Closed, Fixed and tested
A database that is not converted to UTC throws an exception. Conversion can be done before upgrading.
Previous versions had no knowledge about which time zone is stored in the database, so required manual intervention.
See this SDK article for details: http://world.episerver.com/documentation/developer-guides/CMS/Deployment/storing-utc-date-and-time-in-the-database/
