Cloning is an option, but if you are in archivelog mode and using rman
backups, then you can also use them to minimize downtime.
Or if you are using Enterprise Edition, then Data Guard physical
standby is a good option and quite easy to set up using data guard
broker.
If you are on standard edition, then the same thing can be done
manually using RMAN... restore database from backup on new server, but
don't open it. This can be done before switching and while the old
database is still open. Until you are ready to switch, backup
archivelogs on old server, copy backup to new server, catalog backup
and recover database. If you are ready to switch then shutdown&mount
the old database, backup the final archivelogs (including online log)
and recover the database on new server and open the new server.
