V4R4 to V4R5 upgrade.



fixed

I have been given the dubious honour of upgrading our machines (a 170 and a
720) from V4R4 to V4R5.
My boss tells me that heard (although not from a reliable source) that this
upgrade can be tricky.

Having never done an upgrade before I am starting by reading the entire V4R5
Installation Guide, which I hope will tell me everything I need to know.
However, if anyone has done this upgrade and knows of any pitfalls,
problems, prerequisites etc. I'd love to hear about them.

A few questions have occurred to me, so far. I will probably find the
answers as I work my way through the manual but I'll throw the questions out
here anyway, just in case anyone has the answers off-hand.

1. I am told that neither of our machines is partitioned, but I want to
confirm this. Never having had to do this I have no idea what command to
use. If there were partitions, would WRKSYSSTS or WRKLICINF tell me?

2. I know that all temporarily applied PTF's have to be permanently applied
prior to upgrade, but is there any specific level of PTF that must be
applied prior to the upgrade. This question is difficult to put into the
correct words. Basically, I'm upgrading from V4R4 to V4R5, so do I need all
PTF's relating to V4R4 to be applied prior to upgrading to V4R5? Or can I
just apply all PTF's from the most recent V4R5 Cumulative package after I've
upgraded?

All information gratefully received.
Thanks,

Kevin.
