If it would have delete complex data sets, this would be a disaster!Daniel Gheczy2013-12-11T12:25:00ZRE: Installation of a new version deletes all privious entriesTobias Schmitthttps://www.klaros-testmanagement.com/en/c/message_boards/find_message?p_l_id=11703&messageId=292222013-12-11T12:25:00Z2013-12-11T12:25:00ZHi Daniel,<br /><br />we have tried to reproduce your update problem on two different machines using an existing derby database and have not experienced any problems. Can you please provide some more information about your system (e.g. Operating system, java version, etc) and send us your tomcat logfiles to support@verit.de? It would be of great help to us if you send us your whole klaros home folder too, so we can have a look to the hibernate properties and the database to see what's wrong. <br /><br />To use klaros in a production environment we definitly recommend to use a full grown database like MySQL or PostgreSQL and of course do regular backup. <a href="http://www.klaros-testmanagement.com/wiki/-/wiki/Klaros/FrequentlyAskedQuestions#section-FrequentlyAskedQuestions-DerbyFileAccessIsSlowIsItPossibleToUseAFullBlownSQLDatabaseServer">FAQ</a><br /><br />Regards,<br /><br />TobiasTobias Schmitt2013-12-11T12:25:00Z
