Best approach of upgrade in a 2 node rac with 2 node standby databases

Hi All,

OS: RHEL 7

DB: 12.2.0.4

We are planning to upgrade our Grid and RDBMS from 12R2 to 19.7, we have 2 node RAC along with 2 Node physical standby.


We need to come up with the best way to upgrade this with minimum downtime.

Can we upgade the standby database first and then switchover to upgraded standby and then upgrade the Primary, is this possible?


Thanks
