Re: i5 OS upgrade - from V7R1 to V7R2

Items that have been a big concern include the levels of WAS supported and
the Java engines supported.
There is not one java engine that shipped with V5R4 that is supported on
7.2. There is one that you could have downloaded for V5R4 that will work
on 7.2. But, like who can download V5R4 stuff anymore? So the fence
straddling vendors are going to have to make a leap as to what OS levels
they are going to support. Those that are actively upgrading and writing
checks. Or those that are dormant and probably even grumble about paying
maintenance.

Often these concerns are alleviated by upgrading the version of software
from your vendor.
Domino required upgrading to version 9 as no versions of Domino 8 are
supported (I tried).
IBM is abandoning their Quickr product and want you to migrate over to
Connections. We're working on that but we're not going to run it on IBM i
anymore. As soon as we uninstall Quickr from that lpar it's going to 7.2.
IBM Sametime is not an upgrade from 8 to 9. It's an uninstall and
reinstall from scratch. It sounds quite daunting, as compared to
something simple - like an SAP installation. :-) But we're thinking
about tackling that beast. This is the reason we've not upgraded our main
ERP lpar. In a period of lunacy we installed Sametime in that same lpar.
Infor's Webtop will have to be upgraded because of the WAS requirement.

You say your hardware should be good. That was a huge show stopper for us
in going from 7.1 to 7.2. Even though a 9117-MMA is supported a vast
majority of the expansion units and cards we were using were not. We were
able to get a couple of guested lpars upgraded as long as they used no
unsupported cards.

All of our show stoppers were covered in the Memo To Users except what
levels of java, WAS, etc each vendor required.
