Note that the Import from Azure option also requires that you specify a local directory for the temporary file. You must connect to a Microsoft Azure container to validate this option.

In Object Explorer, right-click on Databases, and then select the Import Data-tier Application menu item to launch the wizard. To launch the wizard, use the following steps:Ĭonnect to the instance of SQL Server, whether on-premises or in SQL Database. Using the Import Data-tier Application Wizard Importing a DAC without logins to SQL Database requires membership in the dbmanager or serveradmin roles. Importing a DAC with logins to SQL Database requires membership in the loginmanager or serveradmin roles. The built-in SQL Server system administrator account named sa can also import a DAC. PermissionsĪ DAC can only be imported by members of the sysadmin or serveradmin fixed server roles, or by logins that are in the dbcreator fixed server role and have ALTER ANY LOGIN permissions. This is not needed for Windows Authentication logins because their passwords are not managed by SQL Server. To enable the logins, sign in using a login that has ALTER ANY LOGIN permission and use ALTER LOGIN to enable the login and assign a new password that can be communicated to the user. When the file is imported, the login is created as a disabled login with a generated password. To improve security, SQL Server Authentication logins are stored in a DAC export file without a password. For more information about how to perform these checks, see Validate a DAC Package. Before you use an export file from an unknown or untrusted source, unpack the DAC and examine the code, like stored procedures and other user-defined code. Such files could contain malicious code that might execute unintended Transact-SQL code or cause errors by modifying the schema. We recommend that you do not import a DAC export file from unknown or untrusted sources. You cannot deploy those DACs to instances of SQL Server 2005 (9.x). If you export a DAC from a higher version, the DAC may contain objects not supported by SQL Server 2005 (9.x). ![]() Limitations and restrictionsĪ DAC can be imported to SQL Database, or an instance of the Database Engine running SQL Server 2005 (9.x) Service Pack 4 (SP4) or later. After the import completes, you can use the ALTER DATABASE statement, SQL Server Management Studio, or SQL Server PowerShell to tailor the database. Physical properties, such as the number of filegroups, or the numbers and sizes of files cannot be altered as part of the import process. Some database options, such as TRUSTWORTHY, DB_CHAINING, and HONOR_BROKER_PRIORITY, cannot be adjusted as part of the import process. A DAC export file uses the values from the original database. Database Options and Settingsīy default, the database created during the import will have all of the default settings from the CREATE DATABASE statement, except that the database collation and compatibility level are set to the values defined in the DAC export file. The DAC will then be present in the Deployed Data-tier Applications node of the Management Studio Utility Explorer and reported in the Deployed Data-tier Applications details page. If you import a DAC to an instance of the Database Engine, the imported DAC is incorporated into the SQL Server Utility the next time the utility collection set is sent from the instance to the utility control point. The import bulk copies in the data from the export file. The import creates a new DAC and associated database using the DAC definition stored in the export file, the same way a DAC deploy creates a new DAC from the definition in a DAC package file. The import process builds a new DAC in two stages. ![]() Export-import operations can be combined to migrate a DAC or database between instances, or to create a logical backup, such as creating an on-premises copy of a database deployed in SQL Database. bacpac file - to create a copy of the original database, with the data, on a new instance of the Database Engine, or to Azure SQL Database.
