RE: Install (or rollback) to previous version of OS

["Jim Oberholtzer" <midrangel@xxxxxxxxxxxxxxxxx>]

You could get the first boot, but then when you go to load LIC with option 2
(clears the system) everything is wiped out.  

You ~can~ accomplish booting from an image catalog but that catalog must be
on another system.  Larry and I do it all the time but there is some set up
and advanced stuff going on that while not hard, is new to many folks.
Google "IBM i network install" and you'll find several redpapers and other
documentation on it.

Evan,

So you are saying you do not think I can download the 7.1 Optical Images
onto the 7.2 partition and then do a slip install from it resulting in a
partition with 7.1?

Hi John

To be clear, what I understand you want to do is load V7R1 media into a
V7R2 LPAR and then run the upgrade (or whatever) process in such a way that
the system is reverted to V7R1.
As far as I am aware what you are asking is not possible. You can't back
level an Operating System to an older version once updated.

if you want a V7R1 LPAR you will need to build one from scratch and restore
the data to it somehow (I've never tried this)

I am wondering if you need V7R1 Extended support to be entitled to download
the media and patches now that it is out of support.
