How to clone an SSD to a larger SSD by using EaseUS Disk Copy

Step 1: To start cloning your old SSD to another one, choose this old disk as the source disk in Disk Mode and click Next.
For your case, it’s the disk showing less capacity size


Step 2: After you insert the SSD into your computer via SATA-to-USB cable or hard drive enclosure,
it will be displayed as the picture shows. Choose it as your destination disk and remember to back it up if it has data.



Step 3: When you use EaseUS Disk Copy to clone your SSD, you can check the disk layout of the two SSDs.
“Autofit the disk” will make some changes by default on the target disk layout to make it work at its best status.
“Copy as the source” doesn’t change anything on the target disk, and the disk layout is the same as the source disk.
“Edit disk layout” will let you manually resize/move the partition layout on the destination disk.



Note: A message will appear warning you that data on your target SSD will be lost. Confirm this message by clicking Continue.



Step 4: After you edit your disk layout, you can click Proceed to start the cloning process.
