    Hello!
    For some reason I have very outdated cluster, consist of:

    ISPConfig 3.2.4

    1. panel and NS1 CentOS 8.5.2111
    2. ns2 Red Hat Enterprise Linux release 8.10
    3. mail CentOS 8.5.2111
    4. web Red Hat Enterprise Linux release 8.10
    5. web Red Hat Enterprise Linux release 8.10

    Is there any simple way to upgrade all OS (to RockyLinux) and ISPConfig itself transparently for clients, without any changes in hostnames and all cluster configuration?

    Thanks!
