Migration Guide to FB 3

Firebird 3

Why a Migration Guide?

Note: If you intend to move to Firebird 4, check the Migration Guide to Firebird 4 page.

Firebird 3 brings numerous innovations, such as the long-awaited full SuperServer’s SMP support, network and database encryption, local user authentication in the database, improvements in the communication protocol, in addition to several new features in different areas of the DBMS. All this made the migration process from an older Firebird version a bit more complicated than it was in previous versions, where, basically, all you had to do was replace the server with the new Firebird version or, at worst, a backup and restore of the database.

With Firebird 3, you have different user management plugins allowing the same user to exist in several different plug-ins, with different passwords. The SYSDBA is now optional, as well the use of the security database (you can use any existing database as the security database). You can do this short test and see if you are prepared for Firebird 3.

This Guide will help you in the process of migrating your existing databases and servers to Firebird 3, avoiding headaches and bad surprises!

The guide is now available both in PDF format (128 pages) and printed. The table of contents can be seen in the end of this page.

See what some readers are saying about the Guide:

The migration guide has been VERY helpful and saved me a lot of time. I have been making changes to our product and its installation. Your guide made it very easy to understand what changes were needed to transition to FB 3.

Thanks for putting this eBook together! It is certainly well worth the money I paid for it. 

Best, Mike Simmons

I appreciate your book.  It is very informative and well written.  I review almost all of it yesterday evening.  I hope you have more books in your Firebird 3 future.  Thank you very much. Sincerely, Robert Firl

Though called a migration guide, this well designed manual provides far more information than simply being relegated to how to move between earlier versions of the Firebird Database Engine and the most recent version of this highly capable database system…It is by far one of the superior manuals I have read over the years on the subject of database systems.
