Homogenous system copy after sap upgrade

Hi,

We recently upgraded to SAP ECC 6, kernel 7.2 UC

I need to perform a system copy to a new system, but my old documentation seems to be obsolete...

These are the steps I try to follow:

1. Sign-on to the Iseries as system admin
2. Install an appropriate kernel library <kernel-lib>
3. ADDLIBLE <kernel-lib>
4. FIXR3OWNS LIB(<kernel-lib>) OBJ(*ALL)
5. CRTR3SYS SID(<sid>) KRNLIB(<kernel-lib>) JRNRCVASP(1)
6. CRTR3INST SID(<sid>) INST(<instance>) ROLE(*CENTRAL)
7. CRTSAPLCL SID(<sid>) CODEPAGE(1100)
8. restore the sap data library from tape
9. Sign-off

point a, b and c worked.

point d. FIXR3OWNS apparently changed to FIXSAPOWNS, but this command doesn't seem to do anything

point e. worked

point 7. changed to CRTSAPINST, there I get the error "CRTR3INST: codepage can not be determined."

Does anyone know if the routine changed? Or what I'm doing wrong?
