原因

When using the installer, the JDBC driver didn't get copied into the new WEB-INF/lib directory.

Oracle is a special case as we don't bundle Oracle drivers and that's the reason it is not in WEB-INF/lib. During the upgrade the installer did not move over any added files to the new installation and in case of Oracle it would mean that Confluence wouldn't be able to connect to a database.

ソリューション

Copy the jdbc from your old installation to your new installation, or download the latest driver from the manufacturer's website. The JDBC driver needs to be copied into <confluence-install>/confluence/WEB-INF/lib folder. Please check Database Setup for Oracle for database & driver compatibility.
