The official Docker image (see :doc:`install/docker`) has all Weblate upgrade steps integrated. There are typically no manual steps needed besides pulling latest version.
.. seealso:: :ref:`upgrading-docker`
Before upgrading, please check the current :ref:`requirements` as they might have changed. Once all requirements are installed or updated, please adjust your :file:`settings.py` to match changes in the configuration (consult :file:`settings_example.py` for correct values).
Always check :ref:`version-specific-instructions` before upgrade. In case you are skipping some versions, please follow instructions for all versions you are skipping in the upgrade. Sometimes it's better to upgrade to some intermediate version to ensure a smooth migration. Upgrading across multiple releases should work, but is not as well tested as single version upgrades.
Note
It is recommended to perform a full database backup prior to upgrade so that you can roll back the database in case upgrade fails, see :doc:`backup`.
Stop wsgi and Celery processes. The upgrade can perform incompatible changes in the database, so it is always safer to avoid old processes running while upgrading.
Upgrade Weblate code.
For pip installs it can be achieved by:
pip install -U "Weblate[all]==version"
Or, if you just want to get the latest released version:
pip install -U "Weblate[all]"
If you don't want to install all of the optional dependencies do:
pip install -U Weblate
With Git checkout you need to fetch new source code and update your installation:
cd weblate-src git pull # Update Weblate inside your virtualenv . ~/weblate-env/bin/pip install -e . # Install dependencies directly when not using virtualenv pip install --upgrade -r requirements.txt # Install optional dependencies directly when not using virtualenv pip install --upgrade -r requirements-optional.txt
New Weblate release might have new :ref:`optional-deps`, please check if they cover features you want.
Upgrade configuration file, refer to :file:`settings_example.py` or :ref:`version-specific-instructions` for needed steps.
Upgrade database structure:
weblate migrate --noinput
Collect updated static files (see :ref:`server` and :ref:`static-files`):
weblate collectstatic --noinput --clear
Compress JavaScript and CSS files (optional, see :ref:`production-compress`):
weblate compress
If you are running version from Git, you should also regenerate locale files every time you are upgrading. You can do this by invoking:
weblate compilemessages
Verify that your setup is sane (see also :ref:`production`):
weblate check --deploy
Restart Celery worker (see :ref:`celery`).
If you are upgrading from 2.x release, always first upgrade to 3.0.1 and then continue upgrading in the 3.x series. Upgrades skipping this step are not supported and will break.
.. seealso:: `Upgrade from 2.20 to 3.0 in Weblate 3.0 documentation <https://docs.weblate.org/en/weblate-3.0.1/admin/upgrade.html#upgrade-3>`_
If you are upgrading from 3.x release, always first upgrade to 4.0.4 or 4.1.1 and then continue upgrading in the 4.x series. Upgrades skipping this step are not supported and will break.
.. seealso:: `Upgrade from 3.11 to 4.0 in Weblate 4.0 documentation <https://docs.weblate.org/en/weblate-4.0.4/admin/upgrade.html#upgrade-from-3-11-to-4-0>`_
Please follow :ref:`generic-upgrade-instructions` in order to perform update.
Notable configuration or dependencies changes:

andjava-format
instead ofjava-messageformat
. - The jellyfish dependency has been replaced by rapidfuzz.
- Changed in 4.14.2: Deprecated insecure configuration of VCS service API keys via _TOKEN/_USERNAME configuration instead of _CREDENTIALS list. In Docker, please add matching _HOST directive. For example see :envvar:`WEBLATE_GITHUB_HOST` and :setting:`GITHUB_CREDENTIALS`.
.. seealso:: :ref:`generic-upgrade-instructions`

btree_gin
extension in PostgreSQL. The migration process will install it if it has sufficient privileges. See :ref:`dbsetup-postgres` for manual setup. - The Docker image no longer enables debug mode by default. In case you want it, enable it in the environment using :envvar:`WEBLATE_DEBUG`.
- The database migration make take hours on larger instances due to recreating some of the indexes.

