+Migrating from MySQL/MariaDB to PostgreSQL
+==========================================
+
+Our recommended database for all production installations is PostgreSQL. Support for MySQL/MariaDB will be removed in
+pretix 5.0.
+
+In order to follow this guide, your pretix installation needs to be a version that fully supports MySQL/MariaDB. If you
+already upgraded to pretix 5.0, downgrade back to the last 4.x release using ``pip``.
+
+.. note:: We have tested this guide carefully, but we can't assume any liability for its correctness. The data loss
+          risk should be low as long as pretix is not running while you do the migration. If you are a pretix Enterprise
+          customer, feel free to reach out in advance if you want us to support you along the way.
+
+Update database schema
+----------------------
+
+Before you start, make sure your database schema is up to date::
+
+    # sudo -u pretix -s
+    $ source /var/pretix/venv/bin/activate
+    (venv)$ python -m pretix migrate
+
+Install PostgreSQL
+------------------
+
+Now, install and set up a PostgreSQL server. For a local installation on Debian or Ubuntu, use::
+
+    # apt install postgresql
+
+Having the database server installed, we still need a database and a database user. We can create these with any kind
+of database managing tool or directly on our database's shell. Please make sure that UTF8 is used as encoding for the
+best compatibility. You can check this with the following command::
+
+    # sudo -u postgres psql -c 'SHOW SERVER_ENCODING'
+
+Without Docker
+""""""""""""""
+
+For our standard manual installation, create the database and user like this::
+
+    # sudo -u postgres createuser pretix
+    # sudo -u postgres createdb -O pretix pretix
+
+With Docker
+"""""""""""
+
+For our standard docker installation, create the database and user like this::
+
+    # sudo -u postgres createuser -P pretix
+    # sudo -u postgres createdb -O pretix pretix
+
+Make sure that your database listens on the network. If PostgreSQL on the same same host as docker, but not inside a docker container, we recommend that you just listen on the Docker interface by changing the following line in ``/etc/postgresql/<version>/main/postgresql.conf``::
+
+    listen_addresses = 'localhost,172.17.0.1'
+
+You also need to add a new line to ``/etc/postgresql/<version>/main/pg_hba.conf`` to allow network connections to this user and database::
+
+    host    pretix          pretix          172.17.0.1/16           md5
+
+Restart PostgreSQL after you changed these files::
+
+    # systemctl restart postgresql
+
+If you have a firewall running, you should also make sure that port 5432 is reachable from the ``172.17.0.1/16`` subnet.
+
+Of course, instead of all this you can also run a PostgreSQL docker container and link it to the pretix container.
+
+Stop pretix
+-----------
+
+To prevent any more changes to your data, stop pretix from running::
+
+    # systemctl stop pretix-web pretix-worker
+
+Change configuration
+--------------------
+
+Change the database configuration in your ``/etc/pretix/pretix.cfg`` file::
+
+    [database]
+    backend=postgresql
+    name=pretix
+    user=pretix
+    password=  ; only required for docker or remote database, can be kept empty for local auth
+    host=      ; set to 172.17.0.1 in docker setup, keep empty for local auth
+
+
+Create database schema
+-----------------------
+
+To create the schema in your new PostgreSQL database, use the following commands::
+
+    # sudo -u pretix -s
+    $ source /var/pretix/venv/bin/activate
+    (venv)$ python -m pretix migrate
+
+
+Migrate your data
+-----------------
+
+Install ``pgloader``::
+
+    # apt install pgloader
+
+.. note::
+
+   If you are using Ubuntu 20.04, the ``pgloader`` version from the repositories seems to be incompatible with PostgreSQL
+   12+. You can install ``pgloader`` from the `PostgreSQL repositories`_ instead.
+   See also `this discussion <https://github.com/pretix/pretix/issues/3090>`_.
+
+Create a new file ``/tmp/pretix.load``, replacing the MySQL and PostgreSQL connection strings with the correct user names, passwords, and/or database names::
+
+    LOAD DATABASE
+        FROM mysql://pretix:password@localhost/pretix  -- replace with mysql://username:password@hostname/dbname
+        INTO postgresql:///pretix                      -- replace with dbname
+
+    WITH data only, include no drop, truncate, disable triggers,
+         create no indexes, drop indexes, reset sequences
+
+    ALTER SCHEMA 'pretix' RENAME TO 'public'           -- replace pretix with the name of the MySQL database
+
+    ALTER TABLE NAMES MATCHING ~/.*/
+        SET SCHEMA 'public'
+
+    SET timezone TO '+00:00'
+
+    SET PostgreSQL PARAMETERS
+         maintenance_work_mem to '128MB',
+         work_mem to '12MB';
+
+Then, run::
+
+    # sudo -u postgres pgloader /tmp/pretix.load
+
+The output should end with a table summarizing the results for every table. You can ignore warnings about type casts
+and missing constraints.
+
+Afterwards, delete the file again::
+
+    # rm -rf /tmp/pretix.load
+
+Start pretix
+------------
+
+Now, restart pretix. Maybe stop your MySQL server as a verification step that you are no longer using it::
+
+    # systemctl stop mariadb
+    # systemctl start pretix-web pretix-worker
+
+And you're done! After you've verified everything has been copied correctly, you can delete the old MySQL database.
+
+.. note:: Don't forget to update your backup process to back up your PostgreSQL database instead of your MySQL database now.
