Hello,
We have four system in sysplex with different version of OS. Out of
four systems,
3 system are with z/OS 1.11 and 1 system is with z/OS 1.13.
Out of 3 system with z/OS 1.11, two system sharing USS as well and one not.
Now we have requirement of migrating z/OS 1.11 system to z/OS 1.13 systems,
so that all four system will be running z/OS 1.13.
for doing this,
a) I will be using same RES volume for current z/OS 1.11 system which
currently z/OS 1.13 system is using. So that all system will use z/OS 1.13
RES pack.
b) I also copied and modified parmlib member of z/OS 1.11 system to z/OS
1.13 system parmlib.
c) Now major challenge I feel is migrating USS of z/OS 1.11 system to z/OS
1.13 system. For doing this, I made following changes BPXPRMFS parmlib
member of z/OS 1.11
system sharing USS
i) Copied OMVS.ZOS1B.ROOT to OMVS.ZOS1D.ROOT from z/OS 1.11 system
ii) Copied OMVS.ZOS1B.SIGYROOT to OMVS.ZOS1D.SIGYROOT from z/OS 1.11
system
iii) Copied OMVS.ZOS1B.SHPJROOT to OMVS.ZOS1D.SHPJROOT from z/OS 1.11
system
iv) Copied OMVS.ZOS1B.SIBMROOT to OMVS.ZOS1D.SIBMROOT from z/OS 1.11
system
v) Copied OMVS.ZOS1B.AFOROOT to OMVS.ZOS1D.AFOROOT from z/OS 1.11 system
and changed mount point like below.
A) OMVS.ZOS1B.ROOT - MOUNTPOINT('/$VERSION') TO OMVS.ZOS1D.ROOT
B) OMVS.ZOS1B.SIGYROOT -- MOUNTPOINT('/usr/lpp/cobol') TO
OMVS.ZOS1D.SIGYROOT
C) OMVS.ZOS1B.SHPJROOT ---MOUNTPOINT('/usr/lpp/hpj') TO
OMVS.ZOS1D.SIGYROOT
D) OMVS.ZOS1B.SIBMROOT ---- MOUNTPOINT('/usr/lpp/pli') TO
OMVS.ZOS1D.SIGYROOT
E) OMVS.ZOS1B.AFOROOT -----MOUNTPOINT('/usr/lib/ssh') TO
OMVS.ZOS1D.SIGYROOT
Now What else steps do I need to follow to complete this USS migration. Do
I need to copy etc, dev,temp, var file system from z/OS 1.13 system to z/OS
1.11 system.
