Version specific instructions
+++++++++++++++++++++++++++++

Upgrade from 0.5 to 0.6
~~~~~~~~~~~~~~~~~~~~~~~

On upgrade to version 0.6 you should run :samp:`./manage.py syncdb` and
:samp:`./manage.py setupgroups --move` to setup access control as described
in installation section.

Upgrade from 0.6 to 0.7
~~~~~~~~~~~~~~~~~~~~~~~

On upgrade to version 0.7 you should run :samp:`./manage.py syncdb` to
setup new tables and :samp:`./manage.py rebuild_index` to build index for
fulltext search.

On upgrade to version 0.8 you should run :samp:`./manage.py syncdb` to setup
new tables, :samp:`./manage.py setupgroups` to update privileges setup and
:samp:`./manage.py rebuild_index` to rebuild index for fulltext search.

Upgrade from 0.8 to 0.9
~~~~~~~~~~~~~~~~~~~~~~~

On upgrade to version 0.9 file structure has changed. You need to move
:file:`repos` and :file:`whoosh-index` to :file:`weblate` folder. Also running
:samp:`./manage.py syncdb`, :samp:`./manage.py setupgroups` and
:samp:`./manage.py setuplang` is recommended to get latest updates of 
privileges and language definitions.

Upgrade from 0.9 to 1.0
~~~~~~~~~~~~~~~~~~~~~~~

On upgrade to version 1.0 one field has been added to database, you need to
invoke following SQL command to adjust it:

On upgrade to version 1.2, the migration procedure has changed. It now uses
South for migrating database. To switch to this new migration schema, you need
to run following commands:

.. code-block:: sh

    ./manage.py syncdb
    ./manage.py migrate trans 0001 --fake
    ./manage.py migrate accounts 0001 --fake
    ./manage.py migrate lang 0001 --fake

Also please note that there are several new requirements and version 0.8 of
django-registration is now being required, see :ref:`requirements` for more
details.

Once you have done this, you can use :ref:`generic-upgrade-instructions`.

Upgrade from 1.2 to 1.3

Since 1.3, :file:`settings.py` is not shipped with Weblate, but only example
settings as :file:`settings_example.py` it is recommended to use it as new base
for your setup.

Upgrade from 1.4 to 1.5
~~~~~~~~~~~~~~~~~~~~~~~

Several internal modules and paths have been renamed and changed, please adjust

* Checks were moved to submodules.
* Locales were moved to top level directory.

The migration of database structure to 1.5 might take quite long, it is
recommended to put your site offline, while the migration is going on.


.. note::

    If you have update in same directory, stale :file:`*.pyc` files might be
    left around and cause various import errors. To recover from this, delete
    all of them in Weblate's directory, for example by 
    ``find . -name '*.pyc' -delete``.

Upgrade from 1.6 to 1.7
~~~~~~~~~~~~~~~~~~~~~~~

The migration of database structure to 1.7 might take quite long, it is
recommended to put your site offline, while the migration is going on.

checks as they might have been wrongly linked to units in previous versions.

Upgrade from 1.7 to 1.8
~~~~~~~~~~~~~~~~~~~~~~~

The migration of database structure to 1.8 might take quite long, it is
recommended to put your site offline, while the migration is going on.

This upgrade also requires you to upgrade python-social-auth from 0.1.x to
0.2.x series, what will most likely to need to fake one of their migrations
(see `Upgrading PSA with South`_ for more information):

    ./manage.py migrate --fake default

    :ref:`django-17`.

Upgrade from 2.0 to 2.1
~~~~~~~~~~~~~~~~~~~~~~~

The filesystem paths configuration has changed, the :setting:`GIT_ROOT` and
:setting:`WHOOSH_INDEX` are gone and now all data resides in
:setting:`DATA_DIR`. The existing data should be automatically migrated by
supplied migration, but in case of non standard setup, you might need to move
these manually.

    If you are upgrading to Django 1.7 in same step, please consult
    :ref:`django-17`.

Upgrade from 2.1 to 2.2
~~~~~~~~~~~~~~~~~~~~~~~

Weblate now supports fulltext search on additional fields. In order to make it
work on existing data you need to udpate fulltext index by:

.. code-block:: sh

    ./manage.py rebuild_index --clean --all

If you have some monolingual translations, Weblate now allows to edit template
(source) strings as well. To see them, you need to reload translations, what
will either happen automatically on next repository update or you can force it
manually:

.. code-block:: sh

    ./manage.py loadpo --all

.. seealso::

    If you are upgrading to Django 1.7 in same step, please consult
    :ref:`django-17`.


.. _django-17:

Upgrading to Django 1.7
-----------------------

Please  adjust your :file:`settings.py` to match several changes in the
configuration (consult :file:`settings_example.py` for correct values).

Django 1.7 has a new feature to handle database schema upgrade called
"migrations" which is incompatible with South (used before by Weblate).

Before migrating to Django 1.7, you first need to apply all migrations from
South. If you already have upgraded Django to 1.7, you can do this using
virtualenv and :file:`examples/migrate-south` script:

.. code-block:: sh

    examples/migrate-south --settings weblate.settings

Once you have done that, you can run Django 1.7 migrations and work as usual.

.. _pootle-migration:

Migrating from Pootle
---------------------

As Weblate was originally written as replacement from Pootle, it is supported
to migrate user accounts from Pootle. All you need to do is to copy
``auth_user`` table from Pootle, user profiles will be automatically created
for users as they log in and they will be asked to update their settings.
Alternatively you can use :djadmin:`importusers` to import dumped user
credentials.
