We're going to be doing an 11g upgrade and I'm wondering what steps are required to convert 10g ASM managed raw devices to 11g ASM managed raw devices (see scenario below): 4 QA databases in 10g on serverA
- Each QA database has its own disk group in 10g ASM

If I build an 11g ASM instance on serverB and SAN replicate the raw devices to the same raw device names on serverB (matching serverA), how do I make sure the 11g ASM instance is properly managing these devices from 10g - are there scripts that have to be run? In a case where ASM is being used to manage multiple databases and multiple disk groups, do all diskgroups from 10g have to be moved to 11g at once, or can I piece-meal them over to the 11g server?

Any other thoughts/concerns/suggestions?

Thanks
