DBMS migration

New in version 0.3.0

Removed in version 0.11.0 (may come back in a future version)

The bridge includes a simple script for migrating between database management systems. It simply reads the data from one database and inserts it into another database.

The script is located in mautrix_telegram/scripts/dbms_migrate. It can be ran using

$ python3 -m mautrix_telegram.scripts.dbms_migrate -f <source db> -t <target db>

Both <source db> and <target db> are full database URLs, e.g. sqlite:///mautrix-telegram.db and postgres://user:password@localhost/mautrixtelegram

Steps:

0. Stop the bridge
1. Update the database URI in the config
2. Initialize the new database with alembic upgrade head
   • Inside Docker, you need to be in /opt/mautrix-telegram/ and you need to pass the path to the config with alembic -x config=/data/config.yaml upgrade head
3. Run the database migration script
4. Start the bridge again
