How do you migrate oracle database from Non ASM to ASM

 In this tutorial i will explained step by step  Migration from non asm oracle database to asm oracle database 

Simple Steps of database migration From Non ASM to ASM::
  1. SET THE control_files and db_create_file_dest
  2. backup the database and archivelog with controlfile using rman utility
  3. SET THE control_files and db_create_file_dest to relevent asm disk
  4. shutdown the database
  5. startup the nomount mode and Restore the control file
  6. mount the database
  7. Backup Database Into Asm Disk Group
  8. Switch All Data Files To The New Asm Diskgroup Location
  9. recover the database
  10. open the database using resetlogs
STEP 1. SET THE control_files and db_create_file_dest PARAMETER BEFORE BACKUP IF NOT SET  IN NON ASM DATABASE AND ALSO ENABLE ARCHIVELOG MODE
SQL>
alter system set control_files='/home/oracle/kfc/oradata/control/control01.ctl' scope=spfile;
alter system set db_create_file_dest='/home/oracle/kfc/oradata/data/' scope=spfile;
--The ALTER DATABASE ARCHIVELOG command can only be performed if the database in mounted  mode.
alter database close;
alter database archivelog;
-- BACKUP THE UPDATED pfile 
create spfile from pfile;
create pfile from spfile;
startup force;
--CHECK THE control_files and db_create_file_dest PARAMETER IF ENABLED OR NOT
SQL>  sho parameter db_create_file_dest 
SQL>  sho parameter control_files

STEP 2. BACKUP THE DATABASE WITH ARCHIVELOG  USING RAMAN BEFORE  TAKING BACKUP ENABLE THE CONTROLFILE AUTOBACKUP ON
RMAN>
rman target /
CONFIGURE CONTROLFILE AUTOBACKUP on;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/home/oracle/rman_control/%F';
backup database plus archivelog format '/home/oracle/rman_data/data_%U';
STEP 3.SET THE DB_control_files and db_create_file_dest PARAMETERS TO THE  RELEVENT ASM DISK GROUPS. 
alter system set control_files='+DG1' scope=spfile;
alter system set db_create_file_dest='+DG1' scope=spfile;
STEP 4.SHUT DOWN THE TARGET DATABASE AND STARTUP THE DATABASE UNTIL NOMOUNT STAGE THEN CONNECT TO RMAN UTILITY
shut immediate;
startup nomount;
create pfile from spfile;

SQL> show parameter control

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
control_file_record_keep_time        integer     7
control_files                        string      /home/oracle/kfc/oradata/contr
                                                 ol/control01.ctl

[oracle@teng dbs]$ rman target /
Recovery Manager: Release 10.2.0.1.0 - Production on Thu Jul 28 09:14:08 2016
Copyright (c) 1982, 2005, Oracle.  All rights reserved.
connected to target database: kfc (not mounted)
STEP 5. RESTORE THE CONTROLFILE FROM RMAN CONTROL FILE BACKUP LOCATION('/home/oracle/rman_control/%F';)
RMAN> restore controlfile from '/home/oracle/rman_control/c-1039361779-20160803-00';

Starting restore at 03-AUG-16
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=35 devtype=DISK

channel ORA_DISK_1: restoring control file
channel ORA_DISK_1: restore complete, elapsed time: 00:00:17
output filename=+DG1/kfc/controlfile/current.283.918908975
Finished restore at 03-AUG-16
STEP 6. MOUNT THE DATABASE USING RESTORED CONTROLFILE(DATABASE WOULD NOT BE MOUNT IF NO CONTROLFILE)
RMAN> alter database mount;
database mounted
released channel: ORA_DISK_1
STEP 7.BACKUP DATABASE INTO ASM DISK GROUP ('+DG1')
RMAN>backup as copy database format '+DG1';
Starting backup at 03-AUG-16
using channel ORA_DISK_1
channel ORA_DISK_1: starting datafile copy
input datafile fno=00001 name=/home/oracle/dummy/0rrbqn03.dbf
output filename=+DG1/kfc/datafile/system.284.918909681 tag=TAG20160803T124120 recid=10 stamp=918909765

channel ORA_DISK_1: datafile copy complete, elapsed time: 00:00:26
Finished backup at 03-AUG-16

RMAN-06497: WARNING: control file is not current, control file autobackup skipped
STEP 8.SWITCH ALL DATA FILES TO THE NEW ASM DISKGROUP LOCATION ('+DG1').
RMAN> switch database to copy;
datafile 1 switched to datafile copy "+DG1/kfc/datafile/system.284.918909681"
datafile 2 switched to datafile copy "+DG1/kfc/datafile/sysaux.285.918909767"
datafile 3 switched to datafile copy "+DG1/kfc/datafile/tbs.286.918909847"
datafile 4 switched to datafile copy "+DG1/kfc/datafile/tbs1.287.918909885"
STEP 9.RECOVER THE ORACLE DATABASE USING "recover database" COMMAND
RMAN> recover database;
Starting recover at 03-AUG-16
using channel ORA_DISK_1
starting media recovery
archive log thread 1 sequence 4 is already on disk as file +DG1/kfc/onlinelog/group_1.277.918365371
archive log filename=+DG1/kfc/onlinelog/group_1.277.918365371 thread=1 sequence=4
media recovery complete, elapsed time: 00:00:01
Finished recover at 03-AUG-16

STEP 10.OPEN DATABASE USING RESETLOGS
RMAN> alter database open resetlogs;
database opened
STEP 11.CHECK THE DATABASE DATAFILE AND CONTROLFILE LOCATION WHETHER IS SUCCEFULLY RESTORED OR NOT IN  ASM DISK.
SQL> show parameter control;

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
control_file_record_keep_time        integer     7
control_files                        string      +DG1/kfc/controlfile/current.2
                                                 83.918908975
SQL> show parameter db_create

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
db_create_file_dest                  string      +DG1
