Don't forget about configuration objects (including subsystems, job queues, 
line, controller and device descriptions - may or may not be identical), system 
values, job descriptions, classes of service, user objects in QGPL, QUSRSYS, 
QSYS, etc, host table entries, job schedule entries, stored procedure 
definitions, user profiles, system directory entries, document library objects, 
differences in licensed program products, user programs that access system 
tables (they've changed - QADBXREF now has an enormous record length) and hard 
coded device names in programs. We recently did an upgrade similar to yours and 
successfully went from V3R1 to V4R2 without a hitch after a disk crash on the 
old box. Luckily, my partner in crime had a couple of weeks of up-front work 
already done though and we were pretty well ready to do it anyway. Don't tell 
Al, but even though we couldn't follow the roadmap, no important anatomical 
parts fell off. Did some serious homework first though.
