How to Copy SQL Server Databases from Windows to Linux

Now that Microsoft has released SQL Server for Linux, even if your main tech stack is tied to a Windows Server you may want to copy the database to another SQL Server located on a Linux computer.

There are a few ways to tackle this task. This article examines the following methods to copy the SQL Server database from Windows to Linux:

  2. Generation of T-SQL database script (such as mysqldump)
  3. Creating BACPAC
  4. SqlBak service
