I understand an upgrade from Confluence 5.6.6 to Confluence 6.2 failed with the following error:

```
2017-12-22 20:01:48,166 ERROR [localhost-startStop-1] [atlassian.confluence.plugin.PluginFrameworkContextListener] error Upgrade failed, application will not start: com.atlassian.config.ConfigurationException: Cannot update schema

Caused by: org.hibernate.tool.schema.extract.spi.SchemaExtractionException: More than one table found in namespace (, ) : cwd_app_dir_group_mapping
```

(The WARN level errors you included are benign per [c3p0 Class not Found on the Classpath and its Properties are Ignored](https://jira.atlassian.com/browse/CONFSERVER-52296))

If you are using an Oracle database, that error can be caused by the Oracle user having the select any table permission, or if the local all objects view is not set up as in this article: [Step 3. Set up your Oracle user with schema-creation privileges](https://confluence.atlassian.com/conf62/database-setup-for-oracle-902074978.html#DatabaseSetupforOracle-Step3.SetupyourOracleuserwithschema-creationprivileges)

If you are not using an Oracle database, please let me know what database you are using. If the Oracle user was already set up as in the article I linked, please let me know that as well.

Thanks,

Ann
