Migrating to ASM on new hardware via RMAN

Slightly related to my previous post, but I thought it deserved its own thread.

To recap, I'm migrating my 10g (10.2.0.2) instance from a 32-bit machine to a shiny new 64-bit monster, obviously doing this on test instances first. We currently use non-ASM storage on linux filesystems. As part of the migration, we wanted to make the change to ASM. I had been reading an Oracle HOWTO [1] but it seems to address migrating from non-ASM to ASM on the same instance on the same box.

I'm wondering if it is feasible to use RMAN to duplicate the current production instance onto my 64-bit machine using the DUPLICATE DATABASE command, and using db_file_name_convert and log_file_name_convert to specify the ASM disk group as the new destination.

My alternative method is to create a brand new 64-bit instance and use datapump to move the application schemas over. I'd still have to create all of the users/roles though and set privileges again, but I have some scripts to create those statements (from previous HP-UX -> Linux migration).
