    in the past i have already asked something like that. But now the environment is a little bit different.
    We have a stack assembled in that way:

    - one master ispconfig (now centos, but in a very near future will be debian 10)
    - several slave ispconfig debian 10
    - several salve ispconfig centos/redhat/fedora that we want keep in legacy fashion

    But we also want upgrade all the ispconfig version to the latest.
    Now. On the master and on the slave debian 10 i don't see problems. But what on the centos/redhat/fedora one? What kind of risk we encouter on that? Is it possible that they still run however, also if they miss some of the newer features?

    The ISPConfig version on all nodes must be the same, otherwise the data replication will fail when the database scheme between master and slave node differs. You can probably update ISPConfig on older and unsupported OS, but it can happen then that config files contain settings which are not supported by the configured service. In such a case, you would have to fix the config files manually and you might have to create custom config templates that do not contain these settings.
