# 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 : 10.2 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 /root``wget 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`
#### **Restore Data** **`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)**
`chown -R www-data:www-data /var/www/glpi/`
#### **Check the database integrity**
**`cd /var/www/glpi/latest/bin`**
`php console db:check`
**If all good then update the database** **`cd /var/www/glpi/bin`**
`php console db:update`
#### **Remove the installer**
`rm /var/www/glpi/install/install.php`
**GLPI should now be updated.**
