GLPI 9.3 convert tables to innodb


Message alerte après mise à jour

Since version 9.3 of GLPI, the new installations use the InnoDB storage format instead of MyISAM. When updating your GLPI, the tables will not be automatically migrated. The migration must be done by hand. When connecting to your site you will have an alert message telling you that tables are not in the correct storage format

Convert tables to INNODB format

The developers of GLPI have created a script that allows you to do the migration, it is in REPERTOIRE_GLPI / scripts / innodb_migration.php With a small database, it is possible to launch the script directly from a browser. I strongly advise against this solution which can damage your database. To migrate the database we will use GLPI in CLI mode, ie execute the script directly from a command prompt for Windows or from a console on Linux.
