An approach to managing software delivery that makes it possible for IBM-supplied distribution media to deliver entire (or parts of) licensed programs at existing releases with or without a new release of i5/OS. Existing licensed programs that are enabled for mixed releases but that have no new function are not rebuilt. They are not renewed with a new release of the operating system. Similarly, optionally installable parts of licensed programs that are enabled for mixed releases are not rebuilt or are not renewed with each new release of its base licensed program. Enabled licensed programs that remain at earlier releases are compatible and function with the new release of the operating system.
