Hi ScottI'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.

Gord -- Using the instructions in the Backup and Recovery Guide, Chapter 14, "Restoring Previous Release User Data to a New System" has worked well for our company. We have done many migrations for our clients using this checklist. If the 520 was order with feature 0205, then it is already at the "scratch install" state (just LIC and base OS/400 installed). You can start the checklist on page 341 at step 24. If it was ordered with feature 5000 (or is an express box --- IBM doesn't give you a choice of feature), you have to start on page 332 with the scratch install. Once you complete the restores, your QUSRSYS and QGPL will show *BACKLVL, but the next steps are a manual release upgrade to get everything up to V5R3. ---------------------- Scott Scott A.
