Re: save and restore to do OS upgrade -- MIDRANGE-L

Pete,

I don't use directory entries. I try to stay away from any of that
proprietary system stuff. Especially for email. I haven't use IBM's SMTP
*cough* system for years.

The only thing I save that's from the "system" are my HTTP configs in
library QUSRSYS (QATMHINSTC all members). Anything else I use (JOBDs, etc)
are saved in user libraries and IFS directories (my own, not IBMs) and
restored if needed.

TCPIP settings take minutes to set up. Point it to your firewall, create
the interfaces for my web servers (I run each on their own IP), start them
and go. And of course, set up DNS properly in CFGTCP option 12... an often
overlooked setup for most customer's systems I've worked on.

I don't use host table entries unless needed... so a max of 1 for the
system name. I do have one other for internal web services so I can point
that to any system I want if needed. But what's that? Another 30 seconds?

Like my PC, I want to make it so that if it blows up, I can get a new piece
of hardware and OS and restore and be up and running in less than a few
hours.

Honestly, it takes longer for me to set up a new PC than the IBM i. I've
done it at least 5 times on each.

Brad,

It's do able, but there are quite a lot of issues to be aware of.
What are you doing with QUSRSYS? That is a system library, and if you
don't move it, you didn't bring over your TCP settings, your Directory
entries, etc. Also, for the IFS, are you not bringing anything over, or
are you over writing stuff in their?

I have done many of these, and I do it basically as a
Migration/Upgrade. Note the order, migration then upgrade. On a simple
system your way will work, but if you want to do it right. You put the new
system with LIC and OS *ONLY*. Run your restore 21, and then when that is
done, do an upgrade to the latest release over what you just restored.
This will insure the latest IBM software is totally installed.

I would do a CHKPRDOPT *OPSYS on the systems you restored Brad and
see if you have any issues.

Larry,

I may be in the minority, but I have done it.. more than once. Just did
it from V5R4 to V7R2.

But, I don't do system saves for that. I do the same thing I do on my
PCs. I save only "non system" programs, objects and data. That way I just
take a fresh machine, restore everything and go.

I save everything to a couple different local PCs as save/zip files, and
also upload them to 2 cloud drives as backups.

PC restoration takes about 2 hours. It's reinstalling programs (like
Quickbooks) that takes the most time. but as more applications move to
the cloud, it makes this even easier. QB is probably the only one I don't
move to the cloud yet. (Multiple companies is easier and cheaper on a PC
program).

IBM i restoration takes even less time... FTP the save files up, RSTLIB,
maybe add a couple settings, start HTTP servers and go.

Once in a while there are IFS authority issues to work out, but those are
minor.

Hello all,
I know how bad this is to do for about a hundred
reasons, but I want to know if it is even possible. I have a
satellite office that wants to perform a full save at 5.3 (don't ask),
then restore it to a 7.1 system. I was always under the impression
that you could skip on version but no more. So that they could go from

5.3, skip 5.4, and land on 6.1.

But 7.1 does not jive with my understanding of what is possible.

Thanks, Larry
