    <p>Found the answer in the <a href="http://flywaydb.org/documentation/faq.html#downgrade" rel="noreferrer">FAQ</a>:</p> <blockquote> <p><strong>What about downgrade scripts/downward migrations?</strong></p> <p>Flyway does NOT support downgrade scripts.</p> <p>While the idea of downgrade scripts (popularized by Rails Migrations) is a nice one in theory, unfortunately it breaks down in practice. As soon as you have destructive changes (drop, delete, truncate, ...), you start getting into trouble. And even if you don't, you end up creating home-made alternatives for restoring backups, which need to be properly tested as well. </p> <p><strong>Downgrade scripts assume the whole migration failed.</strong></p> <p>A migration can fail at any point. If you have 10 statements, it is possible for the 1st, the 5th, the 7th or the 10th to fail. There is simply no way to know in advance. Downgrade scripts are written to roll back an entire migration. This renders them effectively useless, even for non-destructive changes. </p> <p><strong>Maintain backwards compatibility between the DB and all versions of the code currently deployed in production.</strong></p> <p>This way a failed migration is not a disaster. The old version of the application is still compatible with the DB, so you can simply roll back the application code, investigate, and take corrective measures. </p> <p><strong>A much better solution is a proper, well tested, backup and restore strategy.</strong></p> <p>It is independent of the database structure, and once it is tested and proven to work, no migration script can break it. For optimal performance, and if your infrastructure supports this, we recommend using the <strong>snapshot technology of your underlying storage solution</strong>. Especially for larger data volumes, this can be <strong>several orders of magnitude faster</strong> than traditional backups and restores!</p> </blockquote>

    1. COYour best option is of course to use a database that properly supports DDL transactions, such as PostgreSQL. That way, the database will take care of cleaning up the mess for you.

    2. COYou misunderstood the point of my question. I'm not saying I'd like to roll-back in the middle of a transaction in case of a failure. I'm saying a customer has version 4 of the database and I want to roll him back to version 2.

    3. COWhat would be the real life usecase where one would like to roll back multiple successful migrations on a production system?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
