IBM i Licensing in the Cloud: Entitlement Transfer, Subscription, and BYOL

Can you bring your own IBM i license to the cloud?

Usually not in the way teams expect. On IBM Power Virtual Server the per-core rate already includes the IBM i license and software maintenance, and IBM's FAQ says you cannot use an existing purchased license for the OS (the movable-license option can credit entitlements under active SWMA at a reduced rate). With a managed hosting provider the logic reverses: your perpetual entitlements can transfer permanently to the provider's machine or to a virtual serial number, but the transfer is fee-based per core. New IBM i licenses are effectively subscription-only as of 2026, and third-party ISV keys tied to your old serial number are the cost item most migrations underestimate.

Practical decision support

Price the licensing disposition before the infrastructure

Use this guide to decide, entitlement by entitlement, whether licenses transfer, convert to subscription, get credited through IBM's movable-license option, or get repurchased inside the target platform's rate.

  • Pull serials, software tiers, and SWMA status for every machine from IBM Entitled Systems Support before comparing platforms.
  • Compare transfer fees, subscription conversion, and PowerVS bundled pricing per workload rather than assuming one answer fits all.
  • Inventory every third-party product and confirm key transfer terms in writing before setting a cutover date.

At a glance

Key takeaways

New IBM i licenses are effectively subscription-only

IBM withdrew new perpetual P05/P10 entitlements in spring 2024 and perpetual P20/P30 OS licenses effective January 1, 2026; IBM i on Power11 is subscription-only. Existing perpetual licenses remain valid on existing machines.

PowerVS includes the OS license, and blocks BYOL

The hourly per-core rate bundles IBM i, software maintenance, unlimited users, and most LPPs. IBM's FAQ rules out reusing an existing OS license; the movable-license (MOL) option is the partial exception.

Entitlement transfers are real money

Perpetual license transfers to a hosting provider's machine are fee-based per core. IT Jungle reported $8,954 to $26,482 per core after IBM's July 2025 increases, depending on transfer group.

ISV keys are the classic budget miss

Third-party keys tied to a serial number or processor tier usually need reissuing, and sometimes repricing, when the serial changes. Inventory every vendor early, including the small tools.

How IBM i Licensing Actually Works: Cores, Tiers, and Serial Numbers

IBM i is licensed per processor core, and every Power machine falls into a software tier (P05, P10, P20, or P30) that sets the price of the operating system and its licensed program products (LPPs). Machines in the P05 and P10 tiers carry both processor and user entitlements; P20 and higher tiers are priced on processor entitlements alone. Entitlements are recorded against a specific machine serial number in IBM’s Entitled Systems Support (ESS), and license keys are generated against that serial. Keys require at least one active per-processor IBM i license (perpetual, subscription, or temporary); ESS also offers self-serve 40-day interim keys to bridge a pending order or transfer.

That serial anchoring is why cloud licensing gets complicated: entitlements stay with the box, not the workload. IBM’s portability answer is the Virtual Serial Number (VSN), announced in January 2022 (announcement letter ENUS122-017). A VSN is its own serial number, so IBM i software can be ordered on, or transferred to, the VSN rather than the physical machine, letting a partition move between Power machines without stranding its licenses. Licensing is also the top cost lever in a Power cloud move; our breakdown of what drives IBM Power migration cost treats it as the first number to pin down.

The Subscription Shift: Where IBM i Licensing Stands in 2026

IBM began moving IBM i to subscription pricing in May 2022 at the P05 tier, initially on the 4-core Power S914 and then the S1014, per IT Jungle. In spring 2024, IBM withdrew the ability to buy new non-expiring (perpetual) IBM i entitlements for the P05 and P10 tiers. The exact date is reported inconsistently (IBM’s community notice says March 26, 2024; reseller Mainline cites May 7, 2024), but the direction was unambiguous.

The July 8, 2025 Power11 announcements finished the job. IBM introduced the P20 Standard Edition and P30 Enterprise Edition subscription bundles, made IBM i on Power11 available only through subscription (excepting serial-preserving upgrades such as E1080 to E1180), and withdrew perpetual P20 and P30 OS licenses effective January 1, 2026. The net effect as of 2026: new IBM i OS licenses are effectively subscription-only across all tiers, while existing perpetual licenses remain usable on existing machines. Subscription terms run 1 to 5 years, are non-cancellable during the term, and bundle software maintenance into the recurring fee, per IBM’s subscription transformation FAQ. The new bundles are also fatter: IBM’s published P30 Enterprise Edition list includes BRMS, PowerHA SystemMirror for i, Db2 Mirror for i, and PowerSC, with P20 Standard Edition positioned around resilience and security tooling. Verify the exact contents against IBM’s current documentation before pricing against them.

