Reference for Database Migrations

Here’s the list of all the Database Migrations that are executed via when you run airflow db upgrade.

Warning

Those migration details are mostly used here to make the users aware when and what kind of migrations will be executed during migrations between specific Airflow versions. The intention here is that the “DB conscious” users might perform an analysis on the migrations and draw conclusions about the impact of the migrations on their Airflow database. Those users might also want to take a look at the ERD Schema of the Database document to understand how the internal DB of Airflow structure looks like. However, you should be aware that the structure is internal and you should not access the DB directly to retrieve or modify any data - you should use the REST API to do that instead.
