Stay Ahead of IBM Sub-Capacity Compliance: Introducing IBM SubCapacity Technology Eligibility

We’re excited to announce a major enhancement in the ITAM June 2026 release: full visibility into IBM sub-capacity licenses and the inventory devices running end-of-support (EOS) operating systems and virtualization technologies, enabling organisations to reduce compliance risk, maintain sub-capacity eligibility, and proactively plan upgrades of technologies that are EOS or announced to be EOS in the future for IBM sub-capacity licensing.

With this release, you can quickly pinpoint sub-capacity licenses and related inventory devices running operating systems or virtualization technologies that have already reached EOS or are scheduled to within the next 180 days so you can act before compliance becomes a concern.

IBM regularly refreshes the list of operating systems and virtualization technologies ineligible for sub-capacity licensing, removing versions that have reached end of standard support (EOS) from their vendors. Once removed, these technologies are no longer supported by the IBM License Metric Tool (ILMT). Customers typically have a 180-day window to migrate to supported versions, although in some cases the effective removal date may extend further with compliance still required by the specified deadline.

To help customers stay informed and plan upgrades proactively, IT Asset Management June 2026 release leverages IBM EOS lifecycle data to automatically flag inventory devices linked to IBM sub-capacity licenses that are running operating systems or virtualization technologies which have reached or are approaching EOS. For more details, see the online documentation.

ITAM Continued Tracking with Backward Compatibility

IT Asset Management (including FNMS) continues to support inventory agent versions that work with EOS operating systems and virtualization technologies. That means uninterrupted resource usage inventory data collection and ingestion for accurate sub-capacity license calculations even while you’re transitioning to supported platforms.

What’s new in this release:

Enhanced Compliance Visibility

Gain clearer visibility into devices running EOS operating systems or virtualization technologies tied to IBM sub-capacity licenses. A new license alert now appears on applicable sub-capacity license types whenever related inventory devices are running EOS technologies.

The new alert “This license has one or more devices running technology that IBM has declared ineligible for subcapacity licensing” appears for each affected sub-capacity license on the “All Licenses” page and within the license properties “Possible Issues” section, making it easy to spot licenses that may need EOS technology upgrades.

The License Consumption grid now includes a new filter showing the number of inventory devices running EOS operating systems or virtualization technologies giving you faster insight into where action is needed.

 IBM Sub-Capacity Peak and Current Consumption Reports Extended

Quickly identify non-compliant or at-risk environments where EOS technologies are in use. This makes it easier to plan upgrades proactively and have informed conversations with IBM about migration and upgrade timelines.

Note: The example screenshot below shows a PUV license consumption report, but the same applies to all IBM sub-capacity license types reports.

Dedicated EOS Visibility Report

The new IBM Ineligible Technology report delivers a single, consolidated view of devices running technologies that are already ineligible (where the removal date has passed) alongside those approaching a future removal date so you can stay ahead of operating system and virtualization technology upgrades.

Important Note: The IBM ineligible technology indicator is a risk indicator only. It does not automatically change how license consumption is calculated. You should review flagged devices and take appropriate action as required to remain compliant with IBM sub-capacity licensing requirements. Flexera recommends engaging with IBM to agree on upgrade timelines for EOS technologies, to maintain sub-capacity eligibility while transitioning from EOS platforms to supported versions.

This enhancement is available now in Flexera One ITAM with the June 2026 release, and will reach on-premises customers in FNMS On-Premises 2026 R1. Explore the new capabilities and strengthen your IBM sub-capacity compliance posture by proactively planning upgrades of EOS operating system and virtualization technologies.