Subscription vs. Perpetual: What the Numbers Suggest

Directionally, per IT Jungle’s April 2024 analysis of the post-increase price list: a perpetual IBM i license ran about $15,895 per core plus $318 per user (about $63,600 for unlimited users), against a subscription of roughly $2,356 per core per year plus $80 per user per year (about $4,000 per year for unlimited users). On those figures, IT Jungle put the break-even at roughly five to seven years for P05/P10 shops. Treat the numbers as directional; IBM prices change, and your reseller quote governs.

Perpetual licenses under active software maintenance (SWMA) can convert to subscription at conversion pricing, sold in 3-, 4-, or 5-year terms. From January 1, 2026, new Power10 P20/P30 subscription bundle purchases also include an option to convert non-expiring IBM i licenses on a donor machine at conversion price. That conversion math belongs in the same spreadsheet as the hosting quote.

IBM i Licensing on Power Virtual Server

IBM Power Virtual Serverprices IBM i per core, metered hourly and billed monthly, and the rate includes the operating system license and IBM software maintenance. The part that surprises teams: you cannot bring your own IBM i OS license to PowerVS. IBM’s FAQ states the license is part of the overall workspace cost and “you cannot use an existing license that you already purchased”; even a customer-supplied custom image still pays for the OS on the instance. The partial offset is IBM’s “movable IBM i” option (IBM i MOL): clients with on-premises entitlements under active SWMA can move them to PowerVS at a reduced rate, billed under “mobile core-hour, SWMA paid” part numbers. The discount size is not published; IBM says to contact support.

What the standard rate buys is broad: 5770-SS1 with unlimited users plus a long list of LPPs at no extra charge, including BRMS, HTTP Server, Performance Tools, and Query for i. Three LPPs are separately priced, must be ordered through PowerVS, and per IBM’s documentation cannot reuse existing licenses: Cloud Storage Solutions (5773-ICC), PowerHA for i (5770-HAS), and Rational Development Studio (5770-WDS). Passport Advantage products (IBM’s examples: Rational Developer for i, MQ, Db2 Connect) generally can come along under IBM’s BYOSL policy.

Since mid-2025, PowerVS also supports assignable IBM i virtual software tiers on Power10 and later hosts, from P05 (capped at 1 virtual processor and 64 GB) up to an uncapped P30. The assigned tier sets the OS and LPP rate and can be changed by powering the instance off; billing adjusts automatically. Combined with fractional cores from 0.25 and shared processor pools that avoid additional per-VSI core software charges, this is where most PowerVS licensing tuning happens. Use the Power cloud cost estimator to rough out the per-core math.

PowerVS vs. Managed Hosting: Where Your Licenses Land

The two destinations treat your existing entitlements in nearly opposite ways.

How IBM i licensing works on PowerVS versus an MSP-owned hosted machine
OptionIBM Power Virtual ServerManaged hosting (MSP-owned machine)
IBM i OS licenseIncluded in the hourly per-core rate with software maintenance; no BYOL for the OS (MOL can credit SWMA-active entitlements at a reduced rate)Transfer perpetual entitlements for a per-core fee, buy subscription terms, or use the MSP's monthly licensing offering
Bundled softwareUnlimited users plus a large LPP bundle at no extra charge; PowerHA, Rational Development Studio, and Cloud Storage Solutions priced separatelyDepends on what you transfer or subscribe to; subscription editions carry their own bundles
Serial numberIBM-operated hosts; VSNs assignable to IBM i instances on Power10 and laterProvider machine serial, or a VSN assigned to your customer number so your entitlements can transfer
Third-party (ISV) keysClient responsibility; a new serial usually means new keysClient responsibility; engage every vendor before the move

Managed Hosting: License Transfers, VSNs, and MSP Licensing Models

Managed hosting works on the opposite premise from PowerVS: your entitlements can move. An IBM i license transfer is a permanent move of perpetual entitlements from one machine serial to another. IBM’s transfer FAQ sets the ground rules: the receiving machine must have activated processors available, “banking” transferred entitlements is not allowed, and entitlements on a leased donor machine must be transferred before the lease ends.

