# Manual ownCloud Upgrade

Warning

When upgrading from oC 9.0 to 9.1 with existing Calendars or Adressbooks please have a look at the Release Notes of oC 9.0 for important info about the needed migration steps during that upgrade.

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

Put your server in maintenance mode. This prevents new logins, locks the sessions of logged-in users, and displays a status screen so users know what is happening. There are two ways to do this, and the preferred method is to use the occ command, which you must run as your HTTP user. This example is for Ubuntu Linux:

    sudo -u www-data php occ maintenance:mode --on

The other way is by entering your `config.php` file and changing `'maintenance' => false,` to `'maintenance' => true,`.

1. Back up your existing ownCloud Server database, data directory, and `config.php` file. (See Backing up ownCloud.)

2. Download and unpack the latest ownCloud Server release (Archive file) from owncloud.org/install/ into an empty directory outside of your current installation.

   Note

   To unpack your new tarball, run: tar xjf owncloud-[version].tar.bz2

Note

Enterprise users must download their new ownCloud archives from their accounts on https://customer.owncloud.com/owncloud/

3. Stop your Web server.

4. Rename your current ownCloud directory, for example `owncloud-old`.

5. Unpacking the new archive creates a new `owncloud` 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/owncloud`.

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

7. If you keep your `data/` directory in your `owncloud/` directory, copy it from your old version of ownCloud to your new `owncloud/`. If you keep it outside of `owncloud/` 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 `owncloud/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. Restart your Web server.

10. Now launch the upgrade from the command line using `occ`, like this example on CentOS Linux:

        sudo -u apache php occ upgrade

> The optional parameter to skip migration tests during this step was removed in oC 9.2. See Testing a Migration for background information.

> See Using the occ Command to learn more.

11. 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.

Assuming your upgrade succeeded, disable the maintenance mode:

    sudo -u www-data php occ maintenance:mode --off

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. Then apply strong permissions to your ownCloud directories (Set Strong Directory Permissions).
