The benefits of cloning disk on Windows Server 2012
In Windows Server 2012, cloning disk can help a lot:
> Upgrade/replace hard drive: For many reasons, you may want to upgrade your disk to a larger or new one. When you bought a new SSD or HDD, you can clone old hard drive to the new hard drive instead of re-installing OS and other applications to that new hard drive.
> Reactive and restore: Disk clone can be used in system restore. Clean up all data on the original hard drive, and then restore the original data to the hard drive. This operation will recover the functions on the computer and root out the existing virus on computer. It is usually used by internet bar, school, or some other organizations to make sure that if users changed the system settings, and brought virus to the computer, you can quickly restore system to “clean” state by re-activation.
> Prepare for new computer’s installation: you can clone disk with some disk cloning software and install a standard set software to computer so that new users can applying it instantly without waiting installation.
Considering with many aspects, you may want to clone disk in Windows Server 2012.

Clone disk in Windows Server 2012 (R2) step by step
As mentioned above, the Server cloning software AOMEI Partition Assistant Server
can make things easier. Here you can follow the next contents to learn how to use it
for Windows Server 2012 clone disk.
Things to know and prepare
Before you do, here are some things you need to prepare:
1. A new hard drive for storing data. You need to prepare an HDD or an SSD to
clone Windows Server 2012 disk to. Connect it to your Server computer and make sure it can be detected.
2. Confirm what partition type your hard drive is, and make sure your Windows OS is 32Bit or 64Bit. Windows Server 2012 (R2) 32Bit can only boot from MBR disk. If you are planning to clone MBR to GPT disk, it may be unable to boot after being cloned to destination disk. For this situation, you need to upgrade your system to 64 Bit or convert GPT to MBR in Server 2012. However, you can directly clone MBR disk to GPT with Windows Server 2012 (R2) as only as the motherboard supports EFI/UEFI. Otherwise, your system will be unable to boot next time.
3. If you want to clone a GPT hard drive to an MBR disk, the AOMEI Partition
Assistant would change the fourth primary partition and later partitions into logical partition while cloning if there are more than 4 primary partitions on the GPT disk.
4. Install this Server cloning software to your Windows Server 2012.
