IBM has been quietly ending a licensing model that IBM i customers relied on for decades, and the shift is now essentially complete for anyone buying current-generation hardware. IBM began transitioning the IBM i platform to subscription licensing back in 2022, and for customers purchasing specific Power10-based P05 and P10 software tier machines, adoption of subscription-based licensing became mandatory starting in May 2024, with that requirement now extending naturally into the current IBM Power11 generation.
Why This Matters More on Power11 Than It Did on Power10
The subscription requirement was easier to overlook when it applied narrowly to specific Power10 tier machines, since many organisations simply continued running existing perpetually licensed hardware without needing to confront the new model directly. IBM’s own portfolio simplification documentation confirms that products previously requiring separate, sometimes costly licences, are now included as part of the base IBM i offering at no additional charge, removing licence checks for a defined set of tools that customers previously had to purchase and manage individually, a genuine simplification that arrives alongside, rather than instead of, the new subscription requirement.
That option narrows considerably with each new hardware generation. An organisation whose next planned refresh moves to Power11 is stepping directly into a licensing environment where the subscription model is the default and, for many tiers, the only path available, making this a genuine budgeting decision rather than an abstract policy change that could be deferred indefinitely.
What Actually Changed Beyond the Payment Structure
It is worth understanding that this shift is not simply the same software repriced onto a recurring bill. IBM has simultaneously simplified the broader IBM i portfolio alongside the licensing model change, folding previously separate, individually chargeable products directly into the base IBM i offering at no additional charge. Products that customers previously had to licence and pay for separately are now included as part of the core platform, which means an organisation evaluating the true cost impact of the subscription shift needs to weigh the new recurring fee against genuine functionality gains, not simply compare old and new prices for an identical feature set.
That bundling detail matters for building an accurate total cost comparison. An organisation that budgets purely for the new subscription fee, without also accounting for the separate licences it no longer needs to purchase because that functionality is now included, is likely to overstate how much the shift has actually increased its total IBM i cost.
The Transferability Question Worth Raising Directly
Subscription licensing changes the assumptions many organisations have historically built around IBM i asset management, particularly around hardware transfers, resale, and multi-entity structures. Perpetual licences carried genuine, if sometimes restricted, transfer rights that organisations built into their broader hardware refresh and divestiture planning over the years. A subscription model tied to an active, ongoing commercial relationship behaves differently, and organisations with any planned merger, acquisition, divestiture, or simple hardware resale on their roadmap should confirm directly with IBM exactly how subscription entitlements transfer, or fail to transfer, under the new model before assuming continuity with how perpetual licences worked previously.
Building an Accurate Multi-Year Comparison
The practical response for any organisation planning a Power11 refresh is building a genuine multi-year total cost comparison between continuing on existing perpetually licensed hardware for as long as practically possible, versus moving to the new subscription model now. That comparison needs to include the value of the newly bundled, previously separately licensed products, the genuine operational and security benefits of running current-generation hardware, and an honest assessment of how much longer the existing perpetual estate can realistically be supported before a refresh becomes unavoidable regardless of the licensing model attached to it.
Why Waiting Does Not Avoid This Decision
It is tempting to treat this shift as something to defer by continuing to run older, perpetually licensed IBM i hardware for as long as possible, but that strategy has a genuine expiry date attached to it. Hardware support lifecycles, security patch availability, and IBM’s own broader product roadmap all continue moving forward regardless of an individual organisation’s licensing preference, and an organisation that defers this decision indefinitely eventually faces the same subscription requirement anyway, simply on a less favourable timeline forced by hardware end-of-life rather than chosen deliberately as part of a planned refresh cycle.
Conclusion
IBM’s shift of the IBM i platform to subscription-only licensing on current hardware generations closes a multi-decade chapter of perpetual licensing on this platform, and the change now applies broadly enough, extending naturally into Power11, that most organisations planning a near-term hardware refresh will encounter it directly rather than being able to defer the decision further.
Building an accurate multi-year cost comparison that properly accounts for newly bundled functionality, and confirming transferability terms directly before any planned merger, divestiture, or hardware resale, are the practical steps that turn this transition into a properly evaluated decision rather than a surprise encountered at the next hardware refresh.
