Overview of the Upgrade Procedure

Learn about the prerequisites of performing an upgrade for Oracle GoldenGate.

For Microservices, the earliest version that can be upgraded from is Oracle GoldenGate 12c (12.3.0.1). As a best practice, perform a minimal upgrade first, so that you can troubleshoot more easily in the event that any problems arise. Once you know your environment is upgraded successfully, you can implement the new functionality.

The upgrade instructions also include the steps for upgrading the source or target database and Oracle GoldenGate at the same time. Following are the pre-upgrade requirements:

• Stop all Oracle GoldenGate processes.

• Upgrade the database and then start it.

• Start Oracle GoldenGate.

• Disable the DDL trigger if there is no native DDL support.
