnostic by design. Our partnerships span more than 200 providers across cloud, colocation, hosting and managed services, and in most cases StrategIQ is paid by whichever provider you choose, so we have no reason to steer you to one platform. Working through us does not raise your price, and our market knowledge often helps negotiate better pricing and terms. Our infrastructure checklist is a practical place to start. If infrastructure decisions keep landing on nobody's desk, our fractional CIO / CTO service provides ongoing senior technology leadership to own the roadmap, renewals and provider relationships. Scope, fees and how StrategIQ is paid are explained before you proceed. The first 20-minute conversation is free.
