I have an existing 2 node Oracle 10.2.0.5 RAC Setup. I have a requirement wherein I have to upgrade the RAC setup to 11R2. I have upgraded the CRS to Grid and successfully installed Oracle 11g Oracle DB software. I have ASM instance running from my 10.2.0.5 Oracle DB Home. Kindly suggest how do i go about upgrading the ASM instance and the database. Kindly mention any MOS docs for reference(i tried to search but was not able to find a suitable doc).
