Thanks again davey

How do I migrate an 8.1.7 db running on AIX 4.3.3
to 8.1.7 db running on AIX5L? (supposing its an ordinary setup
no OPS or RAC)

Do i just copy all the controlfiles, logfiles, datafiles from
AIX 4.3.3 server to AIX 5L server , and startup the database?
Since they have the save Oracle version? but not OS version.

Thanks a lot
