MS Access to MySQL : Being an ideal option for personal database deployed on a laptop or desktop, MS Access can hardly be scaled up to use in high load concurrent access environments. It is not surprising that as the volume of data and the number of users grows, many organizations are thinking about migrating to a more powerful and reliable database management system.
On the other hand, migration between different DBMS is complicated and tedious procedure involving risks of data loss or corruption. It is reasonable to realize if you really need to move from MS Access to MySQL before arranging the database migration.

MySQL has many benefits toward to MS Access such as high level of security and the performance, tight integration with Web, scalability and cross-platforming. However, for the cases when just a few users access the database, data volume is low and no need for sophisticated security, the database migration will not give much benefits.
The ETL Model for MS Access to MySQL Migration:
Generic approach to MS Access to MySQL migration is usually implemented according to extract-transform-load method that includes the following steps:
- Definitions of MS Access tables, indexes and constraint are exported in form of CREATE-statements, converted to MySQL format, and then loaded to the target database.
- MS Access data is migrated to CSV files (one file per table) as intermediate storage, transformed according to MySQL requirements (focus on binary and date/time) and imported to previously created tables.
- Relationships between tables are extracted in form of CREATE-statements, converted into MySQL foreign keys and then imported to the target database.
- MS Access queries are exported in form of SQL statements, converted according to MySQL syntax and then recreated in the target database as views.
In order to eliminate risk of human errors, the database migration should not be done manually. There are miscellaneous options of automation based on either free or commercial tools. Free tools usually require more manual efforts on pre-processing or post-processing steps, while commercial products automate of the entire database migration.

Methods of Migration from MS Access to MySQL:
1. Manual Migration Using ODBC Driver:
As example of migration option that does not require any commercial software, you can export the tables directly from MS Access interface using ODBC driver or Connector for MySQL. Open MS Access, select table in the left pane, right click on the table name and select Export > ODBC Database item in the popup menu.
After a few more prompts the data will be migrated from MS Access to MySQL. Note that constraints, indexes and queries are not converted via this method. Also, it requires some setting up and post-processing efforts, therefore this option should be considered as semi-automated.
Another approach to this database migration is to use of dedicated commercial software. Key benefits:
- 100% automation
- Easy to use, no special skills are required
- Error free, smooth and safe database migration
One of the most popular tools implementing this approach is the MS Access to MySQL converter developed by Intelligent Converters. This software company provides solutions for database migration and synchronization across multiple DBMS such as PostgreSQL, MySQL, Oracle, SQL Server, SQLite, IBM DB2 and MS Access for more than 20 years.
MS Access to MySQL converter is easy-to-use tool with wizard-style intuitive user interface. It can achieve performance near to 10,000 rows per second on average modern platform due to low-level highly efficient techniques of reading and writing data. The program migrates all major database objects such as table definitions, data, constraints, indexes, relationships between tables and queries with respect to related properties and attributes.
Other features of MS Access to MySQL converter:
All versions of MS Access and MySQL are supported including forks (MariaDB and Percona) and popular SaaS platforms (Azure for MySQL, Amazon RDS, Google Cloud for MySQL and others)
- Existing MySQL database can be merged or synchronized (full scan mode) with MS Access data
- Command line support allows to automate the database migration by timer or run it from 3rd party applications
- Deep customization of the migration process through numerous parameters
- Option to export MS Access database to MySQL script containing SQL statements to create all objects and insert data. This option is designed for those cases when direct connection MySQL server is not allowed.

Conclusion:
Migrating from MS Access to MySQL can be a game-changer for organizations looking to enhance performance, scalability, and security. While MS Access serves well for smaller, less complex databases, MySQL offers a robust solution for handling large datasets and high user demands. However, before jumping into the migration process, it’s crucial to evaluate your actual needs if your database is small with minimal concurrent access, the migration may not bring significant advantages.
For those who decide to proceed, the ETL (Extract-Transform-Load) approach provides a clear and structured method for migration. While manual methods using ODBC drivers can work for basic needs, automated tools like the MS Access to MySQL converter by Intelligent Converters offer a more reliable and efficient solution. With features like full automation, error-free processing, and support for all major MySQL versions, this tool simplifies the migration process and minimizes risks.
Ultimately, the choice between manual and automated methods will depend on your project’s complexity, available resources, and the need for accuracy and speed. By selecting the right method and tools, you can ensure a smooth transition to MySQL, empowering your organization with a powerful, future-ready database management system.
