With proper planning and execution, there should be no more issues
w/z/OS1.4 to z/OS 1.11 than any other OS upgrade,
however there are so many changes in the interim (approx 6 years worth),
some of which may not be compatible w/each other, that it would be a
very good thing to peruse the migration manuals in detail for each
interim release.
(1.4-1.5, 1.5-1.6,....).
At least after a detailed perusal of the migration manuals, you will
know where the land mines are.
The same process also needs to be done for the ISV products (version
upgrade/compatibility check). I would suggest beginning this process
now, as it will probably take longer that the z/OS upgrade. My
observation has been that when the O/S is not upgraded regularly,
neither are the ISV products. There are also more likely to be can't get
to here from there issues.
The real issues are:
1) how do I cut over from old (z/OS 1.4/ISV) to new(z/OS
1.11/ISV)?
2) I it fails miserably, how do I go back?
HTH,

I have to update all of my software no matter what route I take. We just
thought if we could do the operating system 1 time, instead of 3 it
would
take us less time.
Am I asking for more problems this way?
Read *ALL* of the migration guide's VERY VERY carefully!!
That is a big jump and you *may* have a lot of work to do on your
existing system to get everything ready for this.
Some of that work may have to be done at conversion time.
Good Luck!

I am running z/OS 1.4 and think of just jumping to z/OS 1.11, if they
finally let me upgrade the software.
I was wondering if anyone out there thinks this is a real bad idea. I
can
isolate a test Lpar and DASD volumes to do this.
I would like some feed back on this idea.
