Write Migrations Manually (config v2)


While the Hasura Console can auto generate Migrations for every action, sometimes you might want to write the Migrations yourself, by hand. Using the Hasura CLI, you can bootstrap these migration files and write the SQL for the Postgres schema.


For config v3, see Writing Migrations manually.

Create migration manually

  1. Set up the migration files:

    hasura migrate create <name-of-migration>

    This command will create up and down migration SQL files in the migrations directory.

  2. Edit the file and add your migration actions. For the file format and instructions on what actions can be added, refer to migration file format.

  3. The corresponding Hasura Metadata changes, if any, can be made directly in the appropriate Metadata file in the /metadata directory, refer to Metadata format.

  4. Apply the Migration and Metadata:

    hasura migrate apply
    hasura metadata apply
