1. Check the current status and all the files (datafiles, controlfiles, logfiles) information.

2. TAKE A BACKUP of current ASM database (Make sure Controlfile backup is on)
[oracle@rac1 ~]$ rman target /

new RMAN configuration parameters:

3. Change parameter and Create pfile for NON ASM database
RMAN> alter system set db_file_name_convert=' +DATA/TESTP/DATAFILE/',' /u01/app/oracle/oradata/TESTP'
scope=spfile;
using target database control file instead of recovery catalog
Statement processed
RMAN> alter system set log_file_name_convert=' +FRA/TESTP/ONLINELOG/',' /u01/app/oracle/oradata/TESTP'

Statement processed
RMAN> select value from v$parameter where name='spfile';
VALUE
-------------------------------------------------------------------------------+DATA/TESTP/spfile
RMAN> create pfile from spfile;
Statement processed

3. 4. Change the parameters for NON ASM and create the required directories for database
*.audit_file_dest='/u01/app/oracle/admin/TESTP/adump'
*.core_dump_dest='/u01/app/oracle/admin/TESTP/cdump'
*.audit_trail='db'
*.compatible='12.1.0.0.0'
*.control_files='/u01/app/oracle/oradata/TESTP/testp.ctl'#Restore Controlfile
5. Startup database at nomount
RMAN> shutdown immediate;
database closed
database dismounted
Oracle instance shut down
RMAN> startup nomount pfile='/u01/app/oracle/product/12.1.0/dbhome_1/dbs/initTESTP.ora';

So datafiles have been moved to ASM to NON-ASM database.
Rename Datafiles
==============
NOTE: I am not using set newname as I am going to use 12c "move" command
Connect target /
Run
{
allocate channel tape1 device type sbt;
set newname for datafile 1 to '/../system_01.dbf' ;
set newname for datafile 2 to '............'
.........
set newname for datafile 4 to '...........'
