Upgrade NVMe to larger NVMe SSD

NVMe, the abbreviation for non-volatile memory express, is an open logical device interface specification, developed for SSDs. Compared with SSD with ACHI, SSD with NVMe support enjoys better performance, lower latency, and higher input/output operations per second.

Due to its great property, it is a wise choice to turn to NVMe SSD. As time goes by, there are more and more data and applications being installed onto the NVMe SSD, the capacity of NVMe SSD can run out of space, and be unable to satisfy the demand anymore. Thus you might want to upgrade the current NVMe SSD with a larger one. For example, replace 128GB NVMe SSD with 1TB NVMe SSD. To stay out of trouble of Windows operating system and all other applications reinstallation, you can clone NVMe to NVMe SSD.

Get a powerful cloning software for NVMe SSD

It is extremely important to find out a proper hard drive cloning tool to complete NVMe to NMVE SSD copy with secure boot. Here AOMEI Partition Assistant Professional, a piece of great NVMe cloning software, designed for Windows operating system (all editions of Windows 10/8/7 and Windows XP/Vista), will be my first choice.

✔ It is capable of cloning NVMe SSD to NVMe SSD of different sizes and supports different brands of SSDs, such as Samsung NVMe SSD, Intel NVMe SSD, and WD NVMe SSD, etc.
✔ Apart from cloning an entire NVMe SSD, the cloning software can copy only OS-related partitions to another NVMe drive via "Migrate OS to SSD" function.
✔ What's more, it is with a sleek graphic interface and rather easy to handle for either computer experts or newbies.

Detailed steps to clone NVMe to NVMe SSD in Windows 7, 8 or 10

Now, install AOMEI Partition Assistant Professional on your computer; install the larger target NVMe SSD to your Windows computer (If there is only one NVMe M.2 slot, you can use an adapter from M.2 to PCIe for the second drive) and make sure it can be detected; initialize the new NVMe SSD as GPT; then check out the steps listed below to learn how to perform NVMe SSD to NVMe SSD copy.

PS.: It is available to download the demo version of AOMEI Partition Assistant to have a try at first.

Step 1. Run the software and go to All Tools > Disk Clone Wizard. In the pop-up window, you can choose a way to clone NVMe SSD to another NVMe based on your specific situation.


  • Clone Disk Quickly – clones only used space on the source disk and requires that the capacity of the target disk over the used space on the source disk. If you need to clone larger drive to smaller one, this way is suitable.

  • Sector-by-Sector Clone – copies every sector, unused sectors included, and demands that the capacity of source disk beyond the size of the target disk. To clone a hard drive with bad sector, you can choose this one.

Step 2. Choose the boot NVMe SSD you want to upgrade as the source disk.

Step 3. Select the new larger disk as destination disk and check Optimize the performance of SSD (If the target disk is HDD, uncheck the option).

Target One

Step 4. On this screen, it is available to adjust partitions on the target disk or leave it alone.


Step 5. You’ll go to the main console automatically. Click Apply and Proceed to execute SSD cloning operation.


Note: To clone NVMe to NVMe SSD in Windows Server 2019, 2016, 2012, 2008, you can use AOMEI Partition Assistant Server.

How to: boot from the new NVMe SSD after cloning

After complete NMVe to NVMe copy, you can remove the old NVME SSD drive, install the new one, and boot from it.

If your PC can keep two NVMe SSD drives simultaneously, you need to enter BIOS to set the new drive as the prior boot device to boot. Here are the detailed steps:

1. Reboot your PC and tap a functional key constantly to enter BIOS and choose "Enter setup".

2. Select "Change boot order" and set the new NVMe SSD as the first boot device.

3. Press "Enter" to boot from the new SSD drive.
