SQL Server Express is also known as Microsoft SQL Server Express, Microsoft SQLExpress, SQL Express, SQLExpress (related files: mdf, ldf, bak).

Making migration easy for you

Full Convert is a fully self-tuning software. Your migration will work as expected without you needing to adjust anything.

Data types are different in MariaDB compared to SQL Server Express. We automatically adjust them as we copy the tables so you don't have to worry about it. You can adjust the mapping rules if you wish to change the following defaults:

  • char text (if precision > 255)
  • datetime2 datetime (if version earlier than 5.6)
  • datetime2 datetime
  • datetimeoffset timestamp
  • geography longtext
  • geometry longtext
  • hierarchyid varchar(255)
  • image longblob
  • money decimal(19,4)
  • nchar text (if precision > 255)
  • ntext longtext
  • nvarchar text (if precision > 255 and version earlier than 5)
  • nvarchar text (if precision > 16383 and version at least 5)
  • nvarchar(max) longtext
  • smalldatetime datetime (if version earlier than 5.6)
  • smalldatetime datetime
  • smallmoney decimal(19,4)
  • text longtext
  • timestamp longblob
  • tinyint tinyint unsigned
  • uniqueidentifier binary(16)
  • varbinary longblob
  • varbinary(max) longblob
  • varchar text (if precision > 255 and version earlier than 5)
  • varchar text (if precision > 16383 and version at least 5)
  • varchar(max) longtext
  • xml longtext

Full Convert migration in 4 easy steps

SQL Server Express connection

SQL Server Express

We will choose SQL Server from the list of available source database engines. Depending on your SQL Server setup, you will need to connect using Windows or SQL Server authentication.

For SQL Express, we need to specify the server\instance name, like this: servername\SQLEXPRESS

We have Windows authentication here, so all we need to do is select our desired database from the drop-down list.



We will choose MariaDB from the source database engines list. As our MariaDB server is on the local machine and we have full privileges, we will simply choose a database from the dropdown menu.

MariaDB connection

Start the conversion

All source tables are selected for conversion by default. In case you only need some tables, simply deselect the ones you don't need - or deselect all, then select just the tables you do need. Click the Copy your database button to get started.



Conversion is highly-optimized to run as fast as possible, yet provides top-notch reliability. Huge tables are converted in small chunks at a time, preserving memory and ensuring that your computer stays fast and responsive.
