Introduction to the migration process
Migration procedures apply when you wish to install your Centreon on a different OS (typically, to change from an unsupported OS to a supported OS). You need to install a new OS and a new Centreon platform, then migrate your old data to the new platform.
If you just want to switch to a newer version of Centreon and your current platform is already installed on a supported OS, use the upgrade procedures instead.
The following table describes various cases:
| OS | Version of Centreon | Procedure to be applied |
|---|---|---|
| CentOS 5 | 3.4 | migration |
| CentOS 6 | 3.4 | migration |
| CentOS 7 | 3.4 to 21.10 | upgrade |
| CentOS 8 | 20.10 to 21.10 | migration |
| RHEL 8 | 20.10 to 21.10 | upgrade |
| OL 8 | 20.10 to 21.10 | upgrade |
