IBM i Operating System and Version Management

When should we upgrade our IBM i version?

Upgrade when support timing, target Power hardware, security requirements, third-party software compatibility, or application modernization makes the current release a constraint.

Answer

The decision should be planned around the full stack: IBM i release, PTF groups, firmware, HMC, ISV products, backups, application testing, and rollback. A version upgrade is safest when it is treated as a controlled project, not routine maintenance.
