What are the best practices for migrating a central server and a poller?
Old debian 11 architecture : 1 central 1 poller on (centreon 24.04)
New debian12 architecture : 1 central 1 poller on (centreon 24.04)

ps: I cannot upgrade the system because my VMs are in the cloud and it is not recommended on Azure and not functional.

I have the backups YYYY-MM-DD-central.tar.gz, YYYY-MM-DD-centreon.sql.gz, YYYY-MM-DD-centreon_storage.sql.gz and YYYY-MM-DD-centreon-engine .tar.gz. But also the zip saving of templates via the Web Import/Export API module: “centreon-clapi-export-*********.zip”

For information, the name of the central servers, poller and their IPs will change.

In what orders should I proceed, should I follow the restoration procedure simply as in this procedure https://docs.centreon.com/fr/docs/administration/backup/#restauration-dun-serveur-central-centreon or rather follow the migration procedure like this https://docs.centreon.com/fr/docs/migrate/migrate-from-el-to-debian/#migrer-une-plateforme ?

Thanks in advance

Hi,

If you plan to migrate the same version of Centreon (24.04) from Debian 11 to Debian 12 I guess you have a chance of succeed by -importing the SQL database after you installed Centreon on the new Debian 12 host..

I’don’t think you have many option, CLAPI is nor reliable from my experience. About your question precisely, this is clearly a migration you’re about yo do, not a recover. I I were you I would ensure your database export is done with the exact same 24.04.X version which you plan to re-import the data to. Mind the version of all the part of Centreon (Engine, Broker, Web, etc…)

Going to be tricky anyway, good luck.
