Planning for Power 12: What IBM i Shops Should Do Now

There is nothing to buy or quote for Power 12 yet. Here is what IBM i and AS/400 shops can usefully do today: compare Power 11, check OS support, budget around real quotes, and watch the next-generation signals.

There is no Power 12 quote checklist, because there is no Power 12 product to quote. What follows instead is what an IBM i or AS/400 shop can actually do today, grounded in real, currently-known facts ... not speculation dressed up as advice.

1. Know your Power 11 support window

IBM's tracked pattern is seven years of standard support followed by three years of extended support per Power generation. If you're currently on Power 11 or planning a Power 11 purchase, that gives you a concrete internal deadline to plan a next-generation evaluation around, independent of when Power 12 actually ships.

2. Watch the IBM i 8.1 release, not just the Power 12 announcement

IBM i 8.1 ("IBM i Next") is independently projected for 2028, roughly the same window analysts project for Power 12. A major IBM i release is historically the point where new Power hardware capabilities actually become usable in production, so it is arguably a more useful planning marker than the hardware announcement alone.

3. Budget for ISA continuity, not a rewrite

Every Power generation to date has preserved software compatibility for existing IBM i and AIX workloads. There is no sourced signal suggesting Power 12 breaks that pattern. Capacity and hardware refresh planning is the realistic budget conversation; an application rewrite is not something current evidence suggests you need to plan for.

4. Use Power 11 as the budget baseline

Power 12 has no price, model list, processor feature codes, or software tiers. Power 11 does. That makes Power 11 the only honest quote baseline today. If you are on Power 9, especially an S914-class entry environment, IBM's July 2026 Power S1112 announcement gives you a current-generation comparison point instead of a blank future placeholder.

5. Separate OS planning from hardware naming

The operating-system question is not "Power or iSeries?" IBM Power is the hardware family. IBM i, AIX, and Linux are the operating systems. Before you wait for Power 12, document which workloads run on IBM i, which run on AIX or Linux, whether VIOS is involved, and what support levels each partition needs on current Power 11 hardware.

6. Ask your hardware partner these questions now

Support runwayWhat is my confirmed standard + extended support window on my current or planned Power 11 hardware?
Refresh cadenceWhat lead time does my vendor typically need between a new Power generation's announcement and delivered, configured hardware?
AI acceleration planIf I adopt Spyre-based AI acceleration on Power 11 now, what does my vendor know about upgrade or trade-in options for a future generation?
HMC and management stackIs my current HMC and management tooling version likely to carry forward, based on IBM's past generation-to-generation management requirements?
Power 9 baselineIf I am on a Power S914 or similar Power 9 server, what does a Power S1112 or S1122 quote look like as the current-generation comparison?
Manual dependencyWhich decision truly needs a Power 12 manual, and which can be answered today from Power 11 documentation and current OS support matrices?
