Restoring SQL Server 2000 database to SQL Server 2008 Is it necessary to restore system databases of SQL Server 2000 to SQL Server 2008, if I am restoring my other databases from 2000 to 2008?
No. In fact you can't restore the system databases from a SQL Server 2000 system to a SQL Server 2008 instance. If you did parts of (or the entire) database engine won't work as the SQL Server 2000 system databases are formatted very differently from SQL Server 2008.
