Oracle database can be upgraded directly to the new release from the following releases:
- 11.2.0.4
- 12.1.0.2
- 12.2.0.1
- 18
If your current Oracle Database is a release earlier than 11.2.0.4, then you cannot directly upgrade your Oracle Database
to the latest release. In this case, you are required to upgrade to an intermediate release before upgrading to
Oracle Database 19c.
