Migration projects involving servers can be categorized in a number of ways, depending on whether you are deploying a new infrastructure, upgrading or consolidating an existing infrastructure, or implementing a new infrastructure such as moving to the cloud. Other variables also include whether you are fully upgrading your entire infrastructure or only some of the server(s). There are also other scenarios such as managed or unmanaged environments, and whether the infrastructure is small or large.

You will find there is no single process for migrating a server but by utilising one or some of the follow migration best practices you will find your upgrade will be successful.

 

Windows Server 2012 has many possible migration scenarios, below I have briefly covered the main ways to move to Server 2012;

  • GreenField – Scenario where there is no current infrastructure, for example a new start up company.

  • Forest Upgrade – Schema upgrade on current infrastructure using ADprep.exe command-line utility.

 

  • Mixed Environment – New hardware with 2012 and upgrade functional level within a legacy OS environment.

 

  • Server Consolidation – Using virtualisation to consolidate multiple physical servers to virtual hosts.

 

  • Private Cloud – Software as a Service (SaaS) / Platform as a Service (PaaS) / Infrastructure as a Service (IaaS) – Utilising AD and System Center 2012.

 

  • Public Cloud – Hosting provider maintains a shared pool of resources – all customer data is fully isolated from others. Services such as Office 365 and Windows Azure offer this public cloud technology.
