See Duplicating a Database to ASM Storage and
RMAN DUPLICATE DATABASE From File System to ASM: Example
Hemant K Chitale
The procedure is almost the same with RMAN, I think the main difference is the Diskgroup name for the location of your DB files.
There are a lot of web pages with this information (RMAN from NonASM to ASM):
You have three main options:
- RMAN Active clonation (online without backup)
- RMAN Backup clonatio (with RMAN backup)
- EXPDP, your database is not very big, so you can use EXPDP to export and import your database.
If you don't have experience with RMAN clonation I would recommend you the third option.
I hope this help you.
