+===================================
+Moving Your ownCloud Data Directory
+===================================
+
+There are several reasons to move your ownCloud data directory on an existing 
+installation: to move it outside of your Web root for better security, 
+re-configuring your storage, restoring from backups...whatever the reason, it is 
+a simple operation requiring just a few steps.
+
+First, always have :doc:`current backups <../maintenance/backup>`.
+
+Next, put your ownCloud server into maintenance mode. This is disruptive and 
+will lock out your users, so you might warn them, and select a quiet time. 
+This example is for Ubuntu Linux::
+
+ $ sudo -u www-data php occ maintenance:mode --on
+
+You must run ``occ`` as your HTTP user.
+
+* The HTTP user and group in Debian/Ubuntu is www-data.
+* The HTTP user and group in Fedora/CentOS is apache.
+* The HTTP user and group in Arch Linux is http.
+* The HTTP user in openSUSE is wwwrun, and the HTTP group is www.
+
+Then copy your data directory to its new location, which in this example is 
+``/var/storage``::
+
+ $ sudo cp -r /var/www/owncloud/data /var/storage
+
+Configure your new location in your ``config.php`` file, using the 
+``datadirectory`` parameter::
+
+ 'datadirectory' => '/var/storage/data'
+
+Run ``occ maintenance:repair`` to update the filepaths in your database::
+
+ $ sudo -u www-data php occ maintenance:repair
+
+Take your server out of maintenance mode::
+
+  $ sudo -u www-data php occ maintenance:mode --off
+
+Log in and make sure all your files are there, and your users' files. When 
+everything looks correct, you can delete your old data directory. Remember to 
+adjust your backups to the new location.
