This step once again depends entirely on the web server software used to

serve Kallithea.

If you were running Kallithea 0.3.x or older and were using ``paster serve

my.ini`` before, then the corresponding command in Kallithea 0.4 and later is::

    gearbox serve -c new.ini

Before starting the new version of Kallithea, you may find it helpful to

clear out your log file so that new errors are readily apparent.

.. note::

    If you're using Celery, make sure you restart all instances of it after

    upgrade.

10. Update Git repository hooks

-------------------------------

It is possible that an upgrade involves changes to the Git hooks installed by

Kallithea. As these hooks are created inside the repositories on the server

filesystem, they are not updated automatically when upgrading Kallithea itself.

* Go to *Admin > Settings > Remap and Rescan*

* Select the checkbox *Install Git hooks*

* Click the button *Rescan repositories*

.. note::

    Kallithea does not use hooks on Mercurial repositories. This step is thus

    not necessary if you only have Mercurial repositories.
