Migrating a poller to another host machine

In some cases you might want to change the OS of the host machine for your poller. The correct procedure for this is to install a new server and migrate your resources to it.

1. Install a new host machine for your poller as per our prerequisites.

2. Deploy the poller to the new machine.

3. Copy the configuration for the following elements from the old poller to the new one:

   • Custom plugins (example: community plugins, or custom developments)
   • If you are using the centreon-as400 connector (installation and configuration): /etc/centreon-as400/.

4. Move all the resources you want to the new poller.

   1. Go to Configuration > Hosts > Hosts.
   2. Use the Poller list to display only the resources monitored by the poller you want.
   3. Select all hosts using the check box in the left column header.
   4. Select More actions > Mass change and edit the Monitoring server field in the configuration form.
   5. Deploy the configuration for both pollers.

   The resources are now monitored by the new poller: the services monitored by this poller are moved to the other poller automatically.

5. Remove the old poller from your architecture.
