Re: Conversion of a 3 TB NON-RAC Database To "ASM" - RAC in 10gR2 ?

use ASM to take a back from ufs to asm file system and use the switch command in RMAN to switch the database files to the new file system. u do not have to restore it to the new file system. Just the switch will take care of the whole thing once u have backed it up. While backing up just take care as to which diskgroup ur files have to go. once the backup is done.
create multiple redologs in the ASM fle system and then drop the one which are in the UFS
once all these have been done then use the switch command.

in R2 it is much easier to switch between file systems.
