Upgrade ownCloud 9 to ownCloud 10

Pre-requisites

Well, before you can begin the upgrade process, ensure that you meet the following minimums;

• The upgrade process involves putting the server in maintenance mood. Hence notify users on the same.
• Make a backup of your ownCloud server  data directory, config.php, 3rd party apps and ownCloud database.
• If any third party application is installed, review them for compatibility and disable them before upgrade. You can re-enable them after upgrade in case they are compatible.

Update the server

Update and upgrade your server to ensure that other ownCloud mandatory requirements are updated.

apt update && apt upgrade -y

There are three ways in which ownCloud server can be upgraded;

• Manually upgrade method using the latest release ownCloud source code. This is the recommended method.
• Using OS specific distribution package manager in conjunction with official ownCloud repositories.
• Using Updater App in the case where admins have no command line access to the server.

In this guide, we are going to learn how to upgrade ownCloud using, of course, the recommended method, manual upgrade.

Manual ownCloud Upgrade

As mentioned above, make the necessary backups as shown below;

Backup ownCloud server directory;

rsync -avpP /var/www/owncloud /opt/backups/

This ensures that a copy is made with permissions preserved.

Backup the ownCloud database;

mysqldump -u root -p owncloud > /home/amos/owncloud-`date +%F`.sql

Now, if you check you home folder;

ls -l /home/amos/
total 68
drwxr-xr-x 17 amos amos  4096 Nov 30 17:09 owncloud
-rw-r--r--  1 amos amos 63216 Dec  1 11:19 owncloud-2018-12-01.sql

NOTE: You can as well take a snapshot of the current state of your server so that you can always restore to it in case things go south. Nothing outdo a snap of the finger restore!!

Enable ownCloud Maintenance Mode

Before you can proceed, put ownCloud on maintenance mode. This prevents new logins and locks the sessions of the logged in users. ownCloud will also display the status on the web UI to let users know what is happening.

To enable maintenance mode, you can edit the /var/www/owncloud/config/config.php and change the value of 'maintenance' =>false, to 'maintenance' => true,. This can also be simply done by the use of occ command as shown below;

sudo -u www-data php /var/www/owncloud/occ maintenance:mode --on

Now, if you try to access ownCloud, you will see a status informing you of the state.

Stop Cron Jobs

systemctl stop cron

Stop the Web Server

systemctl stop apache2

Download the Latest ownCloud Server Release

Navigate to ownCloud download page and obtain the latest release  source archive. Once you obtain the source archive link, you can simply download it as follows;

wget https://download.owncloud.org/community/owncloud-10.0.10.tar.bz2 -P /tmp/

Prepare ownCloud for Upgrade

Once the download is done, rename the original ownCloud folder an extract the new source archive to ownCloud web root directory, /var/www/.

mv /var/www/owncloud /var/www/owncloud-bak
tar xjf /tmp/owncloud-10.0.10.tar.bz2 -C /var/www/

Copy the old ownCloud data directory to the new source directory.

rsync -avpP /var/www/owncloud-bak/data /var/www/owncloud/

Replace the new config.php file with the old one;

rsync -avpP /var/www/owncloud-bak/config /var/www/owncloud/

Upgrade ownCloud

Once you have  your old data in place, run the command below to upgrade ownCloud.

sudo -u www-data php /var/www/owncloud/occ upgrade

Once the upgrade is done, you can verify the version of ownCloud by running the command below;

sudo -u www-data php /var/www/owncloud/occ -V
ownCloud is in maintenance mode - no app have been loaded

ownCloud 10.0.10

If you had any old Apps, you can now copy them to the new Apps directory.

Upgrade PHP to PHP 7.2

ownCloud recommends the use of PHP 7.2 in new installations. Note that there are no official PHP 7.2 repositories on Ubuntu 16.04. Thanks to Ondřej Surý’s  PHP PPA repositories. Therefore, add the PPA respos and make the necessary updates.

add-apt-repository ppa:ondrej/php
apt update

You can optionally remove PHP 7.0 and install php7.2

apt remove php7.0*
apt autoremove
apt install php7.2 libapache2-mod-php7.2 php7.2-common php7.2-curl php7.2-gd php7.2-intl\
 php7.2-json php7.2-ldap php7.2-mbstring php7.2-mysql php7.2-xml php7.2-zip php7.2-bz2

Verify the version.

php -v
PHP 7.2.12-1+ubuntu16.04.1+deb.sury.org+1 (cli) (built: Nov 12 2018 09:55:12) ( NTS )
Copyright (c) 1997-2018 The PHP Group

    with Zend OPcache v7.2.12-1+ubuntu16.04.1+deb.sury.org+1, Copyright (c) 1999-2018, by Zend Technologies

Disable Maintenance Mode

If the upgrade is successful, disable maintenance mode by running the command below;

sudo -u www-data php /var/www/owncloud/occ maintenance:mode --off

Restart the Webserver

Start your cron job service and the web server

systemctl restart cron
systemctl restart apache2

You can now login to your new ownCloud server. You should be welcomed by a new ownCloud X web interface.
