Re: 10204 RAC upgrade

You can do rolling patching for Clusterware. For Database and ASM, you can install 10.2.0.1 +10.2.0.4 patch in different home directly. Bring down database and start one instance and run catupgrd.sql

Then bring down db again and using srvctl change the ORACLE_HOME in OCR using srvctl command. You will also be required to copy the init*ora and password files in new Oracle home. I think this should fit into your 2-3 hrs window

But test this :)
