Content Server Database Change

When the Content Server starts the first time after upgrading from version 2004 or 2007, it will automatically adapt database tables and remove existing unique constraints for the versionUuid_ column of all document type tables. For Microsoft SQL Server and IBM DB2, and when upgrading from 2007.1, wrong unique constraints are also removed from the uuid column of tables CmUsers and CmGroups .

The constraints are replaced with plain database indices. The database constraints were originally introduced with 2004.1 and 2007.1 but are not helpful and can cause problems. This also fixes a bug for SQL Server and DB2 databases, that the Content Server is unable to import an Active Directory user, if the user account has been disabled and re-enabled again in Active Directory.

Note, that it is not possible to start a Content Server of a previous release on the database after the new Content Server has adapted the database tables. You should always make a backup of the Content Server database before upgrading. This is even more important for this change.
