================
Upgrade manually
================

Always start by making a fresh backup and disabling all 3rd party apps.

1. Back up your existing Nextcloud Server database, data directory, and 
   ``config.php`` file. (See :doc:`backup`, for restore information see :doc:`restore`)
2. Download and unpack the latest Nextcloud Server release (Archive file) from 
   `nextcloud.com/install/`_ into an empty directory outside
   of your current installation.
   
   .. note:: To unpack your new tarball, run:
      unzip nextcloud-[version].zip
    

3. Stop your Web server.

4. Rename your current Nextcloud directory, for example ``nextcloud-old``.

5. Unpacking the new archive creates a new ``nextcloud`` directory populated 
   with your new server files. Copy this directory and its contents to the 
   original location of your old server, for example ``/var/www/``, so that 
   once again you have ``/var/www/nextcloud``.

6. Copy the ``config.php`` file from your old Nextcloud directory to your new 
   Nextcloud directory.

7. If you keep your ``data/`` directory in your ``nextcloud/`` directory, copy 
   it from your old version of Nextcloud to your new ``nextcloud/``. If you keep 
   it outside of ``nextcloud/`` then you don't have to do anything with it, 
   because its location is configured in your original ``config.php``, and 
   none of the upgrade steps touch it.

8. If you are using 3rd party applications, look in your new ``nextcloud/apps/`` 
   directory to see if they are there. If not, copy them from your old ``apps/``
   directory to your new one. Make sure the directory permissions of your third
   party application directories are the same as for the other ones.
   
9. Adjust file ownership and permissions::

     chown -R www-data:www-data nextcloud
     find nextcloud/ -type d -exec chmod 750 {} \;
     find nextcloud/ -type f -exec chmod 640 {} \;

10. Restart your Web server.

11. Now launch the upgrade from the command  line using ``occ``, like this 
    example on Ubuntu Linux::
    
     sudo -u www-data php occ upgrade
     
12. The upgrade operation takes a few minutes to a few hours, depending on the 
    size of your installation. When it is finished you will see a success 
    message, or an error message that will tell where it went wrong.

Login and take a look at the bottom of your Admin page to 
verify the version number. Check your other settings to make sure they're 
correct. Go to the Apps page and review the core apps to make sure the right 
ones are enabled. Re-enable your third-party apps.

Previous Nextcloud releases
---------------------------

You'll find previous Nextcloud releases in the `Nextcloud Server Changelog 
<https://nextcloud.com/changelog/>`_.

Troubleshooting
---------------

Occasionally, *files do not show up after a upgrade*. A rescan of the files can 
help::

 sudo -u www-data php console.php files:scan --all

See `the nextcloud.com support page <https://nextcloud.com/support/>`_ for further
resources.

Sometimes, Nextcloud can get *stuck in a upgrade* if the web based upgrade
process is used. This is usually due to the process taking too long and
encountering a PHP time-out. Stop the upgrade process this way::

 sudo -u www-data php occ maintenance:mode --off
  
Then start the manual process::
  
 sudo -u www-data php occ upgrade

If this does not work properly, try the repair function::

 sudo -u www-data php occ maintenance:repair
