How to move Centreon to another network

Context

My network address changed and I needed to still be able to supervise using Centreon. The address plan stayed the same from one network to the other and I didn't want to install a new Centreon from scratch & redo the setup of all the hosts and services. This is what I did to achieve the move from one network to the other.

Topology

The previous network will be referred to as previous network and the new one as new network. For the sake of this How-to, let's say that on the previous network the network address was 192.168.1.0 and the new network's address is 192.168.2.0.

I had one central Centreon-Central (or even central) and one Centreon-Poller (or poller). This is how I'll refer to these VMs here. We'll say that the central address ends with .2 on both the previous network and the new network, and the poller's ends with .3.
