This Document shows the step by step of upgrading database from 10gR2 RAC to 11gR2 RAC. I have chosen the below upgrade path which will allow me to upgrade 10gR2 Clusterware and ASM to 11gR2 Grid infrastructure. In this upgrade Path, the original 10gR2 CRS installation was made hidden as if there is no CRS existed. Then, the fresh installation of 11gR2 Grid Infrastructure was taken place and 10gR2 ASM diskgroups were moved and mounted using the new 11gR2 Grid HOME. At this stage, the original 10gR2 RAC database was managed by 11gR2 Grid HOME. At the end, the 11gR2 RAC database home was installed and the original 10gR2 RAC database was upgraded to 11gR2 RAC manually.
