iSeries upgrade questions...


I undertook a similar task a last month. We upgraded from v4r3 to v4r5 one
weekend and then next weekend did a save 21 and loaded the tape on the new box
(also at v4r5) and did a restore 21. Whole process worked fine. All I had to do

1/ Delete the SQL packages before the save 21 on the source box
2/ set the system name on the new box to the source system name before the
3/ create the asp2 on the target box before the restore
4/ delete and recreate the device descriptions after the restore (the hardware
resources will probably be wrong)
5/ Create the ip address & host name on the target box after the restore

I found the process easier then doing load of SAP and a database copy. In fact
the documentation from the move is useful because effectively you are doing a
disaster recovery. Logically it is like a situation when you lose a box and only
have the tapes. The nice thing is that if you have a big problem you can just
turn the source machine back on.

Hi Ron,

Thanks for the feedback and the clarification. My question, though not
clear, only referred to SAP data not the entire system. So I took your
first answer as you intended. This will all be done, of course, with our
dev and test systems first - so I am sure there will be more questions to
come as we formulate our plan. And we will check out the notes system.

thanks again,

It was pointed out to me that I have oversimplified it.
To clarify - save "everything" means save all of your SAP data, not GO SAVE
opt 23. For instance, QUSRSYS from V4R4 wouldn't be liked on a V5R1 box.
The SQL pkgs are not needed either - let the V5R1 optimizer build new ones.
See the OSS notes for further help with moving from system to system.

The key thing is upgrade the kernel in your current environment to a level
that is V5R1 certified. If you keep up with the patches, you probably
already have a sufficient patch level. With this, you can save
everything, then restore on V5R1.

On V5R1, your SAPOSCOL job may fail.
after you restore the users will correct this.

You do NOT have to upgrade your V4R4 box to V5R1 before saving/restoring
your environment to a V5R1 partition.

Hi all,

We are moving closer to replacing our 170, 720, and 730 with an 830
(obviously using LPAR). The current systems are all at OS level V4R4.
The new system will come in at V5Rx. Is it possible to migrate SAP to the
new system without first upgraded the old OS from V4R4?

Also, if anyone has done this or something similiar and has any sage advice
it is most welcome.
