Re: V5r4 Upgrade



fixed

Rob,

You'll argue that Larry, Pete, and I do this all the time (as well as several others on the list that regularly contribute) so it's simple to us. True, but it's not all that advanced. If your unsure about the system administration bits, get some help for a couple of days. It's well worth the investment, and I often get IT Directors to use the educational funding for it, since I teach the techniques while we do it. Now the skills stay and you have a well set up system.

is a major reason why I discourage it for those shops that only do this
once ever 7-10 years.

You really have to know what you are doing. It's not a simple matter of
taking MYPGMLIB, MYDTALIB from your V5R4 machine, restoring it on your 7.1
machine and calling it a day. There's so much configuration stored in
both 'traditional' libraries and now in stream files outside of the
/qsys.lib file system.

There's been a few occasions on this list where people have done this
wrong and are still trying to clean up the mess months later.

You can really clean up a system. Also. you now have the ability to move custom work management, communications, and configuration objects into a library of your choice not QGPL, or QUSRSYS. You leave old objects no longer needed behind. Once the new box has the OS loaded, user profiles, communications, work management set up, ect. without the applications and data on it, you can take a base back up. Take this opportunity to create your own install media. Now if you ever rebuild the system use your own install media and most of that will be preset for you! Really neat if you need to build additional LPARs! There are real advantages to the what Kirk suggests if you stop and think of them. The downside, more work initially and a requirement for stronger administration skills. The payoff in the end is much higher than the cost in my experience.
