No, and no.
No, there is no z/OS system which work on z14, but would not work on EC12.
Note: z9 is different (much older) animal - it is not possible to IPL
z/OS 2.2+ (I'm not sure about 2.1) on z9. BUT THIS IS NOT THE CASE.
No, I don't refer to any "ALS". To be precise, for any mainframe OS
there's a version which is supported on both z14 and EC12.
At least, the most current z/OS (2.3) and z/VM (7.1), and z/VSE (6.2) ,
and RHEL (7) do support both z 14 (obvious) and EC12. I'm not sure about
z/TPF and other Linux distros, but I believe this is also the case.
In other words, it would be very hard to run any OS on z14 while the
same OS does not support EC12.

I don’t have the details, but some OS'es will not support the hardware.
Some hardware will not support the OS;es.
E.G. z/OS 2.3 is not supported on z9 (I doubt it would work).
z/VM is your friend. You can mimic older hardware.

Subject: Re: Clarification on using a hardware
It is possible, despite what you mean exactly.
It is possible to set up some LPAR on EC12 and start here any z/OS (or other
OS) currently working on z14. It is possible to start vanilla new OS on the
EC12.LPAR.
Caution: possible does not mean legal. In theory starting licensed software on
spare machine would cause license 'duties', even if you do that hust for fun.
Good excuse could be 'cold backup' - but is it valid reason?

Hi
We recently moved from zec12 to z14 and routers all connections ,storage,
tapes to the new hardware.
So as of now zec12 doesn't have any workload. So it will be just active for
few months. Is it possible to build an LPAR from scratch using the new
machine and move it to zec12 just for a practice and training purpose ?
Regards
Peter
