Introduction to the migration process
Learn when to migrate Centreon to a new server or a supported OS instead of upgrading, and choose the migration procedure that matches your OS.
Migrate from an EL-type OS to another EL-type OS (from a Centreon 18.10 or newer)
Migrate a Centreon 18.10 or newer platform from one EL-type OS to another, such as CentOS 7 to Alma 9: install a new server, sync data, then upgrade.
Migrate from an EL-type OS to Debian
Migrate a Centreon 18.10 or newer platform from an EL-type OS such as CentOS 7 to Debian on a new server, synchronize data and databases, then upgrade.
Migrate from Debian 11 to Debian 12
Migrate a Centreon platform from Debian 11 to Debian 12 on another server: install the new central server, synchronize data and databases, then upgrade.
Migrate from a Centreon 3.4 platform
Migrate a Centreon 3.4 platform to a new central server: install it, synchronize data, databases and plugins, then upgrade Centreon and its modules.
Nagios Reader to Centreon CLAPI
Use the Nagios Reader to Centreon CLAPI script to convert Nagios CFG configuration files into CLAPI commands and import them into Centreon.
Migrate a platform with Poller Display module
Migrate a Centreon platform that uses the deprecated Poller Display module: uninstall the module, then register the poller as a Remote Server.
