I think that I might have mentioned this before but I have successfully
(several times) migrated 2.8 and 2.9 system to a Z9. Admittedly, we didn't
leave the client there for very long, (less than a week) while we moved them
to z/OS, but it ran okay.

wants to purchase a Z9 to replace our aging Multiprise 2003-125 and move our
existing OS to run on the Z9. While we know that OS390 V2R4 has not been
certified to run on the Z9, my management thinks it possible that it

On what factual basis does your management think that this will work?
IBM had compatibility FMID's back in the early zOS releases that would
enable them to run on a zxxx processor. There never was an equalvilent
for OS/390 releases of the operating system.
The fact is OS/390
We are currently running a production OS390 V2R10 on a z9 BC.
BUT, we have to do any HCD changes from a z/OS 1.4 lpar with the z990
compatibility ptfs installed.
I do not know about V2R4.

We attempted to run a soon to be eliminated OS/390 2.6 system on a
z/890 a while back. The system did IPL, but once more than a few users
got on, performance was terrible. We moved them back to the Amdahl that
came off lease until we could upgrade it to OS/390 2.10 (then
supported).
You are running a production environment on an operating system which has not
been supported for a number of years? Is your application environment (CICS,
DB2, what have you) similarly in an unsupported state? I hope, for your sake,
that some application doesn't come along which breaks this

I can only speak for OS/390 2.9 and 2.10 on the Z9 as being able to run, I
have never tried an older version, mostly because we have not had a client
with an older version move to a Z9 (at least not with my help).
I think that there are better ways to accomplish what you need though, I
