open-webui-sqlite-migration 0.1.1

Migrate Open WebUI from SQLite to PostgreSQL

Migrate tool for OpenWebUI SQLite

Migrate from using SQLite database in Open WebUI to use Postgres.

Inspiration from: https://github.com/taylorwilsdon/open-webui-postgres-migration, one of the big differences is that the migration require no input, with environment variables set, you just run the script, no input.

This so you can automate the process, instead of manual input.

Install

You can copy the script to you environment and run it, or you could install it:

pip install open-webui-sqlite-migration

Configuration

Before anything else, backup you SQLite database and keep it in a safe place.

Needed environment variables:

• SQLITE_DB_PATH - exact path to your open webui db, like: /app/backend/data/webui.db.
• MIGRATE_DATABASE_URL - normally the same you should use for DATABASE_URL, like postgresql://user:pass@postgres:5432/openwebui

Also you need to start Open WebUI with DATABASE_URL, so needed tables are created. After that, you remove that variable so you go back to use SQLite. When using SQLite, you run the migration script, then you stop Open WebUI, and then again set DATABASE_URL. If everything now runs smoothly, you can remove the SQLite database. Keep a backup of the database until you are really sure that all things are working as they should.

Migration

• Again - make sure you backup your SQLite database, before doing anything.
• Start Open WebUI with SQLite if it's not running (info logs should say: Context impl SQLiteImpl).
• Stop Open WebUI.
• Start Open WebUI with DATABASE_URL set. Needed tables should be created.
• Stop Open WebUI.
• Remove ENV variable DATABASE_URL, start Open WebUI.
• Run open-webui-migrate-sqlite --dry-run
• Check output, if what is you expected, go to next step.
• Have you really done a backup of your SQLite database?
• Run open-webui-migrate-sqlite
• If all succeeds, restart Open WebUI with DATABASE_URL set.
• You should now be running Open WebUI with Postgres (if you have info logs from Open WebUI, you should see Context impl PostgresqlImpl).
