Why migrate Windows Server 2012 R2 to new hardware

Modern technology is changing rapidly and you won't always be stuck with the same equipment. For example, you may want to transfer your Windows Server 2012 (R2) to new hardware for the following reasons:

Server upgrade: Usually, there could be some hardware problems if your Windows Server machine is really old. And you may want to upgrade to a new server. However, reinstalling the operating system and other apps on the new server may be a troublesome thing for most of you. Therefore, you could migrate Windows Server 2012 R2 to new hardware directly.
Unify configuration: Sometimes, especially in companies, you may need to install the same system like Windows Server 2012 R2 and applications to many computers. As we all know, it will take a long time to install each of them one by one. So, migrating Windows Server 2012 R2 to other computers directly may be an easier way.

How to migrate Windows Server 2012 R2 to new hardware

Many users know the concept of system or disk cloning. When migrating Windows Server 2012 R2 to another disk on the same machine, using Windows Server migration tools would be the easiest option. But it's not as simple to migrate Windows Server to different machine - it also involves the compatibility of boot files on different hardware.

You may also think of bare-metal backups, which are a common means of data protection on Windows Server and can be used to recover a machine that has no system or the system has crashed. However, according to Microsoft, such backups are only guaranteed to restore the same physical machine, or different physical computers with the same hardware (same make, model and configuration).

bare metal backup

Although some articles indicate that you can do AD forest recovery of different machines with a full server backup, it is highly unlikely to go wrong in practical applications. Therefore:

👉If you want to transfer Windows Server 2012 R2 to a machine with the same hardware, then you can just use the built-in Windows Server backup and system image recovery.
👉If you want to migrate Windows Server 2012 R2 to different hardware, it is recommended to use a dedicated tool that supports Universal Restore (restore system image to dissimilar hardware). It can resolve the boot issue.

In the following article, I will illustrate both the 2 methods below to help you migrate Windows Server 2012 R2.

Way 1: Migrate Windows Server 2012 R2 via Windows Server Backup

Windows Server has its built-in migration tool called Windows Server Backup. With it, you could create a system image and then restore image to your new hardware. If you don't have this tool on your computer, you can install Windows Server Backup first from Server Manager.

Steps to migrate Windows Server using Windows Server Backup

Here I will show you how to migrate Windows Server 2012 R2 with via the backup and restore way. Before restoration, you need to create a system image backup that includes everything you want to migrate, and complete some other preparations step by step.

Create Windows Server Backup

Use Windows Server Backup to create a full backup that can be used for bare metal recovery. To be specific, you can either select "Full server" in Select Backup Configuration, or select "Customize" -> "Bare metal recovery".

*Amont the two, Full server backup is anything in your system, and Bare metal backup is anything that is needed for your system's OS and its apps. Bare metal backup is included in Full server backup.

Select Backup Configuration

Prepare recovery disk or installation disk

To perform a system image recovery, you need a Windows Server recovery disk or installation disc of corresponding OS to access Windows Recovery Environment. For example, if you want to restore Windows Server 2012 R2, the recovery disk must be made in Windows Server 2012 R2.

*If the target machine has no system, you need to use Windows installation disk because system repair disc, because recovery drive won’t work on non-system computers.

Make sure the target drive has enough disk space

If you want to restore Windows Server to a new machine, the new hard drive needs to be in the same size or larger than the source disk.

Make sure the boot mode is correct

The target computer should have the same boot mode (Legacy/UEFI) as the source computer. Otherwise, you will likely receive errors during restoration.

You can boot into BIOS to ensure the boot mode is the same, or manually reconfigure it. If you change the boot mode, remember to convert disk into the corresponding partition style.

After restoring, you could boot the new Windows Server 2012 R2 machine. And system, settings, and installed programs are the same as the old machine.

Way 2: Migrate Windows Server to Dissimilar Hardware Securely

As said above, with Windows Server Backup, you can hardly transfer Windows Server to another server with different firmware. Also, it doesn't allow you to restore system image to a smaller disk. If you want more flexibility, and avoid errors such as system image restore fails because of UEFI/BIOS, you may consider using the professional Windows Server migration software - AOMEI Backupper Server.
