“I have an HDD that Windows Server 2012 installed on. Now I would like to upgrade it to SSD so that I can boot up operating system faster and load game and program quicker. The problem is that I am unwilling to lose any data on HDD. But I don’t know how to transfer all data including operating system from HDD to SSD on Windows Server 2012? Can I just copy every file one by one on HDD and pasted them into SSD

Why not clone HDD to SSD on Windows Server 2012?

Copy” and “Paste” might be a time-wasting and cumbersome work when you intend to replace HDD with SSD. What’s worse, some system files is inaccessible after pasted into SSD and the system can’t boot properly. It is impracticable to transfer data from HDD to SSD on Windows Server 2012 by copying and pasting files.

Luckily, you can choose to clone HDD to SSD on Windows Server 2012, which can transfer all the content including OS to SSD and you don’t need to reinstall applications and operating system. According to all above, it can be easily concluded that cloning Windows Server 2012 hard drive to SSD is a nice choice to migrate data from HDD to SSD on Windows Server 2012.

How to transfer all data from HDD to SSD on Windows Server 2012?

Under such a circumstance, the question is how to clone HDD to SSD on Windows Server 2012. It is necessary to apply reliable and safe software to assist you to complete this operation. Here it is highly recommended to try AOMEI Partition Assistant Server.

This server cloning software is specially designed for Windows systems. It is compatible with Windows Server 2019/2016/2012 (R2)/2008 (R2)/2003 and other Windows systems like Windows 10. It allows you to clone HDD to SSD/HDD and clone OS drive to SSD without data loss. Then, let’s have a look at the detailed tutorial on how to move all data from HDD to SSD on Windows Server 2012 via it.

PS.: The SSD has to own enough space to store all the data migrated from HDD. Leave 25% or more free space of SSD to gain more stable performance.

Step 1. Connect the SSD to the machine and make sure it can be detected. Then, enter Disk Management to initialize SSD.

Step 2. To migrate data from HDD to SSD Windows Server 2012, run AOMEI Partition Assistant Server. In the main interface, right click the source disk and choose “Clone Disk”.

Select Copy Disk

Step 3. In the pop-up window, choose a proper way to clone HDD to SSD in Server 2012 and click “Next”.

Disk Copying Methods


  • Copy Disk Quickly” just copies the used space of the hard drive to another and “Sector-by-Sector Clone” copies all sectors of the hard drive to another.

  • The former takes less time and demands more space than the latter; the former allows you to adjust partition on the destination disk and nor the latter. The deleted or lost files only can be cloned through the latter.

Step 4. Select a target disk to copy the source disk to. As the target disk is SSD, please place a tick in the box before “Optimize the performance of SSD”. Then, click “Next”.

Select Destination Disk

Step 5. It allows you to adjust the partition size on the target disk. Make your choice and click “Next”.

Edit Partition Size

PS: There are three options for you to choose: “Clone without resize partition”, “Fit partitions to entire disk” and “Edit partitions on this disk”.

Read the pop-up Note about how to boot after clone or migration seriously and remember it. Then click “Finish”.

Boot Note

Step 6. You will return to main menu. Please check the pending operation and click “Apply” > “Proceed” to perform this operation.



  • Reboot is required as the operation has to be completed under PreOS mode.

  • Enter BIOS to set SSD as the first boot option.

  • If the destination disk is GPT style and your machine doesn’t support EFI/UEFI boot mode, you’d better convert GPT into MBR before cloning.

  • You can resize partition after cloning if you are not satisfied with the partition of SSD.

SSD optimization after data migration [Tips]

All in all, AOMEI Partition Assistant Server can help you to transfer data from HDD to SSD on Windows Server 2012 through disk cloning software within simple few steps. However, after realizing how to transfer data from HDD to SSD on Windows Server 2012, in order to gain better performance of SSD, there is something about SSD optimization that you should have knowledge about.

  • Align SSD partition if you didn’t tick the box before “Optimize the performance of SSD” during the cloning process. It is known that SSD adopt the smallest 4k sector in file system to save data. When 4k sector is not aligned, the performance of SSD might be affected.

  • Set SATA controller to AHCI (Advanced Host Controller Interface) mode as it supports NCQ (Native Command Queuing) that is rather important for SSD performance.

  • As it wastes a great number of times, disable Superfetch by pressing Windows +R, entering services.msc, finding Superfetch and disabling Superfetch.
