There are many scenarios in which 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 working 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.
Note: As a general note, modern deployments should always make use of a configuration management system wherever possible, whether they are designed to be transient Kubernetes nodes or they are running a combination of system services and containerized software. This guide will be primarily useful when this is not the case, and services need to be cataloged and migrated manually.
In this guide, you will review how to prepare your source and target systems for a migration. This will include getting your two machines to communicate with SSH keys, and an investigation into which components need to be transferred. You will begin the actual migration in the next article in this series.

Migrating to a new server can be a complex and involved task. Not only do you have to transfer the data itself to a new location, you also have to replicate the service environment and ensure that your components interact as you expect them to.
In this series, we will take you through the steps needed to migrate an existing installation to a new server. Follow along to start developing your migration plan.
