Lizzette:
With OS upgrades I pretty much follow you.
What seems to be lost in the haze is when you have major upgrades
(like COBOL or LE). With those two I will take exception.
15 or 20 years ago we had gone through the upgrade. After the upgrade
(with a LOT of battle wounds) I swear IBM hired a lawyer to write the
guide. I also swear with real words that LE should have been taken
out back the barn and shot.
Has it gotten any better over the years well a bit (COBOL and LE) are
the two worst violators of IBM at their worst. I will put it simply,
COBOL and LE are the biggest use of lying IBM has produced to date.
You still need to be a lawyer to read (and understand) their
migration "guides" .
Then on top of that IBM for years refused to produce a MSG & Codes
(they finally did so but it really doesn't (IMO) live up to IBM
documentation standards. Their standard refrain for years was the
message(s) is self documenting(?! my thoughts as well). Its been 20
years but the first call I got in the AM was WTF does this message
mean. I looked at it and it left me with wonderment WTF IBM was
thinking when they wrote the message. I told the programmer I would
get back to them. I called in and opened a PMR. Level 1 was stumped
just as much as I was. So he forwarded it to level 2. Level 2 got
back to me about 2-3 days later and I asked for a clarification and I
got the run around. I was extremely nice to the guy. He would
(could?) not explain the message, Later on that day I got a call from
another knowledgeable guy this time it was all double talk. A day
later I got a call from a guy that seemed to at least ask the right
questions. I got a conference call going and finally got down to a
reasonable explanation (to many FD's).
The COBOL migration manual talked in lawyer talk about certain items
that may occur in a COBOL program. That should have been simply
written instead it was in legalize. We had *SO MANY* issues with that
conversion it was the biggest conversion hassle I have ever had with
anything IBM in my 40++ years with IBM. I have done VS1 to MVS
conversions that were so smooth, they were a breeze. One was so
simple, no JCL changes only one recompile as the vendor forgot to set
the RC (in r15) when they left the program.
Compare that to the vast number of compiles for COBOL (and LE) (and
the poor migration guides IMO)it was almost fun. I am happy that I am
out of the rat race now and don't have to put up with the COBOL and
LE people anymore.

I would say if you follow the process of FIXCAT listings and
applying what you need on the target system, you should be fine.
Jump in the pool, the water is fine.
Everything will depend on if you have a standalone system where you
can bring it up and fallback.
There are share presentations.
Most shops have IVPs to check out a new z/OS
The Migration Guides are your friends.
Search the archives for IBM Main for z/OS V2.1 installs.

Hi
Should I be looking into the PE or HIPER for z/OS ? If so what
should be
looking into it especially?

Everything is well documented. One overlooked documented item was
the
return code change from LISTCAT of a GDG base with no entries. V1R13
gave RC = 4. V2R1 RC = 0. Documented workaround as well.

<pre style="font-size: 9pt;"><tt>Hi
We are upgrading our operating system from 1.13 to 2.1.
So apart from
toleration maintenance are there any other Things to be looked from
the OS perspective?
Would somebody share the steps taken at your shop ?
