RE: System Distribution Directory Entries - Save & Restore

[Evan Harris <spanner@xxxxxxxxxx>]

Hi Scott

I've had this blow up  on me a couple of times now doing V5R3 
upgrades onto 520's. I recall that MQ (and I think Websphere) had 
problems when dong the IFS restore and did not restore correctly. 
Once I get part of the restore having problems I figure I may as well 
do the whole lot manually.

We've now done a number of migrations to 520's running V5R3 by 
planning out what has to be restored rather than doing a slip 
install. Obviously testing is the key, particularly from the 
connectivity viewpoint. Part of our planning is to use OPTION(*NEW) 
to restore only the "real" users bits of QUSRSYS and QGPL.

Another driver has been that this can cut drastically reduce the time 
required for the upgrade. Migrating to a 520 from a 720 (for 
instance) via an upgrade on the 720 first would require a full system 
save, version upgrade inc. cumes, full system save, full system 
restore and that can add up to a few hours/days depending on the size 
of the system. Migrating the box means merely doing a system save 
then a planned out restore process. I've also ignored any hardware 
requirements here.

On the subject of directory entries, I simply wrote a program to 
re-create them when I needed to do this. If you have SMTP addresses 
associated with the directory entries (which can be a bit of a pain 
to extract/migrate) then you may want to check that restoring the 
QAOK* files includes this data.
