Moving from 32bit to 64bit

edited Oct 23, 2009 6:52AM in Database Administration (MOSC) 4 commentsAnswered
I am moving 3 instances from a 10.2.0.3 32-bit to 10.2.0.4 64-bit (Linux).   These are on two different hosts, I am wondering what is the easiest way to move these instances.
- Are the datafiles compatible where I could just move them over and do a regular patch upgrade? 

- Can I do a rman backup and duplicate to the new database?

I would rather avoid the export/import method, but I am wondering if that is the only way.

Howdy, Stranger!
