Also keep in mind that if you use the assistant to go from 7.x to 8.x, the system
tablespace will
grow at least 2x. During the migration process, both the 7.x and 8.x data dictionary
exists. For
our Oracle Applications 10.7 instances with 55,000 objects, this was not acceptable.
We instead
exported/imported. This also gave us the apportunity to move to LMTs.

Keep in mind that the actual change to DB internal header blocks
does not occur until they are actually read into the DB. Therefore
I launched an ANALYZE to build statistics which ran 12 - 14 hours.
-- I shall go for full export with direct=y recordlength-65535 and
file=/dev/null which may be much faster then analyze....may be 5-6 hours

I did a 150GB V7.3.4.5 upgrade to V9.2 in less than 2 hours.

Please respond to
ORACLE-L
Can anyone share experience with running database migration assistant
against a 150 GB database (7.3.4) and how long it takes? Don't have the
box
specs yet but I think it is a 3 CPU HPUX with 2 GB Ram and a couple of
unmirrored disks.
