Thanx a lot for the i/p.

Pl let me know is this method works, with diff versions of Oracle? In other words, my source is 8.0.4 and i copy the required datafiles and open the DB on 8.1.7 , will it work? Or any other relevant issues with this version change in source and target DB's?. And apart from datafiles and redo log files do i need to copy archive logs also?. If so do i need to switch manually the log files, before start copying these files?