DEFAULT_PAGINATION_CLASS
in rest framework settings was changed.

CELERY_BEAT_SCHEDULER
and :setting:`django:INSTALLED_APPS` need to be changed for that.
.. seealso:: :ref:`generic-upgrade-instructions`
Weblate no longer supports Python older than 3.6. In case you are still running on older version, please perform migration to Python 3 first on existing version and upgrade later. See Upgrading from Python 2 to Python 3 in the Weblate 3.11.1 documentation.
If you are running Weblate on other dabatase than PostgreSQL, you should consider migrating to PostgreSQL as Weblate performs best with it. The following steps will guide you in migrating your data between the databases. Please remember to stop both web and Celery servers prior to the migration, otherwise you might end up with inconsistent data.
It is usually a good idea to run Weblate in a separate database, and separate user account:
# If PostgreSQL was not installed before, set the main password
sudo -u postgres psql postgres -c "\password postgres"
# Create a database user called "weblate"
sudo -u postgres createuser -D -P weblate
# Create the database "weblate" owned by "weblate"
sudo -u postgres createdb -E UTF8 -O weblate weblate
The simplest approach for migration is to utilize Django JSON dumps. This works well for smaller installations. On bigger sites you might want to use pgloader instead, see :ref:`pgloader-migration`.
- Add PostgreSQL as additional database connection to the :file:`settings.py`:
DATABASES = {
"default": {
# Database engine
"ENGINE": "django.db.backends.mysql",
# Database name
"NAME": "weblate",
# Database user
"USER": "weblate",
# Database password
"PASSWORD": "password",
# Set to empty string for localhost
"HOST": "database.example.com",
# Set to empty string for default
"PORT": "",
# Additional database options
"OPTIONS": {
# In case of using an older MySQL server, which has MyISAM as a default storage
# 'init_command': 'SET storage_engine=INNODB',
# Uncomment for MySQL older than 5.7:
# 'init_command': "SET sql_mode='STRICT_TRANS_TABLES'",
# If your server supports it, see the Unicode issues above
"charset": "utf8mb4",
# Change connection timeout in case you get MySQL gone away error:
"connect_timeout": 28800,
},
},
"postgresql": {
# Database engine
"ENGINE": "django.db.backends.postgresql",
# Database name
"NAME": "weblate",
# Database user
"USER": "weblate",
# Database password
"PASSWORD": "password",
# Set to empty string for localhost
"HOST": "database.example.com",
# Set to empty string for default
"PORT": "",
},
}
- Run migrations and drop any data inserted into the tables:
weblate migrate --database=postgresql
weblate sqlflush --database=postgresql | weblate dbshell --database=postgresql
- Dump legacy database and import to PostgreSQL
weblate dumpdata --all --output weblate.json
weblate loaddata weblate.json --database=postgresql
- Adjust :setting:`django:DATABASES` to use just PostgreSQL database as default, remove legacy connection.
Weblate should be now ready to run from the PostgreSQL database.
The pgloader is a generic migration tool to migrate data to PostgreSQL. You can use it to migrate Weblate database.
Adjust your :file:`settings.py` to use PostgreSQL as a database.
Migrate the schema in the PostgreSQL database:
weblate migrate weblate sqlflush | weblate dbshell
Run the pgloader to transfer the data. The following script can be used to migrate the database, but you might want to learn more about pgloader to understand what it does and tweak it to match your setup:
LOAD DATABASE FROM mysql://weblate:password@localhost/weblate INTO postgresql://weblate:password@localhost/weblate WITH include no drop, truncate, create no tables, create no indexes, no foreign keys, disable triggers, reset sequences, data only ALTER SCHEMA 'weblate' RENAME TO 'public' ;
As Weblate was originally written as replacement from Pootle, it is supported to migrate user accounts from Pootle. You can dump the users from Pootle and import them using :djadmin:`importusers`.
