RE: Migrating 3TB size database from HP to AIX, also 9i to 10g.

Just a word of caution - I haven't used datapump a lot, but the few times I have used it I was very disappointed with its performance - it took MUCH longer than good old exp/imp. I don't have time to review my notes right now and give you the specifics of exactly how I ran it with my timings and all the bugs and tuning notes I found, but just be sure to do some research first and beware that it's not necessarily true that datapump speed > exp/imp speed so test it for your specific situation - as usual, it depends.

Regards,
Brandon

Once you get to 10g on HP you can use datapump which is much faster
