I have a 2-node RAC 11.2.0.2 running on 64-bit Red Hat Linux. Documentation 
says we can't do in-place upgrade of the grid infrastructure, and we don't want 
to do out-of-place upgrade. So the only option is to deinstall 11.2.0.2 and 
reinstall 11.2.0.3. Can the new grid infrastructure work with the existing 
11.2.0.2 database (which can be upgraded later)? If you know the page in the 
documentation, please share the URL. Thank you.

Downtime is not an issue. We can also extract ASM metadata with md_backup 
command inside asmcmd. But we don't know the data it creates can be restored by 
md_restore of the newly installed grid.
