?What does system migration mean

A system migration(also known as system clone) refers to a process of transferring the current operating system, data, and software to a new hard drive and make it bootable, so you can use it to replace the old hard drive without reinstalling Windows. Also, you can use it as a data backup to prevent any disaster.

To be specific, if it is an MBR, system migration software will transfer system partition (C: drive) and system reserved partition. If it is a GPT disk, besides system partition, EFI system partition and MSR partition will also be transferred to the new disk.

Honestly, this operation gives your computer a new life, which is also a brand-new experience for you, faster boot time, browse multiple webs smoothly, play games without stucking, etc. Have you not had this experience for a long time? To make it, you could try system migration with a professional system migration software.

Simple yet professional system migration software - AOMEI Backupper Professional

To migrate system and data on it, you need a professional system migration software which can take care of everything leaving you a few clicks to confirm the process. Here I strongly recommend you AOMEI Backupper Professional, which can help you easily and quickly migrate OS to larger HDD or smaller SSD per your needs. What’s really amazing about it is its ability to migrate system between MBR and GPT disks without converting partition style, and vice versa.

By default, this software only clone the used sectors on the system partition, which is usually used to migrate OS to smaller SSD. But you still can choose to clone all the sectors of system partition with its "Sector by sector clone" feature as long as the target disk has enough space to hold everything on the old system. Also, you are allowed to use its "SSD Alignment" to accelerate the reading & writting speed of an SSD disk.

Well then, what are the steps for system migration? Please keep reading below to get them.

Step by Step guide: perform system migration in Windows 10/8/7

Before you start to migrate system, you need to make some preparations:

  • Prepare a target disk, either HDD or SSD. If it's not initialized, please initialize the disk in the disk management.

  • Check both disk capacity and be sure the target disk is larger than or equal to the source. If not, the cloning process may fail.

• If you want to migrate system without loading Windows, you can create a bootable USB or DVD disk with this software and then boot from it.
• If you want to perform data migration purely, you could use "Disk Clone" to migrate data on the entire disk, or use "Partition Clone" to move data on specific partitions. No matter what you choose, it's all your decision.
• This version only supports Windows 10/8.1/8/7/XP/Vista. If you are currently using server computer, such as, server 2003/2008(R2)/2012(R2)/2016(R2)/2019, you could consider using AOMEI Backupper Server.
