In this article i would like to discuss couple of options we have in migrating Database storage to ASM (Automatic Storage Management). Recently we had a to migrate a moderately sized database to ASM storage and found migrating to ASM through enterprise manager was the Best Option, its was just few clicks and instance was migrated.

- Migrating using Enterprise Manager
- Migrating using Recovery Manager (RMAN)
- Migrating using Oracle DataGuard
With Enterprise Manager migration was pretty smooth, if you would like to try the RMAN approach then refer Metalink Note 312731.1 (section 3.8) for a step by step instructions on migrating
