If like many businesses in 2026, you continue to run unsupported versions of VMware, you’re sitting on a time bomb that will cost much more than you think you are saving. Maybe you are holding off due to licensing changes or budget concerns, or maybe you just don’t have time for upgrades. Regardless of your reasons, this unsupported software can expose your business to security, operational, and compliance risks that far outweigh the cost of updating or switching to an alternative.
Why do businesses operate unsupported versions of VMware?
Many organizations continue to use older VMware environments simply because they think the systems are working fine and don’t see the need to upgrade.
However, as you may already know, recent changes to VMware's licensing model have led to a spike in companies foregoing the newest versions out of budget concerns or just spite. Instead of going along with yet another anti-consumer cash grab from the tech sector, many organizations chose to stick it out until they can deploy an alternative.
Are you running out-of-date VMware?
It’s important to check when your VMware products reach their end of life/service (EOL/EOS) to ensure you aren’t running an unsupported version without realizing it.
Warning signs that your environment may no longer be supported include:
- Your VMware version has reached its published support end date.
- You are no longer receiving security updates.
- VMware support is unavailable for your deployment.
- Your hardware or operating systems are no longer certified for your VMware version.
- New applications or security tools are no longer compatible.
Have your team or your IT services provider review the lifecycle information for your VMware products to determine if your virtualization platform remains supported. If your current version is no longer supported, it is important to plan and budget for an upgrade or migration to a newer version as soon as possible.
The risks of operating with unsupported VMware
Discovering your VMware products are out of date might not seem like an urgent issue, but the consequences of ignoring it can be severe.
Cyberattacks
The biggest risk of unsupported virtualization software is security. Once support ends for a software product, attackers actively analyze it for weaknesses because they know official security fixes are no longer forthcoming. If they find a vulnerability in that software, any company still running it becomes an easy target.
Continuing to operate with out-of-date IT, especially network infrastructure such as virtualization software, you’re leaving the back door open for ransomware, data breaches, and more.
Increased operational risk
If you’re operating old VMware and a host fails or an unexpected software bug appears, obtaining technical support may be difficult or impossible. The lack of official support means recovery times become significantly longer, driving up the cost of outages.
Compatibility problems
Modern operating systems, backup platforms, security solutions, and management tools may no longer work correctly with outdated virtualization software. These incompatible systems can lead to performance issues, errors, and downtime.
Compliance violations
If your organization is subject to regulatory requirements, unsupported infrastructure may create compliance concerns because many cybersecurity frameworks expect your critical systems to receive ongoing security updates.
Update or replace: How to keep virtualization current and secure
If your VMware environment is approaching end of support, now is the time to plan your next steps rather than waiting for an emergency.
Start with a complete assessment of your virtualization environment. Identify your VMware version, supported hardware, virtual workloads, backup systems, and application dependencies before making any changes.
From there, you can determine whether upgrading to a supported VMware release makes the most sense or whether migrating to another virtualization platform better aligns with your budget and long-term IT strategy.
If you decide to move away from VMware, several mature virtualization platforms are available in 2026, ready to capitalize on the wave of dissatisfied former VMware users. Which one is the right choice for your business depends on your workload requirements, budget, compliance obligations, and future growth plans.
