Migrate existing database to ASM.

Question

Hello all,
I am currently working on stand alone database and i want to migrate my existing database to ASM.
i am trying it via RMAN and i did the following changes in my database :-
SQL>alter system set control_files='+data' scope=spfile;
System altered.
SQL>alter system set db_create_file_dest='+data' scope=spfile;
System altered.
SQL>alter system set db_recovery_file_dest='+data' scope=spfile;
System altered.
here "data" is the disk group
than i shutdown the db and started in no mount mode
so i can start the migration via RMAN
in rman i did the following things:-
D:\>RMAN target=orcl
Recovery Manager: Release 10.2.0.1.0 - Production on Fri Aug 28 01:13:02 2009
Copyright (c) 1982, 2005, Oracle. All rights reserved.
target database Password:
connected to target database: orcl (not mounted)
RMAN> restore controlfile from 'D:\oracle\product\10.2.0\oradata\orcl\CONTROL01.
CTL';
Starting restore at 28-AUG-09
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=156 devtype=DISK
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of restore command at 08/28/2009 01:14:40
ORA-19504: failed to create file "+DATA"
ORA-17502: ksfdcre:4 Failed to create file +DATA
ORA-15001: diskgroup "DATA" does not exist or is not mounted
ORA-15077: could not locate ASM instance serving a required diskgroup
ORA-19600: input file is control file (D:\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL\CO
NTROL01.CTL)
ORA-19601: output file is control file (+DATA)
RMAN>
according to me i guess i have not specified the disk group ="+data" properly or there is some other way to specify....
please can any help me resolving this problem
Thanks & Regards
