I think all you need to do is a restore of the old database to the new server.

In a nutshell:

Startup nomount new instance
Connec to instance and rman catalog
From RMAN "set dbid ..."
You can get the dbid from the 9i catalog via rc_database

Do a restore

This is from memory ( on my blackberry) so you may want to consult the manual
