How do I transfer all data from old SSD to new SSD?

I currently have a Western Digital SSD drive where the Windows 10 is installed on. And I was planning to get a new SSD and wanted to migrate all data including the OS and installed games from the old SSD to the new one. So how can I transfer SSD to new SSD?

Apply a proper SSD cloning tool

To migrate a small amount of data from one SSD to another SSD drive, you can copy and then paste them into the new drive. But to move a large amount of data, that method will cost much time. Also, if you transfer applications through copy and paste, some can be unusable. Furthermore, if the SSD is a bootable drive and holds the boot files, directly copying and pasting them between two SSD drives will make the boot files useless. As a result, you cannot boot it successfully.

In those situations, it would be better to employ a piece of SSD cloning software called AOMEI Partition Assistant Professional. It provides "Disk Copy" function, which allows you to transfer SSD's files and applications to new SSD via cloning the entire Solid State Drive to another one. This method also works for cloning USB flash drive, SD card and other hard drives in Windows 10/8/7/XP/Vista.

Moreover, it also offers “Partition Copy” feature, enabling you to clone a specific partition to another drive, and its "Migrate OS to SSD Wizard" makes it convenient to migrate only OS partition to SSD or HDD.

Transfer all data from SSD to new SSD step by step

After getting a basic understanding of this SSD cloning software, you might want to know how to transfer data from old SSD to new SSD via its "Disk Clone" function. So, next we will show you how to perform it step by step.

Step 1. Install and run AOMEI Partition Assistant Professional on Windows PC. Right click the SSD you want to clone and select "Clone Disk".

Step 2. Choose a disk copying method based on your situation and click "Next".

Copy Disk Quickly


►"Clone Disk Quickly" will only copy the used space of the disk to another disk. So the destination disk must have to be larger than the used space of the source disk. This method can clone large SSD to smaller SSD.

►"Sector-by-Sector Clone" will copy every sectors of the disk to another one no matter it is used or not. So the target disk must be larger than the source disk. This method can help you clone BitLocker disk.

Step 3. Now select the target SSD to hold all content on the old SSD and tick "Optimize the performance of SSD". Then click "Next".

Select Destination Disk

Step 4. A warning about the data loss on the target disk will appear. If you have backed up vital files, click “Yes” to continue.

Step 5. Here, you can change the partition size on the new SSD drive. Click "Next" to proceed.

Step 6. Then, you will receive a note on how to boot OS successfully from the destination disk afterward. Read it carefully and click "Finish".


Step 7. Click "Apply" and "Proceed" to start the SSD cloning process.


Note: This guide is based on transferring/cloning the MBR SSD with OS installation to another GPT SSD drive. If you are about to do that, please ensure your motherboard supports the UEFI boot mode since you need to change into UEFI from BIOS, then you can boot your OS from the new SSD successfully. The vice versa is also true.

After it is done, all data on the old SSD have been copied to the new SSD drive.


So, with AOMEI Partition Assistant Professional, you can effectively transfer SSD data to new SSD. Furthermore, it is not only an SSD cloning utility to transfer data between two SSD drives, but also an SSD repair tool to help fix damaged or corrupted SSD. If you want to clone SSD to SSD in Windows Server, you can try AOMEI Partition Assistant Server.
