Prerequisites

Learn about prerequisites for upgrading Oracle GoldenGate Microservices Architecture.

As a best practice, perform a minimal or basic upgrade first, which implies performing the upgrade without adding any new features and additional or non-mandatory parameters.

If Oracle GoldenGate is upgraded at the source side where the Extract exists, then the trail file format remains the same. Only if a higher FORMAT RELEASE is adjusted to the EXTTRAIL parameter or an ETROLLOVER is performed, will the trail file get upgraded to a higher release. This provides the opportunity to upgrade the target system where the Replicat exists, independently. When all target systems are upgraded, you may update the format release of the EXTTRAIL parameter to leverage new features that rely on a higher trail file format. No repositioning of any process is required.

After you verify that the environment is upgraded successfully, you can implement the new features and additional parameters as required.

The upgrade instructions also include the steps for upgrading the source or target database and Oracle GoldenGate at the same time.
