Downgrading Oracle Grid Infrastructure Using Online Abort Upgrade
If upgrade of Oracle Grid Infrastructure fails before setting the active version of Oracle Clusterware, then follow these steps to downgrade Oracle Grid Infrastructure to the earlier release.
Run this procedure to downgrade Oracle Clusterware only when the upgrade
fails before root script runs the
crsctl set crs activeversion
command on the
last node. Use this procedure for downgrading Oracle Grid Infrastructure if there is a need to
avoid downtime of the whole cluster. This procedure downgrades the cluster to the previous
release. Because Oracle ASM and database operations are limited in this state, it is required
to downgrade the cluster as soon as possible. Complete the downgrade of Oracle Grid
Infrastructure as per the procedure documented in Downgrading Oracle Grid
Infrastructure after Upgrade Fails.
