GLPI Update (with GLPI 11 Upgrade investigation)

Turn ON Maintenance Mode

Before backing up, you must enable maintenance mode.

cd /var/www/glpi

php bin/console glpi:maintenance:enable

Backups

First, you have to backup some data before processing any upgrade

backup your database;

mysqldump -u root -p --databases glpi > /root/backup/glpi-oldversion.sql

backup your config directory, especially for your GLPI key file (config/glpi.key or config/glpicrypt.key) which is randomly generated; backup your files directory, it contains users and plugins generated files, like uploaded documents; backup your marketplace and plugins directory.

mkdir /root/backup/backup_glpi/glpi-old_version

cp -Rf /var/www/glpi/ /root/backup/backup_glpi/old_version

Check soft version

Before attempting any upgrade, you need to check the version of the software to make sure if it is compatible!

cd /var/www/glpi

php bin/console glpi:system:check_requirements

php bin/console glpi:database:check_schema_integrity

GLPI 10.0.5

GLPI 10.0.10

GLPI 11.0.0

PHP Minimum : 7.4

PHP Maximum : 8.2

PHP Minimum : 7.4

PHP Maximum : 8.3

PHP Minimum : 8.2

PHP Maximum : ??

MariaDB Minimum : 10.2

MariaDB Minimum : 10.5

Ubuntu 20.04 LTS	Ubuntu 22.04 LTS	Ubuntu 24.04 LTS
PHP 7.4	PHP 8.1	PHP 8.3
MariaDB 10.3	MariaDB : 10.5	MariaDB : 10.6

With this example, you can see that GLPI 10.0.10 requires Ubuntu 20.04 minimum.

But GLPI 11.0.0 requires Ubuntu 22.04 minimum.

Do not upgrade your system or GLPI without checking the versions of the components supported by GLPI !

Update GLPI version

Remove the old GLPI version

rm -Rf /var/www/glpi/

Download the latest GLPI version and uncompress it

cd /rootwget https://github.com/glpi-project/glpi/releases/download/XX.X.X/glpi-XX.X.X.tgz

tar -xvf glpi-XX.X.X.tgz

Move it to the right location and add the version number in the folder name

mv glpi /var/www/glpi

cp -Rf /root/backup/backup_glpi/your_version/glpi/files /var/www/glpi/cp -Rf /root/backup/backup_glpi/your_version/glpi/plugins /var/www/glpi/cp -Rf /root/backup/backup_glpi/your_version/glpi/config /var/www/glpi/cp -Rf /root/backup/backup_glpi/your_version/glpi/marketplace /var/www/glpi/

Change the symlink to make it point on the latest version (and ensure the file are owned by www-data)
