IBM i 7.4 Support Ends on September 30, 2026. Is Your Upgrade Plan Ready?

For many IBM i shops, operating system upgrades tend to fall into the category of "important, but not urgent." Systems are stable, applications continue to run reliably, and there are always other projects competing for attention.

However, there is one date that IBM i administrators and IT leaders should have firmly marked on their calendars: September 30, 2026. That's when standard IBM support for IBM i 7.4 comes to an end.

While many organizations are aware of the deadline, what is less well understood is what happens next, what the alternatives are, and why upgrading to IBM i 7.5 or IBM i 7.6 makes sense even if your current environment appears to be running perfectly well.

The reality is that this is about much more than simply staying on a supported operating system. It is about managing risk, controlling costs, maintaining security, and ensuring your IBM i environment remains aligned with IBM's future direction.

What Are Your Options After September 30, 2026?

Organizations running IBM i 7.4 effectively have three choices.

The first, and for most businesses, the most sensible option, is to upgrade to IBM i 7.5 or IBM i 7.6 before support ends.

The second option is to remain on IBM i 7.4 and purchase IBM Service Extension. IBM has confirmed that Service Extension for IBM i 7.4 will be available until September 30, 2029, providing up to three additional years of support coverage for organizations that need more time to complete an upgrade project.

The third option is to continue running IBM i 7.4 without support, or by taking alternative 3^rd-party support. While some organisations choose this route, it can carry obvious risks. If a problem occurs that requires IBM assistance, support options become limited. Software vendors may reduce or withdraw support for older releases, and auditors increasingly question the use of unsupported operating systems for critical business applications.

For most organizations, the decision ultimately comes down to balancing cost, risk, and future requirements.

The Hidden Cost of Delaying an Upgrade

At first glance, Service Extension can seem like an attractive option. It allows organizations to defer an upgrade project while maintaining IBM support coverage.

However, that flexibility comes at a price.

IBM's Service Extension pricing for IBM i 7.4 increases each year after standard support ends:

Period	Service Extension Premium
Year 1 (Oct 2026 - Sept 2027)	150% of annual SWMA
Year 2 (Oct 2027 - Sept 2028)	200% of annual SWMA
Year 3 (Oct 2028 - Sept 2029)	250% of annual SWMA

In practical terms, an organization paying $1,000 per core annually for SWMA would pay an additional $1,500 per core in the first year of Service Extension, increasing the total annual cost to $2,500 per core.

For many businesses, those escalating support fees quickly become difficult to justify, particularly when compared with the benefits of moving to a supported release and continuing to receive ongoing enhancements and innovation.

Service Extension can be a valuable safety net, but it is generally best viewed as a short-term bridge rather than a long-term strategy.

Why Staying on a Supported Release Matters

IBM i has earned its reputation as one of the most reliable and resilient enterprise operating systems available. Many organizations continue to run workloads that have been supporting the business for decades.

That stability is a major strength, but it can sometimes create a "why change?" mentality. The answer is that while your applications may not be changing dramatically, the world around them certainly is.

Cybersecurity threats continue to evolve. Regulatory requirements become more demanding. Hardware generations advance. Businesses expect greater integration with cloud services, modern applications, analytics platforms, and external partners.

Remaining on a supported IBM i release ensures that your environment can continue to adapt to these changes while benefiting from IBM's ongoing investment in the platform. 

Perhaps most importantly, supported releases continue to receive new Technology Refreshes, security enhancements, hardware support, and operational improvements. Once a release exits support, that innovation effectively stops.

Security Expectations Have Changed

Security has become one of the strongest drivers for operating system upgrades across the IBM i community.

Today's IBM i servers are rarely isolated systems. They are connected to networks, users, cloud services, web applications, and external organizations. As a result, security is no longer simply a technical concern. It is a business concern.

Executives, auditors, cyber insurers, compliance teams, and customers increasingly expect critical systems to be running supported software.

IBM continues to enhance security capabilities in supported releases through improvements to authentication, encryption, auditing, certificate management, and access controls. Organizations running current releases benefit from those improvements as they become available.

Even if your current security posture appears strong, remaining on a supported release helps ensure that it stays that way.

More Than Just Another Upgrade

One misconception about IBM i upgrades is that they are primarily about receiving new features. In reality, many of the benefits are operational.

IBM i 7.5 and IBM i 7.6 continue IBM's strategy of simplifying system management, improving usability, and making it easier for organizations to modernize at their own pace.

Administrators benefit from improved management tools, expanded automation capabilities, and a more modern administration experience. The platform continues to evolve in ways that reduce complexity and help IT teams operate more efficiently.

At the same time, IBM continues to invest heavily in areas that matter to modern businesses, including security, cloud readiness, application integration, open-source technologies, and support for contemporary development practices.

You do not need to be planning a major modernization project to benefit from these improvements. Simply remaining on a supported release ensures your environment remains aligned with IBM's roadmap and future investments.

Why Some Organizations Will Choose IBM i 7.5

For many businesses, IBM i 7.5 will represent the most straightforward upgrade path. It is a mature release, widely adopted across the IBM i community, and supported by a broad ecosystem of software vendors, business partners, and service providers.

Organizations looking for a relatively low-risk upgrade while maintaining a strong support lifecycle may find IBM i 7.5 to be an attractive option. It delivers the benefits of a current release without requiring organizations to move immediately to the latest version.

Why Others Will Go Straight to IBM i 7.6

For organizations planning for the long term, IBM i 7.6 offers an obvious advantage: longevity. As IBM's latest major release, it provides the longest available support horizon and positions organizations to take advantage of future Technology Refreshes for years to come.

Businesses planning hardware refreshes, cloud migrations, modernization initiatives, or broader infrastructure investments may decide that moving directly to IBM i 7.6 makes the most sense. It reduces the likelihood of another major operating system upgrade being required in the near future and provides a platform aligned with IBM's latest strategic direction.

Start Planning Before It Becomes Urgent

One of the biggest mistakes organizations make is assuming they can wait until support is almost over before beginning their upgrade planning. Successful IBM i upgrades require preparation.

Applications need testing. Hardware compatibility may need reviewing. Third-party software vendors may need to certify support. High availability and disaster recovery environments should be validated. Internal change management processes often require approval and scheduling. The organizations that start planning early have the greatest flexibility and the fewest surprises.

With standard support for IBM i 7.4 ending on September 30, 2026, the conversation is no longer whether an upgrade will eventually be required. It is simply a question of timing. Whether your destination is IBM i 7.5 or IBM i 7.6, upgrading provides benefits that extend far beyond maintaining support eligibility. It helps reduce risk, strengthens security, preserves access to IBM innovation, and avoids the escalating costs associated with long-term Service Extension.

IBM i has remained one of the most trusted enterprise platforms because it continues to evolve while preserving the reliability organizations depend on. Staying on a supported release ensures your business can continue to take advantage of that evolution, rather than paying a premium simply to stand still.
