Is it possible to run AIX 3.2 on more up-to-date RS/6000 hardware? I
have a legacy RS/6000 99J that is running AIX 3.2 and I am wondering
if I can move rootvg and the other volume groups onto tape and then
restore the system, in its entirety, onto newer hardware. We are
running some old Pick databases that we need to keep, and they only
will run on AIX 3.2.

Thanx in advance.

I think you will find that most newer systems required either 4.3 or
5.1. The older OS's have no support for the new hardware. IBM does a
good job of making the new OS's compatible with old hardware but they
are not writing new code for the old OS's to support the new hardware.

/does/did/. AIX 5.2 has dropped support for all MCA machines and a
number of early PCI ones e.g. the F40. Since I use old stuff which has
been demoted from production status for testing, this leaves me with
nothing I can test 5.2 on.

What about setting up an LPAR partition on a AIX 4.3 machine and
running the AIX 3.2 image within that partition?

LPAR requires AIX 5.1 on Power4 hardware. So don't even start to think
about going there!
Denis has already said it: newer hardware normally requires a version of
AIX which is current at the time of its introduction. IBM normally needs
to apply maintenance to AIX as well, so it's certainly not going to do
this for versions of AIX which have gone out of support.

A 3.2 kernel is going to issue instructions that will work on RS/6000's, but do
not
work or are not emulated on the newer hardware. LPAR will not help you. Now, if
there
was an AIX Virtual Machine (VM) operating system, it could emulate those
instructions,
but I would ask, why? A lot of effort to accomplish what goal?
