Oracle RAC 12C Rolling Upgrade

in Database Install/Upgrade/Opatch (MOSC) 12 comments

Hi,

We have 2 node RAC primary and 2 node RAC standby in production with 12.2.0.1 version, and data guard is setup for data replication. OS for the 4 nodes is AIX 7.1.

We are planning to upgrade from 12C to 19C in ROLLING upgrade fashion (i.e. no zero downtime). Could you please share the docs and steps required to be performed? Thank you.


Regards,

Stephen
