Upgrading Oracle 11g(11.2.0.4) RAC to Oracle 19c(19.3) RAC on RHEL

in Database Install/Upgrade/Opatch (MOSC) 18 commentsAnswered

Hi,

Our customer's critical 24x7 production database runs on Oracle 11gR2 (11.2.0.4) RAC on RHEL 7.x

Customer has installed Oracle 19c(19.3) RAC on a New RHEL Servers.

The database size is around 1TB.

We have to migrate/upgrade to Oracle 19c (19.3) RAC with least downtime.

I am exploring various options to upgrade. I came across the method using Logical Standby Database.

If anyone of you have done a production database upgrade using this method/approach kindly share some details and links to some docs.

Regards,

Howdy, Stranger!
