Clustered ASM instances for 11g onwards can be upgraded using a rolling upgrade.
I want to upgrade the asm version from 220.127.116.11 to 18.104.22.168
Ones node rolling migration is enabled you can be shutdown, upgraded and started.
Do not perform following operation when asm is in rolling migration mode:
- Mount and dismount of the disk groups.
- Open, close, resize, and delete of database files.
- Access to local fixed views and fixed packages.
The current status of the ASM cluster can be determined using the following query.
After upgradation on all nodes. you can stop the rolling migration
