Upgrade

Some versions may require changes to the database. These changes or database "migrations" are applied automatically and safely, but, it is recommended to take a backup of the Postgres database before running the --upgrade option, especially if you have made customizations to the database tables.

Binary​

  • Download the latest release and extract the listmonk binary.
  • ./listmonk --upgrade to upgrade an existing DB. Upgrades are idempotent and running them multiple times have no side effects.
  • Run ./listmonk and visit http://localhost:9000.

Docker​

  • docker compose pull to pull the latest version from DockerHub.
  • docker compose run --rm app ./listmonk --upgrade to upgrade an existing DB.
  • Run docker compose up app db and visit http://localhost:9000.

Railway​

  • Head to your dashboard, and select your Listmonk project.
  • Select the GitHub deployment service.
  • In the Deployment tab, head to the latest deployment, click on the three vertical dots to the right, and select "Redeploy".

Downgrade​

To restore a previous version, you have to restore the DB for that particular version. DBs that have been upgraded with a particular version shouldn't be used with older versions. There may be DB changes that a new version brings that are incompatible with previous versions.

General steps:

  1. Stop listmonk.
  2. Restore your pre-upgrade database.
  3. If you're using docker compose, edit docker-compose.yml and change listmonk:latest to listmonk:v2.4.0 (for example).
  4. Restart.

Example with docker:

  1. Stop listmonk (app):
sudo docker stop listmonk_app
  1. Restore your pre-upgrade db (required) (be careful, this will wipe your existing DB):
psql -h 127.0.0.1 -p 9432 -U listmonk
drop schema public cascade;
create schema public;
\q
psql -h 127.0.0.1 -p 9432 -U listmonk -W listmonk < listmonk-preupgrade-db.sql
  1. Edit the docker-compose.yml:
x-app-defaults: &app-defaults
  restart: unless-stopped
  image: listmonk/listmonk:v2.4.0
  1. Restart: sudo docker compose up -d app db nginx certbot
