Thanks to all who replied. I am reading the following documentation. http://docs.oracle.com/cd/E11882_01/server.112/e23633/upgrade.htm It has lots of information about upgrading the DB, but seems to be limited on clusterware/ASM upgrade. It just instructs to install clusterware in a new home. Is anyone aware of any metalink document?
