Hi,

We are planning to upgrade our RAC (including GI and DB home) from 11.2.0.3.x to 11.2.0.4.x (with lastet PSU patch).  Below are our current RAC database details

OS details :
Linux 2.6.18-371.11.1.el5 #1 SMP - x86_64 x86_64 x86_64 GNU/Linux

GI Home details :
  Grid Infrastructure Patch Set Update : 11.2.0.3.9
  ASM version : 11.2.0.3.0

Database Home details :
Database Patch Set Update : 11.2.0.3.9 (17540582)
database version : PSU 11.2.0.3.9

Since we have 10 11.2.0.3 RAC databases are running with seperate ORACLE_HOME under this GI (CRS), we would like to upgrade these databases with miminal downtime window.  Please share the best practices to achive this database upgrade.

Please review the below steps and suggest : Can we Install 11.2.0.4 RAC software before GI upgrade and Can we make use this installation during our GI upgrade.

Howdy, Stranger!
