Re: V6R1 upgrade from V5R4

Hi, Dave:

**First, you must read this RedBook:

http://www.redbooks.ibm.com/abstracts/redp4293.html

Then instruct the customer read it and follow the procedures described in this RedBook.

Next, the customer (perhaps with your assistance) needs to study the results of running the ANZOBJCVN command (reports), to see what objects on their system cannot be converted, and then take steps to decide what to do about it, if any such objects are found.

Once you have the results of running ANZOBJCVN, you can begin to assess the effort required to do this upgrade. For example, they might have some vendor packages or applications that need to be updated to a V6R1-Ready version. And, some of their own in-house applications code might need to be recompiled to ensure that they have 100% observable code. (This is explained in that RedBook.)

Otherwise, you could end up having an unpleasant "learning experience." For example, you could tell them "it will take 24 hours" and do the upgrade over a week-end, only to discover that some of their mission-critical programs or vendor applications do not have all of the required observability and cannot be converted to run on V6R1. At that point, you would have a very unhappy customer who is "dead in the water". The only recourse would be to restore everything to V5R4 again, assuming you (or they) have a "known good" complete back-up of everything, to allow them to be able to continue running until such time as those issues can be resolved.

All the best,

I know this is a loaded question BUT I had a customer call and ask, If we decide to upgrade to V6R1 from V5R4, how long will it take?

The system is an 8203 E4A with over 58% disk free.

All I am asking is for a ball park figure as to the estimated time to apply and complete the upgrade. I will be downloading the upgrade from IBm and using image catalogs
