Hello,

I’m in the process to upgrade/mirgrate from 21.04 to 24.10.

The “Central” is working and now I’m deploying new “Remote Poller” by following the procedure :

Migrate from an EL-type OS to Debian | Centreon Documentation

So I install a fresh Debian 12 and install the package as indicated here Migrate from an EL-type OS to Debian | Centreon Documentation

However the documentation is unclear to me …

Once the remote poller installation is OK, I just have to replace the configuration on the central and try to push the configuration ?

If its the case, then the conf cannot be pushed.

Should we “register the server” ? I suppose no as its already registered.

Thanks for your support.

Replying to myself.

I created the new remote poller then switch the configuration to these new pollers.

Finnaly, I change the monitoring poller on all my host.

Once everything was OK, I deleted the old pollers from the configuration.

I still don’t know if it is the good way to do it.

    Hello

    Yes I did the same thing.

    However, my hosts have already allowed pollers list in their config (snmp & other) because I always reserve 2 IP’s  (one for the current poller and one for the future poller) on every site that I have a poller.

    Yes of course, you have to allow the new IP for the queries 🙂

    SNMP, NSCLIENT, firewall rules ...
