** Why upgrade at the same time as OS move?
Consolidated application testing. The new environment only has to be
tested once and it is tested thoroughly so there is minimal probability
of problems after go-live. This was preferrable to us rather than
having to go through all the effort of upgrading to 10g on an old,
slower box and having to optimize and troubleshoot everything there, add
RAM to support the needs of 10g, and do full application testing only to
repeat all the optimization and testing again when moving to AIX.
** LMTs?
Again, why not do it all at once as long as it's well tested? I'm not a
masochist - if I can consolidate/eliminate work, I do (especially if
it's after hours).
** Cleaner dictionary?
Check Metalink for the bugs that only affect 10.2.0.3 data that was
upgraded from 8i - sure glad that I don't have to worry about those!
That's only one (maybe two) examples, but I'm sure there are more. I
don't have any examples of "dirty" dictionary data - it just seems to me
that it would be cleaner, less fragmented, etc. to just start with a
nice dictionary in the new version. Why not?
** How will I tell which change caused the bug?
By troubleshooting as usual, and by thoroughly testing the new
environment prior to go-live to detect any bugs before it's too late.
** Question for you
Why NOT use exp/imp? You act like it's evil. The only reason I can see
not to use exp/imp is if you are under time constraints that are tighter
than the amount of data you need to upgrade.

Brandon
