OS/400 single step upgrades

Single step RISC-to-RISC upgrades are supported as normal upgrade
procedures. You can find instructions in the software installation publication that
corresponds to the release.
If a new RISC iSeries server replaces an existing RISC iSeries server, order
#0205 RISC-to-RISC Data Migration against the hardware to restrict the preload
of all software except SLIC and the basic functions of OS/400. This allows the
remaining libraries to be migrated from the existing system to the new system.
