Database Migration from Firebird to MySQL 

Firebird is a free open-source relational database management system with support for multi-user environments. These benefits make it fast, reliable solution for small and medium size databases. However, Firebird doesn’t have some features of the most popular advanced DBMS: integrated replication, full-text search, point-in-time recovery, etc. 

This may be a reason why a lot of companies migrate their databases from Firebird to more capable DBMS. For example, migration from Firebird to MySQL may give the original database more power having in mind essential benefits of target database management system:

  • security of data (MySQL is known as one of the most secure and reliable DBMS)
  • complete transactional support (atomic, consistent, isolated, durable transaction support and row-level locking)
  • tight integration with web (LAML stack became the most popular open source web platform used for numerous web sites)

On the other hand, MySQL is open-source and free just like Firebird. 

Manual database migration from Firebird to MySQL may be complicated and tedious procedure, especially for large corporate databases. Also, there are some differences between two DBMS that must be handles properly: 

  • special processing for specific data types like “blob sub_type 1”
  • different means of escaping strings inside INSERT INTO clauses
  • Firebird string concatenation operator || must be converted into MySQL function CONCAT()

In order to simplify database migration task, avoid errors and data loss some special tools may be used. There are multiple database converters that can migrate from Firebird to MySQL with a bit of clicks of mouse button, available on the market.
