Upgrade of Oracle GI to Oracle Steps

Just noting down the high level steps which were performed for the Upgrade of Oracle GI to Oracle on RHEL 64bit Linux.

Create a backup of 11G GI HOME as root user:

. oraenv <<< +ASM
 sudo su -
cd /oracle/backup
tar -cvf backup_GI.tar /u01/grid/product/
tar -cvf backup_inventory.tar  /var/opt/ora/oraInventory/

Stop all DB instances and listener

run the GI 12c runInstaller in silent mode using UPGRADE option in the response file.

Run the script as root user.

check the HAS version and oratab

crsctl query has releaseversion
cat /etc/oratab

Start the listener and DB instances

Cleanup Backup files (can be executed few days later)

Hope that helps.
