This article discusses Flyway's transition from CONF to TOML configuration files. It highlights the advantages of TOML, such as improved readability, flexibility in managing complex database configurations, and support for specifying multiple database environments. It also discusses a few of the differences to be aware of when switching existing Flyway projects to the new config system. Read more
This article demonstrates how to use PowerShell to fetch your login credentials from Windows Credential Manager and pipe them securely to Flyway without ever saving them in any form, such as in a file or environment variable. Read more
This article describes a simple technique that will allow you to use Flyway securely, even in cases where more than just the login credentials need to be protected. It uses a PowerShell technique that converts an encrypted Flyway configuration file into an array of parameters that Flyway can read just as if you were typing them in. Read more
This article demonstrates one way to do branch-based database development with Flyway, using GitHub to manage the branches and Flyway configuration files to allow Flyway to switch smoothly between databases, when we move between branches in GitHub. Read more
How to get started with Flyway, as simply as possible, using PowerShell. This article provides a practice set of Flyway migration scripts that will build the original pubs database on either SQL Server, PostgreSQL, MySQL, MariaDB or SQLite and then migrate it from version to version, making a series of improvements to its schema design.

Explaining some of the 'gotchas' that can trip up the unwary Flyway user, and how to avoid them. One or two of these you'll encounter quickly, such as the case-sensitivity of parameters and arguments. Others, such as potential problems with undo scripts or running scripted callbacks, only when you are tackling more complex development processes. Read more
Phil Factor offers a programmer's guide to Flyway's configuration settings, explaining the different categories of parameters, the role of each of parameter within each category, and how to exploit Flyway's multi-level configuration file system. Read more
Flyway uses a schema history table to track the version of each database, recording in it every versioned migration file applied to build that version. It's worth understanding exactly how Flyway uses this table, the possible dangers of moving it to a non-default location and how to do it safely, if required. Read more
The 'ShouldExecute' script configuration option in Flyway Teams simplifies 'conditional execution' of SQL migration files. This makes it easier to support multiple application versions from the same Flyway project, to deal with different cultural or legislative requirements. It also helps developers handle environmental differences between development, test and staging, such as the need to support multiple versions or releases of the RDBMS. Read more
