IBM i 7.4 End of Support: What IT Directors Should Do Now

IBM i 7.4 end of support arrives on September 30, 2026. Your systems will keep running, but standard fixes and support stop. You have three real options: upgrade to IBM i 7.5 or 7.6, buy IBM’s paid Service Extension (available through September 30, 2029), or refresh or relocate the workload. Your Power hardware generation decides which options are open.

For most IT Directors this is not a technical surprise. It is a budget, staffing, and risk decision landing at the same time as 2027 planning. Here is how to make it quickly and defensibly.

Key takeaways

• IBM i 7.4 leaves standard support on September 30, 2026. Nothing shuts off, but your risk and audit exposure grow every month you stay.
• IBM’s IBM i 7.4 Service Extension runs October 1, 2026 through September 30, 2029. Treat it as a bridge with an end date, not a destination.
• Hardware sets the ceiling: Power8 stops at 7.4, Power9 stops at 7.5, and 7.6 needs Power10 or Power11.
• IBM’s announced 2027 price increases on IBM i software maintenance make delay more expensive, so get quotes before year end.
• Skills, not software, is usually the constraint. Plan the upgrade around who will actually do the work.

What does IBM i 7.4 end of support actually mean?

It means IBM stops providing standard defect support and new fixes for 7.4 under normal Software Maintenance. It does not mean your system stops working, and it does not mean IBM walks away if you pay for extended coverage.

The practical impact shows up in three places:

• Security and audit. Auditors and cyber insurers increasingly ask whether your operating systems are in vendor support. “Out of support” is a hard answer to defend.
• Vendor certification. ERP, HA/DR, and security tool vendors tend to follow IBM’s support lifecycle. Expect fewer of them to certify new versions on 7.4.
• Fix availability. If you hit a defect after September 30 without Service Extension, your path to a fix gets slow and uncertain.

What are my options after IBM i 7.4 end of support?

You have four realistic paths. The right one depends on your hardware, your application vendors, and how much in-house IBM i expertise you can count on over the next 12 months.

Option	Best fit when	Watch out for
Upgrade in place to IBM i 7.5	You are on Power9 or Power10 and the hardware has useful life left	A second upgrade later if you want 7.6 features; confirm vendor certification
Upgrade to IBM i 7.6	You are on Power10 (FW1060 or later) or Power11, or refreshing hardware now	Firmware prerequisites and application testing time
Buy IBM i 7.4 Service Extension	You need time: a vendor is not certified yet, or budget lands next fiscal year	Added cost on top of maintenance; easy to let a bridge become permanent
Refresh or relocate the workload	You are on Power8, or you want to get out of running the hardware	Migration planning, data movement, and cutover windows

Which IBM i release can my Power server run?

Your processor generation sets the ceiling. According to IBM’s hardware planning pages, IBM i 7.6 requires Power10 (minimum firmware FW1060) or Power11, and IBM i 7.5 supports Power9, Power10, and Power11 but not Power8.

• Power8: IBM i 7.4 is the ceiling. Any supported future requires new hardware or a hosted environment.
• Power9: IBM i 7.5 is the ceiling. Upgrading now buys time, but plan for a hardware refresh if you want 7.6.
• Power10 and Power11: Both 7.5 and 7.6 are open to you. 7.6 is the longer runway.

If you are not sure what you have, start there. Our team’s field notes on Power10 installs are a useful read on what the upgrade actually involves.

Should I buy IBM i 7.4 Service Extension or upgrade now?

Buy Service Extension only when you have a specific blocker and a dated plan to remove it. Otherwise, the money is usually better spent on the upgrade itself.

Service Extension makes sense when an application vendor has not certified 7.5 or 7.6, when a hardware refresh is already approved for next fiscal year, or when a merger or ERP project has frozen change. In each case, write down the exit date when you sign.

How do I plan an IBM i upgrade with a thin team?

Plan around people first. In the 2026 IBM i Marketplace Survey, 69% of respondents named IBM i skills a top concern, ranking it above cybersecurity for the first time. If one or two people hold your IBM i knowledge, the upgrade plan has to protect them from becoming a single point of failure.

Use this five-step checklist to get from “we know” to “we have a plan”:

1. Inventory. List every IBM i partition, its release, its Power generation, and its firmware level.
2. Check vendors. Confirm each application and tool vendor’s supported releases for 7.5 and 7.6.
3. Pick a target per system. 7.5 in place, 7.6 in place, new hardware, or hosted, based on the table above.
4. Decide on a bridge. If any system cannot move before year end, price Service Extension and set an exit date.
5. Staff the work. Decide what your team does and what a partner does, including testing, cutover, and rollback.

Before you start any upgrade, confirm your high availability and backup posture. A tested recovery point is the cheapest insurance you will buy all year. If you run MIMIX, our overview of Assure MIMIX 10 covers what to check.

How Clear Technologies helps

Clear Technologies has supported IBM Power and IBM i environments for more than 30 years as a premier IBM partner based in Addison, Texas. We help IT Directors make this decision and then carry it out:

• Release and hardware assessment across every partition, with a recommended path per system through our IBM i technical services team.
• Upgrade planning and execution, including firmware, PTFs, testing, and cutover support.
• Hosted and managed options through IBM Power IaaS and managed services when you would rather not run the hardware.
• Ongoing coverage through IBM i managed services, so your upgrade does not depend on one or two people.

Frequently asked questions

When does IBM i 7.4 support end?

IBM ends standard support for IBM i 7.4 on September 30, 2026. Systems keep running after that date, but new defect fixes and standard support stop. IBM offers a paid Service Extension from October 1, 2026 through September 30, 2029 for organizations that need more time to upgrade.

Can I keep running IBM i 7.4 after end of support?

Yes. Your servers and applications continue to run. The risk is operational: no new fixes under standard support, growing security exposure, and fewer vendors certifying their software on an out-of-support release. If you stay, buy IBM’s Service Extension and set a firm upgrade date so the extension does not become permanent.

Should I upgrade to IBM i 7.5 or 7.6?

It depends on your hardware. IBM i 7.6 runs only on Power10 (firmware FW1060 or later) and Power11. Power9 servers top out at IBM i 7.5. If you plan to refresh hardware in the next two years, going straight to 7.6 on new hardware avoids a second upgrade later.

What if my IBM i runs on Power8?

Power8 cannot run IBM i 7.5 or 7.6, so 7.4 is the ceiling. Your realistic options are a hardware refresh to Power10 or Power11, moving the workload to a hosted or cloud IBM i environment, or buying Service Extension time while you plan. Each path has different capital, operating, and staffing trade-offs.

How much does IBM i 7.4 Service Extension cost?

IBM prices Service Extension through IBM representatives and Business Partners, and pricing varies by system and entitlement. Expect it to cost more than standard support. Also note that IBM has announced 2027 price harmonization that raises IBM i software maintenance, so get quotes before year end.
