When you supply the project with the new dlls and replace them, they automatically upgrade your configs and your database. If you wonder if your database has been successfully upgraded, you can find the version of the database in the table [sf_schema_vrsns] where there is a column [version_number] which holds the actual project version.
Also the upgrade logs can be found in the same folder as the original error logs - yourproject/App_Data\Sitefinity/Logs
but their name starts with UpgradeTrace
