There is a bug by the upgrade from 1.5.3 to 1.6 beta. After no replay from the developer team here:
http://forums.opengoo.org/index.php?topic=3044.0 I post the bug here again:
First I installed 1.5.3 and import my database backup. Then I installed 1.6 beta and made the upgrade.
I do the upgrade manually and I got the following message by the upgrade:
Config file found and loaded. File '/config/config.php' exists and is writable Folder '/config' exists and is writable Folder '/cache' exists and is writable Folder '/tmp' exists and is writable Folder '/upload' exists and is writable Extension 'mysql' is loaded Extension 'gd' is loaded Extension 'simplexml' is loaded Upgrade script has connected to the database. Test query has been executed. Its safe to proceed with database migration. Database schema transformations executed (total queries: 30)

The upgrade process is not successful. The file installed_version is not changed to 1.6-beta.
When you looked in to OpenGoo 1.6 beta you have only the Overview.
