Running Oracle 11GR2 instance (non-ASM). Plan to set it up again from the scratch(this time using ASM, Grid infrastructure). And I need the present database.
I am thinking of the simple plan: 1) Backup using RMAN the existing instance. 2) Deinstall the existing instance. 3) Install Grid. 4) Install Oracle DB software. (Same version) 5) Restore RMAN backup.
Is this how I should proceed, or is there any other plan of action I can look to.
