Overall performance of the export import process depends on the resources involved in the process. UniversalAuthentication:False /TargetUser:******* /TargetPassword:******* TargetServerName:******* /TargetDatabaseName:AdventureWorks2019_w10lt_s UniversalAuthentication:False /SourceUser:******* /SourcePassword:*******Ĭ:\Program Files\Microsoft SQL Server\150\DAC\bin>SqlPackage.exe /Action:Import /SourceFile:F:/DBs/AdventureWorks2019_w10lt_s.BACPAC Here is an example of that process.Ĭ:\Program Files\Microsoft SQL Server\150\DAC\bin>SqlPackage.exe /Action:Export /TargetFile:F:\DBs\AdventureWorks2019_w10lt_s.BACPAC Once you install it on a client machine you will be able to run commands to export a BACPAC from Managed Instance, and then to import it into a SQL Server. SqlPackage utility can be downloaded from here. The utility also offers more parameters than SSMS, so it offers more flexibility and options for fine-tuning. If you need to migrate more databases, using a command line tool might be more convenient than SSMS. Performing BACPAC export/import via SqlPackage utility In SSMS, connect to the target SQL Server and you will find the database with schema and data. The final step will show the operation progress and once it reaches Operation Complete the database will be ready. On Database Settings window, set the New database name. On the Import Settings window click Connect, connect to your Azure account, then select Container and File name of the BACPAC previously saved and click Next. Now, connect to the target SQL Server and from the Databases context menu choose Import Data-tier Application. When it reaches Operation Complete, your BACPAC will be saved in the Azure Storage account. The final step will show the operation progress. In Export settings, click Connect, connect with your Azure account, then choose target Container and File name and click Next.įollow through the Wizard. In SSMS, from the context menu of a database you want to migrate choose Tasks, Export Data-tier Application. To migrate the database, we will export a BACPAC to Azure Storage (other options are available as well) and then import it from Azure Storage to a SQL Server. Let’s quickly go through the steps in SSMS. The process is covered in the documentation. The second step is creating a user database on SQL Server by importing created BACPAC. The export process is explained in the Azure documentation. That can be done from variety of tools: Azure Portal, SqlPackage command line utility, SSMS, Azure Data Studio or PowerShell. To migrate user database from Managed Instance to SQL Server, first you would need to export the database to a BACPAC file. Performing export/import via SSMS and BACPAC You will find more details about this later in Transactional consistency paragraph. In other words, BACPAC does not guarantee transactional consistency. Note: With BACPACs, data consistency is guaranteed only at the point of execution against each individual database object, meaning that inflight transactions are missed. However, in a situation where it’s not possible to use a database backup, BACPAC may be an acceptable substitute. Although BACPAC file contains data and metadata and can be used to deploy a copy of the source database, it is not a backup and shouldn’t be considered as such. A BACPAC file can be exported to Azure Blob storage or to local file system in an on-premises location and later imported into SQL Server or Azure SQL Managed Instance, or Azure SQL Database. For more information you can refer to Data-tier Applications - SQL Server | Microsoft Docs. BACPAC is a ZIP file with an extension of BACPAC, containing both the metadata and data from SQL Server database.
