DEV, TEMP and VER should most likely not be copied, but should be updated if
needed.
OMVS.ZOSZ1B.** should not be copied from the z/OS 1.11 image. They should be
copied from the z/OS 1.13 image.
By copying from the z/OS 1.11 image, you are "down leveling" your production
image
Otherwise, it looks pretty complete to me. /usr/lpp/..... seems to reside in
the ROOT file system, so you should be pretty much good to go.
I would suggest doing the non-shared 1.11 system first and work out any issues
before attempting the two shared 1.11 system.
After all systems are at 1.13 I would *STRONGLY* suggest a hard look at SYSPLEX
file SHARING. This is called out as an optional migration action
In the 1.13 migration manual (z/OS MIGRATION Version 1 Release 13 (GA22-7499).
In my case, I have a separate image that is *NEVER* IPL'ed for maintenance. All
PTF application, .. is done to this image.
The maintenance image is then "cloned" w/DFDSS to a TEST image. After IPL,
checkout, and some elapsed time for "aging",
the maintenance image is again "cloned" to *ONE* of the production images.
After another suitable elapsed time, all other images are upgraded from the
maintenance copy.

Subject: z/OS System migration in Sysplex
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.