Transfers are fee-based per core, and fees rose July 1, 2025. According to IT Jungle’s coverage of IBM announcement AD25-1142, transfer features 1449 and 1450 rose 9 percent to $26,482 per core, while features 1448 and 1451 (which cover same-group and lower-group moves) rose 33 percent to $8,954 per core. At those rates, transfer fees deserve their own line in the business case; transferring is not automatically cheaper than subscribing fresh.

MSPs hosting IBM i on machines they own have three IBM routes, per IBM’s MSP licensing options document: non-expiring licenses where still available, subscription term licenses, or the Service Provider Monthly Licensing offering. VSNs matter here: a VSN on an MSP-owned machine must be assigned to the end client’s customer number, which lets you transfer your own entitlements to the provider’s hardware. Ask IBM or your business partner whether subscription term licenses can move between serials mid-term and whether transfer fees apply to them; the published per-core fees clearly apply to perpetual entitlements.

Third-Party (ISV) Software: The Pitfall That Blows Up Budgets

The line item that most reliably wrecks a migration budget is not IBM’s. In IT Jungle’s cloud migration guidance, the recurring failure mode is third-party licensing that nobody prepared: teams secure keys for the major packages and miss the smaller ones, and when an ISV key is tied to a physical serial number, a move (or a Live Partition Mobility event) changes the serial and invalidates the key. The fix is unglamorous: inventory every vendor product early and engage each vendor before migration, not after.

Two ISV questions deserve particular attention. First, tier-based pricing: whether a vendor will honor PowerVS virtual software tiers, for example keeping P05-tier pricing when your instance runs on an E1080-class host, is vendor-specific, so ask each one. Second, responsibility: IBM’s PowerVS FAQ is explicit that clients are responsible for third-party software licensing, and for OS patching and upgrades. IT Jungle’s advice is blunt: assume some license cost increase in a physical-to-virtual move and budget the time to calculate it.

Old Releases and Service Extension: The Hidden Line Item

Old releases carry a licensing surcharge in the cloud, not just risk. IBM i 7.3 ended normal support on September 30, 2023, and since then PowerVS automatically adds Service Extension pricing to the IBM i charge for 7.3 usage, under per-tier “service extension core-hour” part numbers. IBM i 7.4 is next: IBM announced end of standard support on September 30, 2026, with new 7.4 licenses and subscriptions unavailable after April 30, 2026 and a paid Service Extension running through September 30, 2029. Our IBM i 7.4 end-of-support guide works through that decision.

Service Extension is narrower support at a higher price: IBM stops issuing new Technology Refreshes and provides fixes for serious defects only. On cost, partner materials (UK IBM partner Recarta among them) describe contracts starting near double standard software maintenance and rising in later years; one summary of IBM’s Service Extension document puts the extended 7.3 period at roughly three times base SWMA. Multipliers vary by release, year, and contract: treat them as directional and verify with IBM or a business partner.

Licensing Questions to Settle Before You Sign

Before signing a PowerVS commitment or hosting contract, settle these on paper:

  • Pull your entitlement position from ESS: serials, tiers, processor and user entitlements, and SWMA status per machine.
  • Decide each perpetual entitlement’s disposition: transfer (and at which per-core fee level), convert to subscription, credit through MOL on PowerVS, or retire.
  • Confirm whether SWMA renewals remain orderable on existing perpetual P05/P10 licenses. Public sources do not settle this; get it in writing from IBM or your business partner.
  • Price the target tier, not the current one: a P05 workload on a larger host may bill differently unless PowerVS virtual tiers or explicit MSP terms preserve it.
  • Inventory every ISV product, including small utilities, and get written confirmation of key transfer terms and any repricing.
  • Put the release plan in the cost model: 7.4’s support dates and any Service Extension surcharge are line items, not footnotes.

For an independent second pass before that disposition becomes a contract, our assessment starts with exactly this inventory.

Risks and Common Mistakes

Use caution

Assuming entitlements follow the workload

IBM i entitlements stay with the machine serial recorded in ESS. Without a transfer, a VSN, or the MOL option, moving the workload leaves the licenses behind.

Use caution

Pricing the ERP key and missing the utilities

IT Jungle's migration guidance flags small third-party tools as the licenses that get missed. Any serial-tied key can fail at cutover if the vendor was never engaged.

