SQL Servers allow the import or export of database diagrams to another database. All the information related to a database is stored in the dtproperties table. Therefore, to import or export a database, the dtproperties table will have to be imported or exported too. The database which contains a transfer scheme can be used to export to another database. Configuration is done automatically in the source database but has to be done manually in the destination database. To transfer the data from one database to another, the 'select all tables and view sources' option must be used to transfer to the dtproperties table in the destination column.
