Oracle Database Rolling Upgrade
Hi,
We have 4 node RAC in production with 11.2.0.4 version. This production environment has two standby environments
a - single instance ACTIVE DATAGUARD (non-RAC).
b- 2 node PHYSICAL STANDBY (RAC).
We are planning to upgrade all these environments in ROLLING upgrade fashion. You are requested to share the docs and steps required to be performed.
Regards,
Taoqir
