Today I've solved the problem of one server being to slow to handle the growth of my zabbix configuration. I'm using zabbix-server 2.2.2 with MySQL/Debian backend and around 20 zabbix-agents with Debian installed.
Let's say old Zabbix server IP is: A.B.C.D and new is: U.X.Y.Z. The domain name for the instalation will be: http://zbx.newmachine.com
Below you will find all steps to migrate your configuration.

I'm doing a hardware refresh on a my Colo, I just need to copy my UFW rules from my old server to my new server. I dont seem to be able to get them copy all the active rules from my old server to my new one.
How do I copy my active UFW rules between servers?

There are many scenarios where you might have to move your data and operating requirements from one server to another. You may need to implement your solutions in a new datacenter, upgrade to a larger machine, or transition to new hardware or a new VPS provider.
Whatever your reasons, there are many different considerations you should make when migrating from one system to another. Getting functionally equivalent configurations can be difficult if you are not operating with a configuration management solution such as Chef, Puppet, or Ansible. You need to not only transfer data, but also configure your services to operate in the same way on a new machine.
In this guide, we will discuss how to prepare your source and target systems for a migration. This will include getting your two machines to communicate with SSH keys and a heavy investigation as to what components need to be transferred. We will work on the actual migration in the next article.
