Domain.com wants to migrate the CK_Data database to SQL Server 2005. You install a new SQL Server 2005 database server named Certkiller -DB02. You want to create a new database named CK_Data and all the required tables on Certkiller -DB02. You must import the data into the CK_Data database on Certkiller -DB02.
