IBM Power8 Support After September 2026
IBM i 7.4 standard support has ended, but paid Service Extension remains available through September 2029. See what that buys you and what still requires migration.
IBM i 7.4 standard support ended on September 30, 2026. That did not end every IBM support option. Paid Service Extension began October 1, 2026 and is planned through September 30, 2029. The hard limit is the release itself: Power8 cannot run IBM i 7.5 or 7.6, so the extension buys planning time without removing the need for a migration decision.

The IBM i 7.4 ceiling
IBM i 7.5 does not install on Power8 hardware at all ... it requires Power9 or later. That makes IBM i 7.4 the permanent software ceiling for every Power8 system, regardless of how well the hardware is maintained. Service Extension can continue paid support for 7.4, but it cannot turn a Power8 into hardware that supports a newer release.
IBM i 7.6 is worth flagging specifically: it requires Power10 or Power11 hardware and does not run on Power9. If you are planning a migration off Power8 and want to land on hardware that supports the current IBM i release without a second refresh in a few years, that argues for skipping Power9 entirely ... see our migration comparison.
Security and firmware implications
Past a model's hardware end-of-support date, IBM stops issuing firmware updates for that model under standard support. Third-party maintenance can supply parts and break-fix service, but it does not restore IBM firmware development. IBM i 7.4 Service Extension is a separate paid software agreement. Confirm its defect and fix coverage with IBM before treating it like the former standard-support PTF stream.
Application compatibility risk
Independent software vendors set their own IBM i 7.4 support rules. An IBM Service Extension contract does not require an application vendor to keep certifying new releases on 7.4. Confirm each critical product's support window, license transfer rules, and target-release requirements before deciding that the extension gives you three full years.
The real cost of continuing to maintain
Staying on Power8 is not free, even before a hardware failure. Ongoing TPM contract costs, the opportunity cost of running a software ceiling five to six IBM i releases behind current, and the compounding risk of an unpatched security exposure all accumulate quietly. None of that means migration is automatically the right call on any given timeline ... but it does mean 'do nothing' has a real, growing cost, not a zero one. See our maintenance page for how to responsibly extend Power8's life, and our migration options page when you are ready to plan the replacement.
Price the extension and replacement at the same time
A useful decision compares twelve to twenty-four months of maintenance and risk against a configured Power 10 or Power 11 replacement. Research providers in the IBM reseller directory and ask each one to separate hardware, software, services, support, and migration costs.
