How can it be disrespectful to suggest that you edited the output when you did
edit the output, unless you want me to accept your Windows account is "XXX"?
I certainly didn't mean to imply that you intentionally altered the output to
confuse the issue, but cut/paste errors are common enough, and the possibility of
multiple upgrade attempts is significant, since, in my experience, if the first 9.x->10.x
upgrade attempt fails, subsequent upgrades will fail with a different error, and it's
likely that you'll need to roll back your database to a snapshot from before the first
failed attempt before attempting another upgrade (you'd also need to fix whatever
caused the initial failure after the rollback is complete).
If GDB_ITEMS can't be created, then the reason is often that the table already exists
(as in an unsuccessful upgrade without rollback), or that some other database reason
exists for the creation failure (quota or storage on SDE tablespace,...). Only the alert
log will tell why (unless you had SDEVERBOSE set, in which case the database error
should have been reported in the upgrade log).
At this point you'd be best off working directly with Tech Support, since they're likely
to have more tools and techniques available than those of us who've only run a few
dozen 9.x-> 10.x upgrades.
