RE: Upgrade disk and OS

Tomasz,

Why not upgrade directly from V5R3 to V6R1? As long as you run
ANZOBCVN first, there shouldn't be any issues.

You didn't tell us the model of your machine, but I will assume it
supports V6R1. You also haven't told us how much free space you have on the
machine to know if you must add disk before upgrading the os. Are you on
V5R3M0 or V5R3M5, as you will need to increase the LIC space on the
load-source prior to upgrading the os if on M0.

Do you currently have one or two raid sets? Are you going to make
the 141 or the 35 drives the load-source? If you do the disks first, I
would make sure you had the last cumulative PTF on V5R3 to make sure those
141GB drives are supported. If you are not current on V5R3 PTFs make sure
you install the link loader PTF before installing PTFs, otherwise when you
load the latest cumulative package of PTFs, you will overflow the link
loader, and then have to reinstall V5R3. Yuk!

Hi

We're planning to upgrade our AS400, it will be two_steps process.
One - upgrade disk from current 8x35 GB to 4x35 plus 4x171 GB
Second - upgrade current OS V5R3 to V5R4 and then to V5R1

How you reccomend to do this process? Which step should be first?

Regards

Tomek
