Database Software

Hi,

We have large database around 20TB. We want to migrate (move) the database from one server to other server. We do not want to use standby option.
1) How can we move database using RMAN in less downtime
2) Other than RMAN is there any option is available to move the database to new server

For option 1 (restore using RMAN),

Whether below options are valid?
If this option is valid, how to implement this?


1) How can we move database using RMAN in less downtime
a) Take the full backup from source (source db is up)
b) Restore the full backup in target (source db is up)
c) Take the incremental backup from source (source db is up)
d) Restore incremental backup in target (source db is up)
e) Do steps c and d, before taking downtime (source db is up)
f) Shutdown and mount the source db, and take the incremental backup (source db is down)
g) Restore last incremental backup and start the target database (target is up and application is accessing this new db


database version: 10.2.0.4
OS: SUN solaris 10