Use caution

Leaving old releases out of the cost model

IBM i 7.3 usage on PowerVS already carries an automatic Service Extension surcharge, and 7.4 exits standard support September 30, 2026. Release currency is a cost line, not just a risk item.

Frequently Asked Questions

Can I bring my own IBM i license to IBM Power Virtual Server?

Not for the operating system. IBM's PowerVS FAQ states the IBM i license is part of the service cost and you cannot use an existing purchased license, even when deploying your own custom image. There are partial exceptions: the movable IBM i (MOL) option lets clients with on-premises entitlements under active SWMA move them to PowerVS at a reduced 'mobile, SWMA paid' rate, arranged through IBM support, and products acquired through Passport Advantage, such as Rational Developer for i, MQ, and Db2 Connect, can generally be brought under IBM's BYOSL policy. PowerHA for i, Rational Development Studio, and Cloud Storage Solutions must be purchased through PowerVS.

Is IBM i subscription-only now?

For new licenses, effectively yes as of 2026. IBM withdrew new perpetual P05 and P10 entitlements in spring 2024, withdrew perpetual P20 and P30 OS licenses effective January 1, 2026, and made IBM i on Power11 subscription-only, with a narrow exception for serial-preserving upgrades such as E1080 to E1180, per IBM's July 8, 2025 announcements and IT Jungle's coverage. Existing perpetual licenses remain valid on existing machines, and IBM offers conversion deals to subscription for licenses under active software maintenance.

What happens to my perpetual IBM i licenses if I move to the cloud?

They stay tied to your machine's serial number until you act. Moving to PowerVS, they do not transfer: PowerVS pricing includes the OS license, though the movable IBM i (MOL) option can credit entitlements under active SWMA at a reduced rate. Moving to a managed hosting provider, perpetual entitlements can be transferred permanently, including to a virtual serial number on an MSP-owned machine assigned to your customer number, but transfers are fee-based per core: IT Jungle reported fees of $8,954 to $26,482 per core after the July 2025 increases, depending on transfer group. Entitlements cannot be banked for later use, and a leased donor machine must transfer them before the lease ends.

How is IBM i priced on PowerVS?

Per core, metered hourly and billed monthly, with the IBM i license and IBM software maintenance included in the rate, unlimited users, and a large bundle of licensed program products (including BRMS) at no extra charge. Since mid-2025, an assignable virtual software tier (P05 through P30) sets the OS and LPP rate on Power10 and later hosts, with resource caps per tier (P05 allows 1 virtual processor and 64 GB). Fractional cores from 0.25 are supported. Use IBM's pricing estimator for actual figures.

What is a Virtual Serial Number (VSN) and why does it matter for cloud moves?

A VSN is an IBM-issued serial number that is not tied to a physical machine. IBM i entitlements and license keys can live on the VSN, so a partition can move between Power machines without stranding its licenses (announced January 2022 in IBM letter ENUS122-017). In the MSP scenario, a VSN on the provider's machine is assigned to your customer number, which is what allows you to transfer your software to it. PowerVS now supports assigning VSNs to IBM i instances on Power10 and later hosts; whether that enables actual entitlement transfer into PowerVS, rather than serial continuity alone, is not clearly documented, so verify with IBM before planning around it.

What does staying on an old IBM i release cost in the cloud?

More than the headline rate. IBM i 7.3 ended standard support on September 30, 2023, and PowerVS automatically adds a Service Extension surcharge to the hourly IBM i charge for 7.3 instances. IBM i 7.4 exits standard support on September 30, 2026, with a paid Service Extension available through September 30, 2029. Partner materials describe Service Extension pricing starting near double standard software maintenance and rising over time; treat that as directional and verify with IBM. Service Extension also delivers less: fixes for serious defects only, with no new Technology Refreshes.

Will my third-party (ISV) software licenses move with me?

Vendor by vendor. Many IBM i ISV keys are tied to a serial number and sometimes a processor tier, so a new serial (a cloud instance or a hosted machine) usually requires new keys, and a higher-tier host can trigger higher fees. IBM's PowerVS FAQ is explicit that clients are responsible for third-party licensing. IT Jungle's migration guidance: inventory every ISV product early (the small tools are the ones that get missed), engage vendors before migration, and budget for some license cost increase.
