⭐ Key Features

Accurate Schema Conversion

Convert tables, primary keys, indexes, views, and foreign keys — with full control over what to migrate. Tools migrate entire database schemas ensuring complete schema integrity.

Smart Data Type Mapping

Handles complex conversions automatically: UNIQUEIDENTIFIER→CHAR(36), MONEY→DECIMAL(19,4), BIT→TINYINT(1), DATETIME2→DATETIME, NVARCHAR(MAX)→LONGTEXT. Automatic mapping with manual override options for perfect compatibility.

Trigger-Based Syncing (DBSync only)

Real-time synchronization using lightweight triggers without requiring SQL Server CDC.

Flexible Filtering Options

Migrate the entire database or selected objects only. Create custom rules to migrate specific tables, rows, or columns.

Fast Parallel Migration Engine

Multi-threaded data transfer with efficient table data processing. Combine data from multiple sources when needed.

Using SQL Server to MySQL Tools

When launching the DBConvert or DBSync application in GUI mode, it seamlessly guides you through the steps to initiate database migration or synchronization:

1

Connect to SQL Server source database

Specify the username/password and host/port parameters if your source database requires login credentials.

Connect to SQL Server source database from DBConvert
2

Connect to MySQL destination database

Specify parameters for the destination database similar to the source, defining connection settings and username/password pairs.

Connect to MySQL target database from DBConvert

NOTE #1

Each DBConvert or DBSync tool's name comprises two different databases, enabling any specified database to operate as the source or destination. Furthermore, the same type of database can function as both the source and destination.

NOTE #2

Connections to cloud databases (e.g., Amazon RDS, Google Cloud, or Azure SQL) aren't explicitly specified in the user interface but use the same settings as traditional on-premises databases.

NOTE #3

Connections to source and target databases remain active until you close the DBConvert/DBSync application or reopen new connections.

Refer to our documentation for specific source/ destination configurations for different databases.

3

Configure database migration options

Specify the tables, fields, indices, and views you want to transfer to the MySQL destination database by checking/unchecking the corresponding boxes.

Customize general database/ tables settings. Or configure specific table, field, index object individually when migrating data.

Explore our articles in the user's manual about Configuring database migration options for detailed information.

4

Detection of potential database migration issues

The database enforces certain relations on the data, and on the customization step, an intelligent error checker verifies all possible data integrity and referential integrity issues. It highlights any problems before migration starts.

By default, DBConvert attempts to automatically map the database types of the source SQL Server database to the closest equivalent of the target MySQL database types. However, you can manually change the data types for the entire database globally using the "Global mapping" or individually for each field.

Explore the Intelligent error checker for more information on errors and warnings.

5

Execution - The final stage of data migration

Initiate the conversion or synchronization process after configuring source and destination databases in the previous steps.

Click the "Commit" button to start conversion. Here, you can also monitor the conversion/synchronization process.

Optionally save connection settings and configuration parameters into the session file to schedule the launching of sync or conversion jobs regularly.

DBConvert Software Features

Command line mode

Pass previously saved sessions as parameters to the Command-Line DBConvert Client. A session retains SQL Server source and MySQL target database connection settings with other specified options.

Example:

C:\Program Files\DBConvert\mssql2mysqlPro\mssql2mysqlPro_Cons.exe /Session:"Session_Name"

NOTE: First, run the software in GUI mode to create a session file with initial parameters.

Built-in scheduler

Our applications include a built-in scheduler to run database conversion and sync jobs at specified times. Set the scheduled date and time to execute job sessions automatically.

Find more Information about the built-in scheduler.

System Requirements

Ensure your system meets these requirements for optimal performance

Supported OS

Requirements

  • Necessary privileges to write into database on the target MySQL server (this requirement is optional as there is an option to overcome the restrictions using dump file or PHP Script)
  • Necessary privileges to write into database on the target SQL Server (this requirement is optional as there is an option to overcome the restrictions using dump file)
