The RISC-to-RISC migration is the same method we used in the past for 
the CISC-to-RISC migration. It is used when you have to change at the 
same time the hardware and the software.

The target system is loaded only with the microcode and the base OS400 
at the target release.

You backup the entire source system with an equivalent of Save 21 
(including a library created by RTVSYSINF command).

Then, on the target system, you restore user profiles, configuration, 
NONSYS libraries, DLO, other directories of the IFS. And at last, you 
perform a software upgrade for all but the base OS400 with the 
installation media. Of course, you apply the last groups and cum PTFs 
for all the software to be at the same level, and you apply the system 
information with the UPDSYSINF command.
