Better idea, which I've done recently. Upgrade DB to 8.1.7 then to
10.2, approximate time 3 hours. Then use Transportable database to move
datafiles to AIX, convert them with RMAN & restart your db. This entire
process on HP-UX to AIX took 18 hours total for a 700GB database. Would
have been faster if we had paralleled things.

To "parallelize" you could use limit the dump files to, say, 500MB
dump files. (filesize parameter)
Ftp the files and start the import while the export is still running.
Of course - test a couple of times before actually scheduling. :)
