Hello
I'm sorry but I closed my first topic on purpose. I migrated Centreon 21.10 which was on CentOS 7 to Alma9.
For the Central everything went well but for the collector I would like to have the step-by-step procedure for the migration which is also on Centos7 and Centreon 21.10. On the Centreon procedure he does not detail enough: https://docs.centreon.com/fr/docs/migrate/migrate-from-el-to-el/ I also want to keep the same IP address the same name and keep the same configuration if possible.
To do this, do you have to remove the old collector and put the other one back? Because by putting the new one it tells me that it already exists, even if I delete it in the centreon console.
