Mixed version Data guard setup

Hi All,

Am Sachin part of Oracle ACS.

We are in process to migrate the Databases from one DC to other DC.

While migrating the DC we are also proposing to upgrade the Database version.

Currently maximum database version is 12.1.0.2 and we are proposed to have upgrade version as 12.2.* or 19c.

Is it possible to configure Physical standby with mixed version as below.

Primary Database version 12.1.0.2 and physical Standby Database version 12.2.* or 19c maintaining the Compatible to 12.1.0.2 on both primary and standby.

Is there any challenge which may be faced during switchover and open database in read-write mode, with above mixed version setup.

Howdy, Stranger!
