Which is best Liquibase or Flyway?
Some sources mention using both Liquibase and Flyway together. Liquibase seems to have everything Flyway has and more flexibility when it comes to rollbacks. The main advantage of just Flyway seems to be not having to use XML, but Liquibase allows you to specify an SQL file in their XML.
What is the difference between Liquibase and Flyway?
Liquibase follows a different concept to implement database refactoring. While Flyway supports migration scripts in SQL and Java format only, Liquibase abstracts away from SQL completely and thus decouples database refactoring from the underlying database technology.
Does Liquibase migrate data?
Liquibase facilitates database migrations with not only plain old SQL scripts, but also with different abstract, database-agnostic formats including XML, YAML, and JSON. When we use non-SQL formats for database migrations, Liquibase generates the database-specific SQL for us.
Does Flyway migrate data?
Flyway updates a database from one version to the next using migrations. We can write migrations either in SQL with database-specific syntax, or in Java for advanced database transformations.
What does Flyway baseline do?
Baseline is for introducing Flyway to existing databases by baselining them at a specific version. This will cause Migrate to ignore all migrations up to and including the baseline version. Newer migrations will then be applied as usual.
What is Database migration tool?

Should I use flyway or Liquibase for writing scripts?
If you decide to use Liquibase and write your scripts in one of other supported formats you should easily be able to use the same scripts across different databases. You can do generate diff with Liquibase but not with Flyway, even with its paid version. It was one of main reasons why we chose Liquibase over Flyway in our project.
What is the difference between SSDT and Liquibase/Flyway?
It tackles a different problem although there may be some overlap with Liquibase/Flyway in some aspects of schema migration. But as an overall schema migration tool, Liquibase and Flyway are fully dedicated tools whereas SSDT is more for the design and development of a database.
Why can’t I do a diff between two databases in Flyway?
Flyway also doesn’t have the ability to perform a diff to compare two databases, like Liquibase — Flyway expects that you will also use some external tool to do this. This also means Flyway users can’t do the equivalent of diffChangeLog.
Why choose launchliquibase over Flyway?
Liquibase has the power and flexibility to handle your Day One problems AND your Day 50 problems more gracefully from the get-go. Sure, there are workarounds for Flyway to handle some of these more complex needs, but they’re not pretty.
